Transport Phenomena on The Landscape: Lateral Connectivity And Fluvial Sediment Transport

Abstract

sediment transport as bedload and suspended sediment is linked to rainfall-runoff and water erosion on watershed hillslopes. Therefore, the connectivity between the sediment transport phenomenon in watershed hillslopes and sediment transport rates in rivers may link issues such as lateral flow to resistance to the water surface, generating impedance/resistance to lateral sediment transport on hillslopes. This research was conducted to determine the suspended sediment transport from hillslopes from three Brazilian watersheds and address their curve number values to address this idea. The lateral sediment transport constituted by suspended sediment being detached and transported on the hillslopes was a linear adjustment to the watershed CN values. Additionally, the linear relationships among the amount of suspended sediment added to the bedload, and shear stress were successfully applied here to achieve soil erodibility at the watershed scale.
