Abstract |
A simulation model of an open channel system was used to evaluate some existing flood routing methods, observe the effect of different physical variables on flood wave movement, and to develop a simple routing method. The physical, geometric, and hydraulic components of the model were patterned after real-life conditions common to southeastern Minnesota. The dynamic equations of unsteady flow were used to route flood hydrographs through the channel system and outflow hydrographs were generated to achieve the objectives. The method of characteristics with a specified time interval was used to solve the unsteady flow equations. Two simple storage routing methods were developed and evaluated. Other simple routing methods evaluated include: the Miskingum, the Puls, and the Kinematic Wave. (Author) |
