Overtopping of partially completed rockfill dams is being increasingly used as a means of reducing diversion costs during construction. Based on the results of laboratory tests, a method is described for determining head discharge relations and for approximating pressure and flow distributions within a homogeneous rockfill bank of simplified geometry. Nonlaminar seepage in the rockfill is described by a turbulent-flow field equation capable of computer solution. The distribution of tractive stress over the bank surface and its dependence on spatially varied discharge is considered.
