A Hydraulic Friction Model for One-Dimensional Unsteady Channel Flows with Experimental Demonstration

A Hydraulic Friction Model for One-Dimensional Unsteady Channel Flows with Experimental Demonstration

As a critical parameter of the steady uniform friction model, the roughness coefficient changes with flow unsteadiness in flood events; i.e., the flow conditions of the stream segment significantly affect the flow resistance. In this study, a modified formula was established to improve the unsteady...
