Abstract
Nowadays, we see the growth and development of several models for the design of water supply systems, flood estimation, allocation and use of water resources, runoff and wastewater management in urban areas and management of aquatic ecosystems. Understanding the water yield and water demand is one of the main components of decision making for the management of resources, watersheds and phenomena such as drought. The lack of a system that supports correct decision making and timely decisions is entirely evident for management of surface waters and drought risk in the country. For creating of fetus system, it is necessary reviewing and assessing the water yield in the country. In this study, the 7th order basin in the Markazi province, that is located in the semi-arid climate, are simulated and analyzed with using rainfall, evaporation and discharge data by using of AWBM and SFB models. The main objectives of this research are included of extracting physical parameters of the model, conversion of rainfall point data into regional data using different methods and routine, analysis of calculated evaporation and evapotranspiration and aggregated of data for simulating the 7th order basin and estimation of potential surface water yield Markazi province.
