What Are Common Levee Failures? What Makes Levees More Susceptible

Question

Examlex · Accepted Answer

The Answer is Common levee failures are caused by bank erosion from river currents or waves,slumps into the channel,or seepage.Water seeping rapidly enough through parts of a levee erodes sediment at the side of the levee,which may then progress until the levee is in danger of failure.Cloudy water seeping out can indicate that soil is being washed out of the levee through a process called piping.Levees can be more susceptible to these types of failures because of their composition from local material.The floodplain materials on which levees are built are often composed of old permeable sand and gravel channels surrounded by less permeable muds.The floodplain muds beyond the current channel are sediments that were left behind by the river where it spilled over a natural levee to flow on the floodplain.
