Development of a Complex System Dynamic Eutrophication Model: Application to Karkheh Reservoir

Abstract The ever-increasing pollutant loads have significantly degraded the quality of receiving water bodies. High–resolution, spatially distributed water quality simulation models can be unsuitable at the planning/reconnaissance level of water resources decision making or for the rapid interactive analysis to support a participatory decision environment. This study presents a complex system dynamic (SD) eutrophication model in an object-oriented template to facilitate reservoir nutrient simulation process and assessment of alternative management strategies. The proposed model considers feedback and interactive loops between phytoplanktons, herbivorous zooplanktons, carnivorous zooplanktons, particulate organic matter, dissolved organic matter, ammonium, nitrate, phosphorus, total suspended solids, and dissolved oxygen in the simulation process. The reservoir SD eutrophication model is structured and expressed as a series of 30 differential equations for 10 state variables and three segmented layers. Th...
