Reservoir Planning and Operations Studies with Optimization-Simulation Models

Abstract

This chapter discusses the application of combined optimization-simulation models for reservoir planning and operations studies to assess the ability and reliability of three reservoir systems to deliver water for domestic and/or irrigation water supply, hydropower generation, and possible flood control function. The three reservoir systems presented here are as follows: (1) Angat Reservoir which has a multipurpose function for domestic water supply to Metro Manila, irrigation water supply to Angat-Maasim area, hydropower generation for the Luzon electric power grid, and flood control for its downstream communities; (2) Upper Agno River Basin reservoir for hydropower generation for the Luzon power electric grid, irrigation water supply to Agno River Integrated Irrigation Project, and with significant sediment trapping storage for water quality control; and (3) proposed Agos Reservoir system as future water supply reservoir for Metro Manila. In the Agos Reservoir system, the Kaliwa Low Dam in particular has recently been approved by the national government to be constructed.
