Abstract:

Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods are compared for spillway analysis and for dam failure analysis. A hypothetical reservoir, in the shape of a truncated pyramid, with variable dimensions is used to compare the routing methods. Test results, based upon the hypothetical reservoirs, are used to develop criteria for determining if dynamic routing should be used for a particular reservoir. Dam safety analysis case studies for several reservoirs in Missouri are performed to test the validity of the criteria developed. The National Weather Service computer model DAMBRK is used to perform all routing computations.
