The following are programs designed to simulate water development and management policies in river basins. They are generic in that they are designed to be applicable to a wide variety of specific river basin water resource system configurations, institutional conditions, and management issues. Each of these example programs is based on a nodelink network representation of the water resource system being simulated. Some include optimization that replaces a more detailed representation of operating policies. All contain menudriven graphics based interfaces that facilitate user interaction. These programs are appropriate for use in shared vision exercises involving stakeholder involvement in model building and simulations. The brief descriptions below have been taken from the model web pages.
