Abstract:

Under a contract with the Federal Highway Administration and Bureau of Reclamation, Simons, Li & Associates, Inc. (SLA) is conducting an overtopping damage study to evaluate various embankment protection measures. Full-scale hydraulic tests are being conducted using a 4 feet wide, 11 feet high, and 85 feet long flume with a discharge capacity of 100 cfs. Protection measures tested include gabion, Geoweb, soil cement, Enkamat, and cable-tied concrete blocks. The test results are analyzed along with field data and other research results to assess erosion damage of soil embankments due to flood overtopping, and to develop quantitative design criteria for protecting highway and dam embankments.
