Sublevees
Sublevees : Levees that are built for the purpose of underseepage control. Sublevees encircle areas impacted by the main levee that are subject, during high-water stages, to high uplift pressures and possibly the development of sand boils. Sublevees normally tie into the main levees, thus providing a basin that can be flooded during high-water stages. Sublevees are rarely employed as the use of relief wells or seepage berms make them unnecessary except in emergencies
