Characterization of the effects of manantali dam on the hydrological regime of the Senegal river by the IHA/RVA method

Abstract

Stream flow regimes are considered the main driving force of their ecosystem.1 The stability of river ecosystems is largely dependent on the natural dynamic change characteristics of river flow.2 The water resources management has led to a change in the natural flow of rivers around the world3 that affects water quality, energy sources, physical habitat, and biotic interactions.4 To conserve water, many dams have been built along waterways and regulate the flow of a river. This regulation by dams modifies the natural flow mode of the rivers. This characterization of natural regime can be done by a number of hydrological indices and methods taking into account not only hydrological parameters but also ecological parameters.
