Abstract: The present study focuses on the combination of a hydrologic simulation model and a climate reanalysis system for the estimation of a watershed's hydrologic characteristics, mainly stream flow, which will help in small hydropower plant's placement decision making. The SWAT semi distributed hydrologic model in the form of ArcSWAT extension for ArcMap, was used for running a series of hydraulic simulations of Ekaterini's stream watershed for extracting average monthly and annual streamflow data in each one delineated sub-watershed outlets by SWAT. Because of the lack of a weather station close to the study area with the adequate climatic data, weather parameter's time series generated by the global climate model Climate Forecast System Reanalysis (CFSR) were used as inputs for the SWAT model. The results of the simulation show a realistic prediction regarding the produced streamflow data in many predefined selection points within the whole watershed.
Keywords: GIS SWAT; climate forecast system reanalysis; CFSR; hydropower plant; watersheds.
