Abstract: The most common bedload transport calculation methods use an equation for the vector direction that is a linear function of the transverse slope. Existing theoretical formulations that account for nonlinear effects when ...

Abstract: An analytical model is developed for unidirectional-flow waterways in which the dissolved oxygen (DO) mass balance is dominated by reaeration and sediment oxygen demand (SOD) fluxes. To accurately represent the feedback ...

Abstract: Sediment oxygen demand (SOD) can be a significant oxygen sink in various types of water bodies, particularly slow-moving waters with substantial organic sediment accumulation. In most settings in which SOD is a concern, ...
