| Abstract | Motion of turbidity clouds propagating horizontally along the bottom boundary, that produced by instantaneous release of turbid water from water surface into a quiescent fresh water, is investigated experimentally. A series of laboratory experiment is conducted by varying inflow condition as well as ambient water depth. The motion of turbidity clouds is found to be distinguishied into two flow regions: the transition and gravity current region. The nondimensional parameter to describe the motion of the flow in each region is quantified. Such relationships as height, average buoyancy and propagation speed of the clouds in the gravity current region are quantified as well. |
