Abstract

Soon after a large storm causes significant precipitation over a land area, the runoff from the storm begins collecting in streams and rivers creating a flood wave. As the flood wave travels downstream, its characteristics have been predicted and its impact studied. This prior knowledge of the flood wave is based on mathematical models that are able to calculate the magnitude, duration, velocity, water surface level, and numerous other parameters of flood waves. The evaluation of the modified Puls flood routing approach as developed and applied by the U.S. Army Corps of Engineers (Corps) is performed in this study. This study uses two software programs developed by the Corps to execute the modified Puls approach and a third software program developed in The Netherlands to provide a solution to the de Saint Venant equations for comparison to and evaluation of the modified Puls approach. Laboratory data are used along with simulation results for hypothetical case studies from textbooks. The results presented offer a range of case studies where the modified Puls flood routing approach developed by the Corps is valid. The modified Puls flood routing approach performed well in all of the evaluated case studies, and in several cases, additional routing steps provided little appreciable improvement in performance.
