Coğrafi bilgi sistemleri tabanli çok ölçütlü hidroelektrik potansiyeli seçimi

This study carries out a feasibility analysis of hydropower potential for a river basin in North Iraq based on geographical information system (GIS). By using ArcGIS tools, the topographical features of the site were analyzed and the boundary of Sidakan basin and its sub-catchments were derived. Four different hydroelectric power plant alternatives were analyzed, consist either a set of sequential dams or a single dam with a relatively large reservoir. Hydrological analysis of available rainfall and discharge data revealed the storage capacity of each dam alternative, the peak discharge and flow duration curve (FDL) of the available river flow. The firm capacity and design flow for each alternative were computed, as well as geometrical designs of other components of each dam. The benefit/cost ratio (B/C) for each alternative was computed based on 50-year return period.
