This paper presents ongoing research into the automation of control curve generation and the development of an expert system for reservoir management for North West Water of Warrington, England. The paper begins with a brief introduction to the NWW and their use of control curve analysis for planning and operation. Next, a procedural computer program entitled SCREEN (Simulation Model for Control Curve Generation and Evaluation) is described that automates all phases of control curve analysis to increase the speed and ease with which control curves can be developed and evaluated. The paper then describes an expert system, ESCORT (Expert System Control Curve Analysis and Reservoir Tracking) that guides water managers through the development of operational strategies during droughts. A discussion of the knowledge acquisition process used to develop the expert system is also presented. The remainder of the paper addresses the incorporation of operational rules into the expert system and experience to date.
