Tony L. Wahl. 2009. "Evaluation of New Models for Simulating Embankment Dam Breach". Bureau of Reclamation, Report Number PAP-999.
Abstract: A consortium of dam owners collaborating through the Dam Safety Interest Group (DSIG) of CEATI, Inc. is evaluating the performance of three embankment dam breach models currently under development. The group is utilizing case-study data from real dam failures and laboratory data from recent large-scale breach tests conducted in USA and Europe. Models are being evaluated for their ability to reproduce observed breach outflow hydrographs and breach geometry, their input data requirements and sensitivity to input data and model parameters, their flexibility for application to a variety of embankment types and failure scenarios, and their overall ease of use and computational requirements. An effort is also underway to evaluate methods for quantifying the erodibility of embankment materials, as erodibility parameters are key inputs to all of the models. The model evaluation process is intended to lead to the selection of modeling technologies that can be integrated with state-ofthe-art dam failure flood routing and inundation analysis tools.
