Abstract

This paper is concerned with the prediction method of sedimentation process in reservoirs.The contribution of suspended load, which having been treated empirically, is considered theoret-ically and found to be propotional to the discrepancy between the actual concentration and the equi-librium concentration just above the river bed. A practical method to estimate the longitudinaldistribution of the former is proposed and its applicability is verified through numerical investigations.The fundamental equations for the evaluation of the bed-profile deformation and the change ingrain-size distribution are given after dividing the whole region of reservoir into three sub-regionsarranged in a row.
