Application of a Two Dimensional Model to Predict the Effects of the Curtain Method on Algal Blooming in Reservoirs

Abstract

As one of the ways of reducing algal blooming in T-Dam reservoir, two vertical curtains, having depths to cover the epilimnion thickness, are installed across the reservoir in order to curtail the nutrient supply from nutrient-rich inflow to the downstream epilimnion of the reservoir. The physical and biological process in the reservoire cosystemh ave been modelled, b y assumings tratifiedl ayereda nd parcels structure, t o predictt he water qualitya nd algal speciesc ompositionin the reservoir. The state variables, temperature, four types of phytoplankton as chlorophyll-α, soluble phosphorus, nitrate, ammonium, dissolved oxygen, biochemical oxygen demand, internal nitrogen, internal phosphorus, and when diatoms are modelled explicitlys ilica, are consideredin the model.
