This study is an application of the simulation-dynamic programming approach for the evolution of a water regulation policy for the Pantabangan reservoir of the Upper Pampanga River Project, in conjunction with two tributary reservoir systems: the Aurora Transbasin Diversion Project and the proposed Casecnan River Project. The study may be decomposed into three sequential phases: 1) a reservoir operations simulation study of the existing two-reservoir system and the three-reservoir configurations for three alternative Casecnan dam locations. The operations simulation was centered at the Pantabangan reservoir and was performed under parametric conditions of invariant service area cropping pattern, power generation, flood control release schedules, and average system microclimate. The principal variables were the reservoir system and service area runoffs which were inputted as synthetic streamflow traces. The results of the simulation study, in the form of Pantabangan irrigation and power releases, were inputted for optimization in 2) a dynamic programming model which is of the explicit stochastic type. The probabilistic property of the model is ascribed to the use of lag-one monthly transition probability matrices and relative frequency matrices to respectively characterize the behavior of the unregulated Pantabangan reservoir inflows and the transbasin diversions. Due to the rough discretization procedure conducted on the optimization variables, the determined operations policy was tested in 3) a feasibility simulation model which features essentially the same parameters and variables of the operations model. Two sets of policies were tested under the two- and three-reservoir arrangements. The first is a constrained policy based on a minimum Pantabangan reservoir storage greater than the physical minimum. The unconstrained policy was based on dead storage as the minimum.
