An ecohydraulic-based expert system for optimal management of environmental flow at the downstream of reservoirs

Linking ecohydraulic modeling and reservoir operation optimization is a requirement for robust management of the environmental degradations at the downstream of the reservoirs. The present study proposes and evaluates an ecohydraulic-based expert system to optimize environmental flow at the downstre...
