The Angat Reservoir is a multipurpose reservoir serving competing uses for Metro Manila’s domestic water supply and Bulacan’s Angat-Maasim River irrigation system with a privatized hydropower generation component. This study assesses the reliability of Angat Reservoir operations to deliver these demands with an increased domestic water supply requirement from 46 to 50 m3/sec and with future reservoir sedimentation in 2050. A reservoir optimization simulation model is employed to simulate daily reservoir operations with long-term generated inflows from a watershed model. Then, the resulting daily reservoir releases for each scenario are subjected to flow duration analysis in the context of reliability analysis to assess the competing water uses of Angat Reservoir.
