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

Rock chutes, rock riprap on steep slopes, are used as grade control structures to safely conduct a water flow to a lower elevation. Previous studies have reported relationships to predict the highest stable unit discharge on the sloping face as a fun

A hot-film anemometer was used to obtain hydraulic shear stress measurements on the boundary of a fixedbed channel. These boundary stresses were measured upstream of an overfall brink for approach flow Froude numbers ranging between 1 and 4. The time

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 assessment of the erodibility of soil materials is essential for analyzing and modeling rill, gully, streambed, streambank, spillway, and embankment erosion. A submerged jet-testing apparatus has been developed and used for characterizing soil er

Two– and three – dimensional analysis using close–range digital photographs can be very useful in measuring changes in erosion on the landscape. Computer software exists for conducting photographic analysis but it is often either cost prohibiti

Scour below an overfall contributes to headcut instability and gully advance. Thirteen large–scale scour tests were conducted by preforming an overfall in a compacted cohesive soil bed. Horizontally compacted soil layers were placed using typical e
