The Flood Forecasting and Warning system for Dam Operation (FFWSDO) aims at the establishment of telemetered flood forecasting warning system that will provide the necessary information for the safe and cost effective operation of the existing five major dams in Luzon and to forewarn the people in the flood plains downstream of these damsites of the impending release of impounded water through spillways during typhoons. Phase I, involves the establishment of a FFWS covering Angat and Pantabangan watershed areas, while Phase II, involves the establishment of a FFWS covering Magat and Binga/Ambuklao watershed areas.
The Agencies directly involved in the implementation of the project such as NPC and NIA are dam authorities who operate and manage the Angat and Binga/Ambuklao Dams and Pantabangan and Magat Dams respectively amd the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) through its Flood Forecasting Branch which operates the flood forecasting warning systems. Monitoring agencies are the Department of Public Works and Highways (DPWH), Office of Civil Defense (OCD) and the National Water Resource Board (NWRB).
The complete FFWSDO has the following basic system and components:
- Real-time telemetering system consisting of the optimum number of rainfall and water level gauging stations
- Real-time processing computer system to forecast flood water inflow to the reservoir based on the telemetered rainfall data;
- Flood warning system with warning disseminationfacilities and supervisory control stations in dam offices;
- Overall supervisory system for the operation of the above system in the respective Central Offices of NPC, NIA, and PAGASA;
- Monitoring system which will allow exchange of necessary information among the participating agencies in flood control and other related activities; and
- Telecommunication system which provide the means for continuous information flow for the operation of the above system.
The project will result in the effective use of the hydrological data and information for the efficient operations and management of reservoirs and ensure the optimum use of the impounded water for power generation, irrigation, flood control and domestic water supply, the mitigation of flood damages, particularly loss of human lives, by timely and adequate warnings of impending release of impounded water through the spillways.
