ABSTRACT: The paper models Kouilou-Niari River hydrodynamics at Sounda to estimate hydropower potential using long-term (1952-2013) flow data and energy-balance relationships. It quantifies seasonal discharge contrasts and propagates these into power and annual energy estimates for candidate turbine configurations. The main result is that a 4-Francis configuration at a net head near 68.5 m yields the best reported compromise, with high installed capacity and capacity factor relative to the other variants.
