Experimental study of flow resistance and bed load transport of bed material with discontinuous wide-gradation sediment by clear water scouring( Ⅱ )——Bed load transport law
摘要
Abstract
Flume experiments of bed load transport by clear water scouring were carried out for the discontinuous wide-gradation sediment that widely exists in natural rivers. According to the flume experiment data of steady clear water scouring, the decay law of bed load transport rate, bed load size distribution and calculation of bed load transport rate are analyzed. A series of transport law of discontinuous wide-gradation sediment bed by clear water scouring are obtained and the relation of discontinuous and continuous wide-gradation sediment is revealed, those provide the basis for the research about discontinuous wide-gradation sediment.关键词
