Muskingum Method with Variable Parameters for Flood Routing in Channels

摘要

Three versions of the Muskingum method with variable parameters for flood routingin open channels were derived. The reach travel time was obtained from simplification of the St. Venant equations. The three versions were applied to three example data sets and the results obtained were found to he more accurate than those of the conventional Muskingum method with parameters obtained by trial and error or optimization.
