Estimates Of Discharge Coefficient In Levee Breach Under Two Different Approach Flow Types, Seung Oh Lee, Kwang Seok Yoon, Jun Seon Lee, Seung Ho Hong

Faculty & Staff Scholarship

The amount of released water (discharge) in a levee breach is a primary input variable to establish an emergency action plan for the area next to the levee. However, although several studies have been conducted, there is still no widely applicable discharge coefficient formula; this needs to be known to estimate discharge amount through an opening caused by a levee breach. Sometimes, the discharge coefficient developed for a sharp crested side weir is used to rate the discharge, but, in case of a levee breach, the resulting geometry and flow types are similar to that over a broad crested weir. …
