Book Description
This report described procedures necessary to calculate and route a dam-break flood using an existing generalized unsteady open channel flow model. The recent Teton Dam event was reconstituted to test the model's performance on such a highly dynamic wave. The procedures outlined relate, primarily, to partial breaches. Some deficiencies in the model were identified which will require some further research and programming to improve the applicability of the program to dam-break flood events. The special project memo established four objectives for this study. The first two, (1) level of accuracy of existing techniques and (2) sensitivity of calculated results to n-values and breach size, were summarized and presented in detail in Appendix A. The third objective, (3) description of physical phenomena controlling depth and travel time and a discussion of pertinent field data was presented in the body of this report. The fourth objective, (4) documentation of the methodology, was included in Appendix B. Computer programs utilized in the methodology may be obtained from The Hydrologic Engineering Center. The computer program was applied to the Teton Dam data set to demonstrate the level of accuracy one might expect in such analyses. The results were shown and, in general, appear reasonable. (Author).

A Two-Dimensional Flood Routing Calculation

Languages : en
Pages : 18
Book Description
The desirability of accurately predicting the extent and duration of flooding resulting from the partial or total breach of a dam has been emphasized recently. The most practical way to meet this need is the development and use of good computer-based models. In order to predict the routing of floods, several hydrograph routing and one-dimensional models have recently been developed. Among the better known models are those employed in the code DAMBRK, Fread (1980) and in HEC-1 (1973). These models have proved to be quite good in predicting the flooding in those cases which have been amenable to a one-dimensional treatment. The accuracy of these models in situations which are clearly two-dimensional in nature is suspect, however. It is thus desirable to develop two-dimensional flood routing models to properly handle those situations in which the one-dimensional models are inadequate. Energy Incorporated (EI) has developed a computer code, FLOOD, that describes the two-dimensional motion of a flood. An analysis of the hypothetical Mackay Dam failure was performed using FLOOD. In this paper are given the equations used by EI, the numerical algorithm used for their solution, and the results of the Mackay Dam analysis.
