Deposition and Transport Processes of Suspended Load on a Channel Bed with a Large Porosity

Abstract

In this paper, deposition and transport processes of suspended load on a channel bed with a large porosity are discussed. These processes might be observed in mountain rivers, particularly in deposition areas of debris flow. In such a field, suspended load would fall into the bed layer and its transport rate would decrease in the streamwise direction. With an attention focussed on the difference of the deposition processes due to the geometrical size of the porosity, the deposition and transport processes are investi-gated experimentaly and its numerical model is presented.
