An Interactive Simulation Model for the Cedar/Tolt Water Supply System

摘要

In operating a water supply system, the ability to forecast inflows, and to take timely action to control demand is crucial to avoid unplanned supply shortfalls under critical streamflow conditions. Interactive simulation represents a useful tool to effect drought management strategies. An interactive simulation model of the Seattle water supply system was developed, that allows user interaction on a weekly time step in response to projected deficits from streamflow forecasts of length one, four, twelve, and sixteen weeks. Upper and lower forecasts are also predicted to occur under the lower forecast during the succeeding twelve weeks, user interaction is allowed to reduce demand and/or to adjust instream flow requirements.
