SITE INVESTIGATION ON SAND CONCENTRATION IN THE SHEETFLOW LAYER

Z. Yu, H.D. Niemeyer, W.T. Bakker

Abstract


Field measurements of sand concentration in the sheetflow layer have been carried out in the swash zone on a beach on the island of Norderney. Simultaneous registration of both sediment concentration at three levels and the velocity of wave induced water movement in the boundary layer gives an impression of the phenomenon sheetflow for prototype conditions.
