Equilibrium of alluvial streams has been thoroughly studied in the past century. Many investigators have extended analysis to explain meandering (or braiding) of streams, and attempted to describe the hydraulic geometry of alluvial streams. This study points at the derivation of the characteristics of alluvial streams from fundamental principles. More precisely, this research aims to determine the downstream geometry of alluvial streams (channel width,...

Soil erosion by rainfall is one of the major sources of sediments transported into streams. The physical processes governing rainfall erosion are very complex and no generally accepted sediment transport equation has been developed so far. Various approaches have been used in the past decades to analyze sediment transport by overland flow.
