Low Head Dams are man-made structures that span the width of a river and allow water to flow over them. Although these structures vary in age and original purpose, some pose a life-threatening danger when recreationalists are entrapped in the reverse current at the toe. Despite these dangerous structures causing many drowning deaths in the USA each year, most low head dams do not have safety regulations and remain unknown to those charged with dam and public safety. Thus, to improve public safety at these structures, the first step is to fully inventory low head dams, so that subsequent efforts …

Backward Erosion Piping (BEP) is an internal erosion mechanism which occurs at the down stream of dams or levees. Two conditions needed for this failure to occur: 1) head of water in the upstream of the dam or the levee to drive the seepage forces, and 2) crack in the roof or the blanket layer of the cohesionless material in the downstream of the dam or a levee. Numerous researches were performed in the past in an attempt to predict the critical gradient for BEP to initiate. Some researches are too conservative and other researches are under predicting the critical …
