Some notes on Muskingum method of flood routing

The Muskingum method of flood routing is revisited. A survey of literature indicates that the initial condition proposed by Gill is incompatible with the Muskingum hypothesis, that the translatory characteristics later derived by Gill are based on unrealistic assumptions, and that the assumptions made by Kulandaiswamy are also unrealistic. These issues are examined in this paper. Further, five different methods of parameter estimation are compared for three sets of data reported in the literature and are found to be comparable.
