Abstract

Planning, design and management of water resources systems nowadays unavoidably include impact predictions. Impact prediction demands modelling. In the present study the hydrological model WEAP21 was calibrated and then validated on Zarrineh Rud and Simineh Rud Basins. Zarrineh Rud and Simineh Rud rivers with a discharge potential of 3 billion m3 per year contribute a 50% portion to the Urmia Lake Basin. In the present study Soil moisture method was employed for the hydrological Simulation of model WEAP21. An 11-year statistical period (from 1994-95 to 2004-05) was planned for calibrating the model. The analysis of results of the model Simulation using the statistical indices showed that the coefficient of determination, Nash-Sutcliffe coefficient and index of agreement for different stations were respectively as follows: Inflow to Boukan dam hydrometry station: 0. 9, 0. 83, and 0. 95; Nezam Abad hydrometry station: 0. 75, 0. 74, and 0. 92; Dashband hydrometry station: 0. 82, 0. 81, and 0. 95 and Miyandoab bridge hydrometry station: 0. 75, 0. 75, and 0. 92. A nine-year time period (from 2005-06 to 2013-14) was planned for validating the model. The analysis of results showed that coefficient of determination, Nash-Sutcliffe coefficient and index of agreement for different stations were respectively as follows: Inflow to Boukan dam hydrometry station: 0. 88, 0. 85, and 0. 96; Nezam Abad hydrometry station: 0. 72, 0. 7, and 0. 91; Dashband hydrometry station: 0. 86, 0. 85, and 0. 96; Miyandoab Bridge hydrometry station: 0. 8, 0. 78, and 0. 93. In total, the results of Simulation revealed that the model presented an appropriate performance.
