A generalized model employing a network flow algorithm and a heuristic database is being tested on the Qu'Appelle River basin in Canada. The heuristic database consisting of knowledge-based information relating to the various identified water resource needs in a basin is refined through runs of the model on supercomputer facilities for extensive historical periods of record. The basis of the model's solution is the simultaneous consideration of the hydrological events, hydraulic characteristics, and the heuristic data for a specified time horizon. The time horizon being defined as being the entire period for which a simultaneous solution is generated, can be divided into a variable number of equal unit-time periods (presently limited to 10). The selected unit-time period can vary from one day to one month. Real-time applications using either short- or long-term time horizons can be run with hydrological forecasts and climatological data.
