Overtopping, internal erosion, and piping are the main causes of accidents and failures of embankments for dams, lagoons, and levees. A key parameter in the failure of these structures is the erodibility of the soil materials used in construction of

The Small Watershed Program, administered by the USDA Natural Resources Conservation Service (formerly the Soil Conservation Service), originated in the 1940s and 1950s through the following statutes: the Flood Control Act of 1944, the pilot watershe

The formation process and timing of a dam embankment breach caused by flood overtopping can dramatically impact the rate at which water is released from a reservoir and directly impacts the hazard to life and property downstream of a breached dam. Th

In recent years, interest has risen in the occurrence and effects of overtopping on earth embankments due to the number of dams that have reached the end of their planned service life. The embankment failure process due to overtopping includes severa

The erosion rate of cohesive soils is typically computed using an excess shear stress model based on the applied fluvial shear stress. However, no mechanistic approaches are available for incorporating additional forces, such as groundwater seepage i

Predicting headcut migration is a complex problem. The rate of headcut migration is of specific interest for engineers designing earthen spillways and embankments. Headcut migration tests of a compacted soil were conducted in a 1.8-m wide and 29-m lo

The objective of this study was to investigate the potential of using ultrasonic immersion testing as a simple procedure to identify and quantify the effects of immersion on a compacted soil. Preliminary tests were made on a soil compacted at various
