水沙交界面冲刷与淤积的同步性探讨
A Study on the Mutually Exclusive of Erosion and Deposition at the Water-sediment Interface
摘要
Abstract
During the exchange process of suspended sediment and bed sediment,whether the suspended sediment deposits when erosion occurs? It's very important to understand the sediment flux at the water-sand interface,so the process of erosion and deposition deserves further exploration.This article analyzed and summarized several series of experiments,including the classic Krone,Mehta,Partheniades and other experiments.Based on the several different formulations of the sediment flux near bed,the process of erosion and deposition was analyzed.Combined some analyses at the estuary and bay,it concluded that the erosion and deposition occurred simultaneous at the water-sediment interface for both non-cohesive and cohesive sediment.The resuspension process was used to explain the simultaneous occurrence of fine sediment flushing and sedimentation processe,thus further perfecting the physical map of sediment exchange in the near-end sediment.关键词
