Abstract: A major hydroelectric project of Hydro-Quebec (Rupert River Diversion) required geophysical investigations at the location of future sites where weirs and cofferdams will be constructed. The engineers required accurate information of the rock profile and the bathymetry for adequate designs. These data were not accessible from conventional geotechnical and geophysical investigations methods in dangerous river rapids. An innovative bathymetric method, using the georadar technology was then set up and successfully used by Geophysics GPR Internatio...
