If your project provides a critical service, consider implementing basic measures to ensure the project can continue to function in the event of a flood such as having procedures in places to move vital equipment to safe areas. Ground Rupture (Active Fault) Ground Shaking. The Flood Impact Maps by DOST-ASTI were identified via Artificial Intelligence from a composite of three (3) Sentinel-1 SAR images. The agricultural damage is defined as function of flood depth, flood duration and growth stage of the. Listed also are the contact information of elected . use in any materials or services for sale or for which fees or charges are paid or received (e.g. If you require official hazards assessment reports for submission to banks or other government agencies, you may file your request at has.phivolcs.dost.gov.ph.Please provide us with proper vicinity maps and a copy of the TCT or Tax Declaration of the property. Kindly indicate your name, company name, if any, contact number and purpose of request. GeoRisk Philippines is a multi-agency initiative led by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), funded by the Department of Science and Technology (DOST) and monitored by the Philippine Council for Industry, Energy, and Emerging Technology Research and Development (PCIEERD) from 2018 to 2020. Early Warning Systems (EWS) are a key tool that can be utilised to reduce the damage that results from a flood event. This program requires the county to adopt and enforce floodplain management ordinances and development regulations to reduce future flood damage. The map displays the number of event(s) recorded per Region, as derived from warning agencies and offices. Identify and repair loose or damaged building components such as sheathing, soffit and fascia, shingles and roofing, brickwork, and jutting building features such as chimneys as all of these become potential debris in flood (as well as projectiles in wind). Batangas, Philippines Flood Map can help to locate places at higher levels to escape from floods or in flood rescue/flood relief operation. The map displays the number of event(s) recorded per Region, as derived from warning agencies and offices. a division of a local government unit (city or municipality, provincial, national); v. a division/subdivision of an international agency based only in the Philippines. In the case of large developments, encompassing significant proportions of a river catchment, a number of flood management procedures will be available, including measures to reduce and store rainfall-runoff. Flood hazard map of the World - 100-year return period The map depicts flood prone areas at global scale for flood events with 100-year return period. Before relocation is considered, it is necessary to obtain a more detailed understanding of the flood risk present at the specific site location. Fire Inspection of the establishment. Instead the implementation of flood defences, aiming to protect the structure or development from a floodplain, or the development of flood resilient structures, may represent the available options. If power were lost for 1 day, 1 week, etc. Shut off electrical power at the main building disconnect before the flooding occurs. In such cases, consult with your local jurisdiction for structural and safety requirements around replacing the building structure to its original location. Move important records and documents to a secure and protected area. textbook supplemental materials, books, syllabi, course packs, etc. Click on any point of the map and a text box will appear with flood studies at or nearby that location. If the dependencies are high and the cost of mitigation and redundancy are over budget, consider an alternative site for the project. This shapefile, with a resolution of 10 meters, illustrates the inundation extents in the area if the actual amount of rain exceeds that of a 100 year-rain return period. However, the non-existence of an event in these archives should not be used to infer the non-existence of a hazard. and present them to your finance team to inform the best decision for long-term risk management. The Environment Agency identified flood risk areas in their preliminary flood risk assessment. When a building is flooded at ground level and the foundation is breached, damage is exacerbated. No failure, omission or delay of the Phil-LiDAR 1 Program and the Licensee in exercising any of its right, privileges and remedies hereunder shall operate as a waiver thereof. Do not dismiss small streams as these can swell rapidly and dramatically in flood conditions and cause serious local flooding. Project planning decisions, project design, and construction methods must take into account the level of coastal flood hazard. Where coastal flooding is a product of cyclone winds, the most common debris include damaged building components and building contents, sediments, green and bacterial waste, and personal property. Most projects (even unrelated to infrastructure) rely upon public services such as electricity, water, communications, etc. Interviewing local staff and residents having local experience with any aspect of risks to your project. City Of Batangas, Batangas 25 Year Flood Hazard Map Abstract This shapefile, with a resolution of 10 meters, illustrates the inundation extents in the area if the actual amount of rain exceeds that of a 25 year-rain return period. Batangas, Philippines Flood Map may be useful to some extent for flood risk assessment or in flood management, flood control etc. The Project NOAH web portal provides critical information for disaster prevention based on near real-time weather data, flood and landslide hazard maps, storm surge inundation maps, and the identification of local critical facilities. Flash-flooding is unlikely to be represented in this tool, be aware that any small streams may pose a risk that is unaccounted for. Experts can also review recent historical events that have affected your region and how nearby buildings have performed under damaging flood conditions. BY USING THE PRODUCT, YOU ACKNOWLEDGE THAT YOU HAVE READ THIS AGREEMENT AND AGREE TO BE BOUND BY ITS TERMS AND CONDITIONS. Capacity enhancement of rivers: bypass channels and channel deepening/widening are measures that can be used to increase the amount of water that can pass through a river channel. Train personnel on emergency response procedures. All developments should be considered in terms of their potentially negative impact on local ecosystems, either through the removal of natural floodplain areas, or through the amplification of flooding. Post the Product and Derivative Works on your website with the quality of image data as a color composite jpeg without associated geospatial information, and in a non-downloadable, non-distributable, non-interactive fashion with proper copyright that is conspicuously marked alongside the Product. Further detailed information should be obtained to account for the risk from other hazards related to cyclones and other weather events. Batangas, Philippines Flood Map can help to locate places at higher levels to escape from floods or in flood rescue/flood relief operation. Basemap; Legend/TOC; Identify; Search; Editor; Help; Please wait. The likelihood of flooding is alluded to by the hazard levels provided in this tool. In case of non-agreement with the terms, the end-user is asked to return the Product delivered in its original form without copying or downloading. FRAs can be expensive, and should be undertaken by consultants with expertise in site specific flood risk assessments. It is caused by strong winds and low atmospheric pressures produced by tropical cyclones. In particular, ensure that the policy can cover aggregate weather hazards including those related to flooding (such as wind and extreme rainfall). Externally provided services may be based in a different physical location and therefore be subject to a different level of flood hazard. Flood hazard maps produced over large scales may highlight where there is a predominant flood hazard and will indicate the need to do more localised flood modelling with better topography and river channel data in these areas for detailed planning and engineering design. Foundation design strongly influences a buildings resilience to coastal flooding. power supply, computer networking and communications) then the vulnerability of these external services to flood should also be considered. For example, replacing large permeable areas with impermeable surfaces or structures will increase rainfall-runoff. Check to see if other planned projects in your area or upstream may affect your project, for example by moving water downstream to your site more quickly thereby increasing your sites flood hazard. 4. Flood hazard mapping is an exercise to define those coastal areas which are at risk of flooding under extreme conditions. The most important construction measures to minimize flood damage surround the foundation and its reinforcement as well as connections to the main building structure and the planned use of basement and lower stories. Our payment provider needs your Billing Address to retry your Card Payment. Batangas (13.71N, 120.57E - 015 km S 28 W), with the depth of . This analysis aims to identify whether relocating the asset, or making the asset resilient to flood is the most cost effective measure. Identify whether there are any additional sources of flood hazard present, that may not be captured in the Think Hazard! Context Water compatible* - infrastructure that does not result in damages, during a flood. If they do, it would then be necessary to identify whether the location of interest is situated in an area that may become flooded, usually by identifying whether the area is located within a natural floodplain (see Guidelines for Environment Risk Assessment and Management). Publication; FAQs and Trivias; Learning Tools; Research and Development; Information . water, electricity, transportation networks). Dependent assets may wish to consider implementing a backup service if deemed necessary. Consider implementing an Integrated Flood Management approach where possible (see APFM). A flood risk appraisal will highlight key areas where a more detailed study may be required. Please note that these have not been validated on the ground and the thematic accuracy might be lower in urban and forested areas due to inherent limitations of the SAR data and processing used. a. Is this river connected to your site via a floodplain? The identification of previous events occurring at a given location will clearly indicate the presence of a significant hazard. If the project involves construction, there may be relevant building standards that apply to the project regarding flood risk, e.g. Damage and disruption to the local transportation network may not disrupt the functioning of a facility, but it can prohibit personnel from reaching critical infrastructure or an emergency facility. Documentation of previous events, through local news reports, can also provide a useful insight into previous events, and help to define flood risk at a more local scale. Since flooding is a very local phenomenon, the hazard information provided by this tool should be considered the preliminary action in defining river flood hazard level. It is the region's center of tourism, education . Skip to Site Map The iGovPhil Project officially adopts the Web Content Accessibility Guidelines (WCAG 2.0) as the accessibility standard for all its related web development and services. For high vulnerability assets, consider commissioning a flood risk appraisal, with the aim being to provide a detailed understanding of local flood risk. Sufficient drainage systems will need to be in place to transport the excess water that previously would have been absorbed by the landscape, away from the site. Information about flood hazard can take multiple forms, this includes spatial maps of flood hazard, flood zoning information, reporting of previous events and local knowledge. Tsunami. These flood models themselves are subject to significant uncertainty and therefore their output should be used tentatively. In the area you have selected (Batangas) river flood hazard is classified as low based on modeled flood information currently available to this tool. It can also provide floodplain map and floodline map for streams and rivers. Your plans should include specific conditions that will activate the plan, a clear chain of command and orders of responsibility, a list of specific emergency functions and who will perform each of them, evacuation procedures, including evacuation routes and emergency exists, and procedures to account for personnel, customers, and visitors as appropriate. Storm surge becomes more dangerous when it arrives on top of a high tide. If theres time, duplicate records and move offsite. With this prior knowledge, your project managers can evaluate mitigation and risk transfer options well before construction begins and plan accordingly. Consider getting guidance on how to integrate your development into local flood management practices (see APFM). The consequence of flooding, that being the damage or loss of life that results from a flood, depends upon a number of factors including the vulnerability of the exposed asset. . Measures to reduce runoff: replacing impermeable surfaces with natural landscapes and afforestation are measures that will reduce the rate at which rainfall moves across the surface of a catchment and into a river. Legazpi is the regional center and largest city of the Bicol Region, in terms of population. Examples include flood defences, amenity open space, sports and recreational ground, docks and marinas. WCAG 2.0 is also an international standard, ISO 40500. The limitations of these data, particularly those produced over large scales, cannot be overstated. Batangas, Philippines Flood Map may help to provide flood alert/flood warning if flood water level at certain point is rising. Please contact for further information. For projects that relate directly to critical infrastructure (such as a hospital project, utility expansion, or communications facility), there is a greater need for the assets to function post-event either to maintain essential services or to provide emergency response and recovery efforts. rain-induced landslide hazard map . use in any books, news publication or journal without an educational purpose. The checklist can be customized to each stage of your project or draw attention to tasks more critical in a particular stage (e.g., construction sites will have more potential outdoor airborne debris). Buildings damaged by coastal flooding often suffer wind damage as well. Be wary of the location of emergency response equipment, in particular electrical generators. The frequency of flooding within the indicated flood prone zones . The voluntary commitment shall continue to be in force and effective even if any entity undergoes any changes in its organizational structures/officials or its functions assumed by another agency or office. Mitigation The implementation of flood defences will, by its nature, remove some amount of floodplain storage and exacerbate flood risk elsewhere. Your card will be charged after your 7 days trial ends. Climate change impact: According to the IPCC (2013), there is high confidence that extremes in sea level will increase with mean sea level rise yet there is low confidence in region-specific projections in storm surges. Even if the equipment is accessible, it may be damaged or completed inoperable at a time when it is most needed. Floods have destroyed people's lives as well as social and environmental assets. For low flood hazard areas, highly vulnerable assets should be considered for relocation. Are there insurance products that can protect the project from such an interruption (see insurance section)? Others. For small-scale developments, the implementation of upstream, flood alleviation measures may not be possible. As with wind, rapidly moving flood waters can carry large and heavy debris that upon impact can cause direct physical damage. Less vulnerable - assets that would not significantly exacerbate the impacts of a flood, but would result in damages. You can use tools such as published maps, Google Earth, or open source GIS software such as QGIS, to identify nearby waterways. In high-risk areas along the immediate coastline, carefully design around your BFE (Base Flood Elevation). These considerations also apply to flood defences and channel conveyance measures. assessment for related hazards in this region: cyclone wind, river flood, and landslide. Play out disaster scenarios (scenario planning) on your project to stress such conditions and to plan how to respond. When a warning is issued, be aware of the meaning of such a warning and be prepared to clearly communicate its implications to your personnel and visitors. Check whether there are any streams or rivers in your project area. This means that there is a chance of more than 20% that potentially damaging and life-threatening urban floods occur in the coming 10 years. Sell, license, rent, transfer, give away, disclose, copy or reproduce (even if merged with other materials) create derivative works other than the allowed permitted uses; c. Post the Product in internet websites in a non-secure format that will allow manipulation; d. Alter or remove any copyright notice contained in or on the Product; and. The project aims to enhance the disaster-forecasting capabilities of PAGASA by beginning to generate detailed maps of storm surge and inundation susceptibilities by using Japan Meteorological Agency storm surge model in simulating 721 tropical cyclones that entered the Philippine Area of Responsibility from 1951-2013. This can range from management of upstream catchment areas, through to the implementation of flood defences. If the service provided by your project is critical, the effect of flooding on your projects ability to provide the service should be assessed. Step 1: Click the icon for flood. These classifications provide a useful blueprint to determine the vulnerability of a given project or asset. A site specific FRA represents the most detailed appraisal of flood risk at a given location. groundshaking hazard map. It simply means that an event has not yet been recorded officially. Often the restoration of natural wetland areas will alleviate flood risk, whilst also providing additional benefits to local eco-systems. Examples include emergency response units, hospitals, power stations, installations of hazardous materials. c. remove/delete all copies of the Product or any portion thereof from all computer storage devices or places where the Product is stored. But this flood map should help in some extent in the following areas: The elevation layered on the map is in meters and is from sea level. Adopt your own emergency response procedure leveraging response plans already in place regionally. Organization type based on Phil-LiDAR1 Data Distribution Policy. In some areas, rivers may not run all year around; such 'ephemeral' rivers are still capable of causing significant flooding at certain times (this type of river is most common in arid and semi-arid regions). Be sure to review the ThinkHazard! Identify debris that may have been deposited during previous flooding. Examples include residential buildings, educational and landfill facilities. Do not dismiss small streams as these can swell rapidly and dramatically in flood conditions and cause serious local flooding. Climate change impacts: Medium confidence in more frequent and intense heavy precipitation days and an increase in the number of extreme rainfall events. News and Press Release in English on Philippines about Earthquake, Flood and more; published on 24 Jul 2021 by AHA Centre . The main purpose of geologic hazards maps is to identify where geologic hazards may be present and where additional evaluations are needed to assess hazards and recommend mitigation measures prior to development. Conduct cost/benefit analysis to determine if on-site backup power generation is an option within the budget. Shut off supply lines to flammable liquids, combustible liquids and gas at their source. If practical, move outdoor storage and unanchored property indoors. Negative elevation means depth below sea level. When practical, temporarily relocating a building provides the greatest mitigation against coastal flood risks. In case you, as a Licensee, do not agree to these terms and conditions, Phil-LiDAR 1 Program is not willing to license the Product. Batangas City, the capital of Batangas Province has a total land area of more or less 28,541.44 hectares. Cell values indicate water depth (in m). The present hazard level may increase in the future due to the effects of climate change. the fhm approach has three main components, namely: (a) advanced identification of flood-prone areas and locating of such areas in a flood hazard map; (b) advanced designation of evacuation sites in times of flooding; and (c) the dissemination of information to the people about the flood-prone areas and the evacuation sites, including its If the river system that poses a hazard is represented, then GLOFAS can be used to provide a provisional EWS. Note that flood risk may not always originate from the closest point on the river; you may also be at risk from flood waters that overflow from the channel upstream before flowing downhill over the floodplain. Global Flood Map uses NASA satellite data to show the areas of the world under water and at risk for flooding if ocean levels rise. Essential Infrastructure - all infrastructure that cannot be relocated, regardless of hazard level. In major coastal flooding events flood debris is inevitable, especially in built up areas, but often unplanned for. Site specific evaluation is needed for construction of major structures and lifelines. A flood risk appraisal differs from a site specific FRA, in that it provides a more localised view of flood risk (than provided by the Think Hazard tool), but still a broad view of flood risk. These procedures will have already taken into account the significant hazards inherent to your region, including coastal flood hazards and other related risks to your project. Flooding may inundate the lower levels and render generators and other critical assets inoperable. The relocation of more vulnerable assets is highly advised. c. Make limited copies of the Product for internal use of the organization. In the area you have selected (Batangas) coastal flood hazard is classified as high according to the information that is currently available. For further information the following resources could be consulted: If you have any, please provide feedback. Surface runoff, flow diversion, land type etc. A Highly Vulnerable asset, such as a hospital, will require a detailed understanding of flood risk. Consult local flood zoning information (if readily available). Mines and Geosciences Bureau. For lower vulnerability assets, consider seeking informal guidance from professionals with expertise working in the area. After construction is complete, experts can evaluate the scientific literature published since construction began to determine if the risk is even higher than previously suspected and also suggest additional steps to increase resilience. For high flood hazard areas, relocation to areas with a lower hazard level is recommended where possible. 2 Jan, 2018. Notes:Before using this Flood Map application, please note that for various technical or non technical reasons the application is not guaranteed free of bugs or inaccuracies. For example, a common structural mitigation for river floods is in the use of reinforced concrete footings and attached piers. Disaster Risk Reduction and Management Plan (LDRRMP) of the City of Naga, Cebu. No waiver or departure from the terms of this Agreement shall be valid unless made in writing and signed by both partys authorized representative. Thus, even when the project itself is not damaged by the impacts of coastal flooding, it may not remain functional due to disruptions in critical infrastructure. The pictures are originally from a PDF document that DILG makes available on its web site. But if you cancel the plan before your 7 days trial ends, your card will not be charged. Your Card payment failed due to Billing Address unavailability. Keep in mind certain finish materials (e.g., carpeting) tend to retain moisture and develop mold days or weeks after a flood event ends, posing a serious health hazard if the building is reoccupied prematurely. In some areas, rivers may not run all year around; such ephemeral rivers are still capable of causing significant flooding at certain times (this type of river is most common in arid and semi-arid regions). (OPV) of Batangas was held on November 03-04, 2022 via Zoom. If this more detailed information indicates the present site to be at risk, it may be possible to relocate your project to a different site within the same administrative area that is known to be less susceptible to flooding. Note: There is a 1/100 (1%) probability of a flood with 100 year return period occurring in a single year. As a part of a long-term maintenance strategy, identify and remove small trees and branches from larger ones that could detach during a flood event and pose debris risk to the building. It is about 108.00 kilometers away from Manila and has an average travel time of approximately one hour forty-five minutes through the Southern Tagalog Arterial Road (STAR) tollway and the South Luzon Expressway (SLEX). Production Areas Exposed to Hazard 25 Figure 9. FLOODING. This layer is not currently used in any maps. 1km). They will need to have appropriate skills in hydrology, hydraulics and computational river modelling. In receiving the Product and signing this Agreement, the Licensee acknowledges to be bounded by all terms and conditions stipulated herewith. Anyone The following users: The following groups: Batangas Province Flood and Landslide Susceptibility Maps. With its ten (10) barangays, its area comprises 4.7% or 5,993 hectares (has) of the provincial land area. Barangay Map. More vulnerable - assets that would result in significant damage should they become inundated.

Most Agusan del Sur parts are affected by floods whenever there's heavy rain, from Prosperidad, La Paz, Las Nieves, Bayugan City, Esperanza, Talacogon to Loreto, San Luis, San Francisco, Bunawan, and Patin-ay. September 21, 2020: 16:40: REGION 6: Progress Report for Flash Flood due to Continuous Rainfall in Palimbang, Sultan Kuldarat (REGION XII) . They may have an intricate knowledge of flood hazard, as well as being able to identify key datasets in the region. The presence of large objects, such as boulders, in the vicinity of even seemingly small waterways may indicate the presence of powerful flood waves. However, owing to their coarse resolution, national or regional food hazard maps should not be used to provide information at local (building) scales and certainly not to inform engineering design. However, such approaches will likely require a framework for collaboration across many different sectors and organisations. Submit it to the DOLE Office having jurisdiction over your company- have a receiving copy for filing. Experts can provide significant value to your project since the risk is significant. Monitoring of flood events is becoming more routine, with a number of centres building archives of previous events (see Dartmouth Flood Observatory[http://floodobservatory.colorado.edu/], Disaster Charter [https://www.disasterscharter.org/web/guest/home], and Copernicus [http://www.copernicus.eu/]).
