Abstract: During the drought of 1988, water users in the Kanawha River, West Virginia, became painfully aware of conflicting uses that have developed since the 1970s. A numerical modeling of the Kanawha River was conducted to evaluate the effects of different operation scenarios on river users - including water quality flows. The model was created with the object-oriented programming language, STELLA. The model includes user-developed Boolean statements to create an expert system. STELLA, using the expert system, was able to accurately reproduce the water management decisions and river flow for 1988 which included flood releases, minimum flows, lake storage balances, and downstream water quality targets.
