Abstract

Thousands of miles of levees exist in the United States and around the world and failure of these levees as a result of breaching has the potential to cause severe flooding damage. A technology, the PLUG, has been developed to temporarily reduce the flow through a levee breach as an alternative to traditional methods. This study is focused on developing initial guidance on the parameters for sizing a PLUG using a 1:100 (model:prototype) Froude scaled model. It was found that for the PLUG to effectively reduce flow through the breach, the required ratio of the PLUG length to the breach width is greater than two (L/W > 2), and that effectiveness increases as the ratio between the PLUG diameter and water depth (D/d) increases. Effectiveness also increases when the percent fill (P) is between 65 – 75 percent. Trends in the threshold between catastrophic failure and success were also noted.
