摘要
对平面二维泥沙数学模型的几个关键问题 :挟沙力系数、恢复饱和系数、床沙级配调整、冲淤厚度和床沙‘归一化’等问题及其相互影响作初步探讨。这种讨论仅限于山区天然河流宽级配河床情况。以上问题在两种底沙不同的河流上应用 。
The present paper gives a discussion about transport coefficient of suspended sediment, coefficient of saturation recovery, riverbed sediment grading, deposition/scour thickness and normalization of the sediment composition in gravel dominantly riverbed. The math model above mentioned has been tested in two rivers with different riverbed sediment composition and a rather good agreement has been obtained.
