Seepage, Slope and Settlement for Levees

The Seepage, Slope and Settlement for Levees online PDH course is a part of the Civil Engineering category of courses. This course will introduce you to methods for controlling seepage and settlement in the construction of levees, and to generally acceptable guidelines for levee slopes. Without control, underseepage in pervious foundations beneath levees may result in (a) excessive hydrostatic pressures beneath an impervious top stratum on the landside, (b) sand boils, and (c) piping beneath the levee itself. Underseepage problems are most acute where a pervious substratum underlies a levee and extends both landward and riverward of the levee and where a relatively thin top stratum exists on the landside of the levee. Principal seepage control measures for foundation underseepage are (a) cutoff trenches, (b) riverside impervious blankets, (c) landside seepage berms, (d) pervious toe trenches, and (e) pressure relief wells.

After completion of this course you will have a basic understand of the construction of slope, settlement and seepage issues that need to be addressed when designing and constructing levees.

This course is intended for civil engineers and other professional engineers and construction managers wanting an introduction to the design and construction of levees.
