Uncertainty Analysis of Earthen Embankment Dams

摘要

WindowsTM Dam Analysis Modules (WinDAM) is a set of modular software components that can be used to analyze overtopped earthen embankments and internal erosion of embankment dams. These software components are being developed in stages. The initial computational modules address routing of floods through the reservoir with dam overtopping and evaluation of the potential for vegetation or riprap to delay or prevent failure of the embankment. Subsequent modules incorporate dam breach analysis. Current work is underway to include analysis of internal erosion, non-homogeneous, zoned embankments, and the analysis of various other forms of embankment protection. The focus of this paper is on the overall software architecture and its integration with Sandia National Laboratories' DAKOTA software suite to conduct parameter studies and uncertainty analysis on a range of input parameters.
