Fractional bedload transport in turbid waters
摘要
Abstract
The mechanism of sediment transport in turbid water is different from that in clear water. According to the concept of three states exchange mode of non-uniform sediment at riverbed surface, an analytical formula for calculating the fractional bedload transport rate in turbid was established. In the formula the parameter expressing the drawn up possibility was introduced and the net exchange of bedload towards water flow was considered. The reliability of the proposed formula was verified by experimental and field observation data. It is found that the bedload particles may become coarser than that of original in turbid water. Furthermore, for exactly estimating the sandy bedload transport rate the content of suspended load which comes from bedload should be neglected.关键词
