Abstract: The primary aim of this research was to investigate and to substantiate available methodologies based on key hydrologic, hydraulic and geometric parameters of a river to derive the theoretical hydrokinetic (HK) power. To realize this aim, hydrological and hydraulic methods were applied for the second largest river in the country. For the hydrological evaluation of the hydrokinetic resource historic, standard, stream gauging stations records (river stage, flow and velocity–area) analyzed. The one-dimensional hydraulic model HEC-RAS 4.1 was used with the GIS extension GeoRAS to perform river hydraulic calculations. A high-resolution digital elevation model of the streambed was employed. The model calibration to adjust Manning׳s coefficient was performed after the stream surface slope and discharge were measured.
