Examples include flood defenses, amenity open space, sports and recreational ground, docks and marinas. If sufficient warning can be given, then mitigation procedures can be implemented; these may include evacuation, movement of vulnerable assets/material or the implementation of temporary/moveable flood defences.

Below is the complete Batangas Tsunami Hazard Map from Phivolcs. Please note that these recommendations are generic and not project-specific. flood hazard map of batangas.
These considerations also apply to flood defences and channel conveyance measures.
o For large developments, consider implementing flood management procedures, such as the provision of storage areas for excess river flow, or the implementation of measures to reduce rainfall run-off.
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. But if you cancel the plan before your 7 days trial ends, your card will not be charged.
Flood hazard maps may be available from government agencies or through local consultants, and may be available at a variety of scales. Flooding is most likely to occur in relatively flat areas beside rivers (floodplains), in local low-points in the land surface (depressions), or along valley bottoms. 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.
Where possible, this integrated approach to flood management represents the ideal approach to alleviate flood risk. o Consult local open access flood hazard maps (if readily available). WebA flood hazard map developed using LiDAR DEM was utilized for the Boac and Mogpog rivers for an accurate representation of flooding events.
Aside from direct human impacts, the impacts of a development on local flood behaviour should also be considered from an environmental viewpoint.
If excess rainfall cannot infiltrate the land surface it will flow over it, generating flood hazard.
Where possible, this integrated approach to flood management represents the most ideal approach to alleviate flood risk.
Buildings and developments also have the potential to exacerbate downstream flood risk by reducing floodplain storage capacity.
Further clarification of the local river flood hazard will be required. o Ascertain the feasibility of a real-time connection to the EWS. 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.
The Phivolcs Tsunami Hazard Map shows the WebDiningHours. 3 shows the surrounding fault lines in the province of Batangas.
Floodplains are valuable ecological resources that will provide a habitat for a wide variety of plants and animals. o Consult local flood zoning information (if readily available). 2.
Therefore, for all hazard intensities greater than Very Low, a site specific FRA would be highly recommended. WebBATANGAS CITY is classified as a Regional Growth Center in the CALABARZON region. Show abstract. It may help flood risk assessment or flood management. Understanding vulnerability, along with hazard level, is a crucial component when determining whether a location is suitable for development.
Identify whether there are any additional sources of flood hazard present, that may not be captured in the Think Hazard!
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. After clicking the link for map download, click the region where your area or property is located.
o Only water compatible, essential infrastructure and less vulnerable assets should be considered in areas with medium flood hazard. Attempt to identify the origin of the hazard identified by the tool.
Flood hazard maps provide an estimate of the likelihood of flooding at a given location. Regardless of the measures implemented, it is important when implementing flood management measures that they are not treated in isolation; their impact on other areas may be significant.

These studies are typically desk studies that will attempt to provide a generic assessment of flood risk by pooling together available information, and perhaps undertaking some coarse scale modelling. If a development removes space that previously stored excess water, the scale and/or speed of run-off will increase. o Consider getting guidance on how to integrate your development into local flood management practices (see the Associated Programme on Flood Management).
If your project will contribute to urbanization of low-density developed areas, its effect on flood hazard may be more significant.
Acquisition of available flood hazard data should be undertaken for all sites and all hazard levels. However, the non-existence of an event in these archives should not be used to infer the non-existence of a hazard. Otherwise your payment will fail and you will not be able to access FloodMap Pro after your trial ends. rural areas or the outskirts of towns and cities), as flood management in more built-up urban areas is often under the control of local and national authorities.
Early Warning Systems (EWS) are a key tool that can reduce flood impacts.
Is this river connected to your site via a floodplain? WebAccording to the 2011 Philippine Disaster Report of the Citizens Disaster Response Center (CDRC), flood topped the list of the five (5) disasters in 2011 with 121 reported incidents or 28% of the total number of disaster events monitored in the same year. For further information the following resources could be consulted: If you have any, please provide feedback. The limitations of these data, particularly those produced over large scales, cannot be overstated. A more detailed understanding of flood risk can be obtained via a flood risk appraisal.

Identify whether this hazard poses a risk to your asset. Highly vulnerable - assets that would acutely exacerbate the impacts of a flood, should they become inundated. The City of Batangas is a coastal city lying in a cove like shape at the southeastern portion of Batangas Province and geographically situated at coordinates 13 degrees, 45 minutes and 25.96 seconds north latitude and 121 degrees, 3 minutes and 29.2 seconds east Examples include shops, cafes, non-residential establishments, waste treatment (non-hazardous), agricultural buildings and land. Floods dont follow city limits or property lines. Using a flood map, you can see the relationship between your property and the areas with the highest risk of flooding. There is no such thing as a no-risk zone, but some areas have a lower or moderate risk. Always ask for detailed examples of relevant experience from any consultant you wish to hire for these purposes. The level of professional guidance will depend largely on the vulnerability of the project or development and the identified hazard level.
Flood hazard maps may be available from government agencies or through local consultants, and may be available at a variety of scales.

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.
3 levels of hazard:Low Observations of previous flood events can also be used to define flood hazard. In particular, flash-flooding and flooding from small waterways is unlikely to be represented in tool. Only water compatible projects, and essential infrastructure that cannot be relocated, should be permitted in these areas. Note: There is a 1/25 (4%) probability of a flood with 25 year return period occurring in a single year.
Consider getting guidance on how to integrate your development into local flood management practices (see APFM).
Large scale EWS also exist; GLOFAS is a global EWS for large scale flood events. 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.
For large developments, consider implementing flood management procedures, such as the provision of storage areas for excess river flow, or the implementation of measures to reduce rainfall run-off.
