SAND TRANSPORT DURING CLOSURE OP TIDAL CHANNELS

J.N. Svasek, J.H.J. Terwindt, A.W. Walther

Abstract


A method is presented for estimating the dredger capacity required for closing tidal gaps with sand as the only building material. The method is based essentially on a relation between parameters describing the flow of the water and the resulting sand transport. Empirically determined coefficients are used to approximate the effects of the non-stationary flow in the gap and the supply of suspended material at the dumping site. The experiences gained at a number of closure operations are discussed and compared with the computations.
