The objective of this study is to develop a simulation model of water utilization such as reservoir regulation, water intake and irrigation. This model is based on a distributed hydrological model developed by the authors. In this model, the entire river basin is divided into many grid blocks, the type of water utilization of all grid blocks can be defined. In this study, these data are stored in a database in which all grid blocks are arranged in the order same with the optimal routing order. In the simulation, the runoff generation is computed by using XinAnJiang model. The sum of runoff from a grid block and upstream river channels subjects to the water use, and then be routed to adjacent downstream grid block by using the kinematic wave method. In this study, this simulation model is applied to the Brantas River basin in Indonesia. The result shows the applicability of this simulation model.
