Longshore wave
WebThe most widely used formula for longshore transport (LT) is the CERC equation (Shore Protection Manual, US Army Corps of Engineers, 1984). This method is based on the principle that the longshore transport rate (LT, incl. bed load and suspended load) is proportional to longshore wave power P per unit length of beach; LT=K P, with … WebSubscribe 17K views 2 years ago Longshore Drift which is also called littoral Drift involves the movement of sand and other items along the shoreline.
