Dangers of hydraulic jumps
WebSubmerged hydraulic jumps create the dangerous current that drowns roughly 50 recreationists each year, and high tailwater is a key element in its formation. Using a simplified approach based on ... Webdownstream tailwater elevation, creating a hydraulic vortex at the base of the dam with strong upstream-directed currents along the surface of the water. Entrained air within the jump adds to the danger by changing buoyant conditions in the jump, making it harder for objects to remain afloat. This hydraulic condition is commonly referred to as ...
