The determination of bed shear stress plays a pivotal role in understanding the fluid dynamics in both natural and engineered channels. The commonly employed logarithmic law provides a mathematical formula to compute the bed shear stress in open-channel flows. However, its applicability in flow through...

Two-dimensional, depth-averaged flow models are used to study the distribution of flow around spill-through abutments situated on floodplains in compound channels and rectangular channels (flow on very wide floodplains may be treated as rectangular channels). The study leads to useful insights regarding...
