Critical Velocity Ratio for Silt Grades
The critical velocity ratio is an essential parameter in sediment transport, particularly in the design of irrigation channels and canals. It helps in understanding the sediment-carrying capacity of a flow based on the type of silt present. For different grades of silt, the critical velocity ratio varies and is crucial for preventing sediment deposition or erosion.
