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 reservoir ecosystem have been modelled, by assuming stratified layered and parcels structure, to predict the water quality and algal species composition in the reservoir. The state variables, temperature, four types of phytoplankton as chlorophyll-a, soluble phosphorus, nitrate, ammonium, dissolved oxygen, biochemical oxygen demand, internal nitrogen, internal phosphorus, and when diatoms are modelled explicitly silica, are considered in the model.
