Determination of the Best Model for Flood Flows in the Western Basin of Lake Urmia

Today, the management of water resources has been taken into consideration based on sustainable development in the world. Natural events such as floods have been among human problems in the past and present and hydrologists have always given lot attentions to this issue. Determination of the amount of the flood in drainage basins depends on hydrologic and hydraulic parameters of the basin. The purpose of this study is to provide the best model of the flood flow of drainage basin of West Lake Urmia. For this reason, after preparing the required statistics during two statistic periods for the 34-year, several equations were developed for estimating flood flow that in these relationships, flood flow parameter has been estimated as the dependent variable by using independent variables such as rainfall, the annual average temperature and physical characteristics of the basin. Finally, 4 models out of 112 models were selected as the best models to predict the area flood and the respective relationships were presente
