Short summary
Creation of surface storage often endanger the functions of natural ecosystems and ecosystem services. The issues of optimal size, placement and the number of reservoirs in a river basin, which maximizes sustainable benefits, while minimizing negative impacts on ecosystems remain subjects for debate. This study examines the above issues through the analysis of a range of reservoir configurations and environmental flow release scenarios in the Malwatu Oya river basin in Sri Lanka.
