Abstract
The problem of hydrodynamic loads arising from the interaction of gravity currents with an obstacle on the channel bottom was studied experimentally. The gravity-current structure was visualized at the stage of formation and at the stage of interaction with the obstacle. The dependence of the propagation velocity of the gravity-current front on the nondimensional current depth and the Archimedes number was studied. In the region of self-similarity in the Archimedes number, the behavior of hydrodynamic-load coefficients was studied as a function of the nondimensional gravity current depth.
