Hydraulic studies on Son La hydropower project to selection river diversion scheme

Abstract

     The hydraulic tests were implemented on the spatial models with the scales of 1:80÷1:100 for the flood discharging during construction period. The phases of flood discharging through the riverbed which was narrowed by the cofferdam, the construction channel, and the diversion conduits were also considered. The flow conditions and the alluvial deposit deformation at downstream of the project were specified from the hydraulic tests for different phases of construction period. The dimensions of the discharging structures during construction period were also precisely specified.
