Hindered Settling of Silt
Publisher: American Society of Civil Engineers
Abstract: Sediment particles smaller than 64 μm, with a noncohesive base mineral, are referred to as silt. The settling velocity of suspended sediment decreases with increasing concentration due to hindered settling effects. Compared ...
Long-Term Effects of Water Diversions on the Longitudinal Flow and Bed Profiles
Publisher: American Society of Civil Engineers
Abstract: Water diversions along alluvial rivers cause water and sediment loss, and thereby affect morphological development. Assuming spatially continuous diversions along a constant-width channel, previous studies suggest a ...
Groyne-Induced Effects on Channel-Shoal Exchange and Saltwater Intrusion in Estuarine Environments
Publisher: ASCE
Abstract: Existing knowledge about groyne-induced effects is primarily based on riverine or coastal environments where salinity gradients are absent or limited. However, in estuaries, salinity gradients drive physical processes such ...
Critical Bed-Shear Stress of Mud–Sand Mixtures
Publisher: American Society of Civil Engineers
Abstract: The critical bed-shear stress (cbs) for erosion of mud–sand bed mixtures was studied in laboratory and field conditions with currents, waves, and combined currents and waves. Three types of erosion were distinguished: ...
