Water supply headworks simulation using network linear programming

Abstract A water supply headworks simulation software package called WATHNET is described. It uses a simulation model based on a network linear programming formulation which makes the model independent of system configuration, avoids the need to define detailed operating rules, and allows simulation of systems changing over time. Particular emphasis is given to describing the user environment which consists of a portable, mouse-based graphics interface and the tools to which it provides access. This environment helps realize the potential of the model, providing tools which streamline the complex task of system definition and data preparation, and which present results in a readily comprehended form. A case study is used to illustrate significant features.
