Abstract. In the Volta Basin, infrastructure watershed development with respect to impact of climate conditions is hotly debated due lack adequate tools model consequences such development. There an ongoing debate on further small and medium scale reservoirs water level Lake Volta, which essential for hydropower generation at Akosombo power plant. The GLOWA Project (GVP) has developed a Basin Water Allocation System (VB-WAS), decision support tool that allows assessing in basin availability current future resources, given or conditions. simulated historic discharge time series joint climate-hydrological modeling approach (MM5/WaSiM-ETH) serve as input data river management (MIKE BASIN). MIKE BASIN uses network approach, fast simulations allocation different scenarios available resources. expansion stored volume been quantified assessed comparison variability resources basin.
