WebWhat is scouring in Canal? Hydrodynamic scour is the removal of sediment such as silt, sand and gravel from around the base of obstructions to the flow in the sea, rivers and canals. Scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure. WebDec 1, 2013 · Scouring is initiated at the nose of the piers or at the sharp bends. Estimation of scour depth is very important for the design of foundation for abutment or pier. Scouring compromises the structural integrity and thus causes failure of the structure. It has been estimated that over 60 % of the highway bridges are being collapsed due to scouring.
