Headcut dam
WebDLBreach is a simplified physically-based D am/ L evee Breach model developed by Wu (2013 & 2016). It can simulate the breaching processes of homogenous and composite earthen embankments due to overtopping and piping in inland and coastal contexts. The model uses a one-way breach for inland dam and levee breaching by unidirectional … WebDepending on the depth of the headcut, the headcut can actually undermine pavement leading to a mass wasting of the pavement material as cantilevered section collapse into the headcut. In the case of a concrete dam, the erosion resistance of the foundation rock is typically the key to the likelihood of failure.
