Relief wells are constructed to provide pressure relief caused by floodwaters at the landward toe of the levee. Excessive pressure at the landward toe of a levee can cause sand boils to develop. When this occurs, levee material moves (called piping). If enough material is piped from the foundation, a direct path can be created, […]
