Abstract

The prediction of how an embankment dam or flood levee may erode, and ultimately breach, is fundamental to identifying and managing flood risk in partnership with cost effective asset management. Flood risk analyses, built upon levee and dam breach predictions, may underpin emergency action plans, critical infrastructure performance and land use planning. Research over the past decade or so combining large scale field testing, breach model development and validation has tended to focus on the performance of finer, cohesive materials with a reasonable understanding and prediction of head cut processes developing. However, not all dams and levees are constructed from the ideal grading of fine and cohesive materials, with some containing worrying amounts of coarser non cohesive material. This poster outlines research conducted by EDF, HR Wallingford, and the U.S. Army Engineer and Development Center (ERDC) that plans to investigate the erosion performance of coarser grained materials found in dams and levees, looking at both macro and micro scale processes, and allowing for breach model development and validation to complement the earlier research and model validation for finer more cohesive materials.
