Abstract
A simulation/optimization {S/0) model is presented for optimizing pollutant loading to a stream while adequately protecting surface water quality. The S/0 model represents surface water quality response to point and non-point loadings via simplified constraint equations. These equations are developed before optimization via analysis of simulated system response to systematically imposed loading. Considered pollutants include BOD, ammonia, nitrate, total nitrogen, and total phosphorus (organic and dissolved). The S/0 model is applied to a hypothetical agricultural setting. Post-optimization testing of simulated system responses to optimal loadings show that the simplified constraint equations are satisfactorily accurate at predicting downstream concentrations.
