Abstract:
In the present study the numerical modelling aspects of unsteady flow in simple and compound channels are examined through the application to a laboratory data set of the simple hydrologic routing method Muskingum and the unsteady flow dynamic routing models EXTRAN and ONE-D. Model simulations were compared and evaluated by applying various statistical measures to determine the degree of goodness-of-fit between simulated and observed hydrographs. In terms of overall performance, the Muskingum method proved to be a simple and reliable method avoiding complicated mathematical and numerical computations for the cases considered.
