Evaluation of Methods for Predicting Bend Loss in Meandering Channels
Publisher: American Society of Civil Engineers
Abstract: The resistance to flow of a channel is increased significantly by the presence of bends or curves. Existing methods for predicting stage‐discharge relationships for meandering channels give conflicting results and none ...
Experimental Study of Bed Load Transport through Emergent Vegetation
Publisher: American Society of Civil Engineers
Abstract: Vegetation is an important agent in fluvial geomorphology and sedimentary processes, through its influence on the local hydraulics that determine sediment transport. Within stands of emergent vegetation, bed shear is ...
Modes of Bed-Load Movement on a Smooth Rigid Surface
Publisher: American Society of Civil Engineers
Abstract: Sediment grains transported as supply-limited bed load on a rigid surface move either discretely or collectively as bed forms, with significantly different effective grain speeds and active storage volumes. The adopted ...
Onset of Skimming Flow on Stepped Spillways
