Abstract

Dynamic stream flow (River Ecosystem) becomes static mound (Lake Ecosystem) after constructing dam on the river. The most important difference between them is of retention time and stratification which induce different qualification to water river prior to reservoir and afterwards. In this study, heat distribution within15- Khordad Reservoir was simulated using 2-D laterally averaged CE-QUAL-W2 model during the year 1997.Then, results which obtained through this model were made comparison by those of 1-D DYRESM model and field data as well. Results showed that both of models are succeeded in simulation of the reservoir temperature profiles in turn over period, hypolimnion and metalimnion forecasting. But DYRESM model was weak in simulation of epilimnion temperature forecasting in stratification period. In the following, two models were used to calculate the heat flux relationships that are aimed at achieving these differences. Since 15Khordad dam is located in an area which evaporation is an important factor, two different equations to calculate the heat flux model is used to evaporate, lead to underestimation of the actual amount of evaporation in the DYRESM model and the difference in temperature epilimnion simulations compared with measured values.
