A levee apparatus and system for impeding and controlling the flow of fluids, primarily the flow of water as experienced in a flood or storm surge consisting of a light weight concrete structure with reinforcing steel rebar depending on the application. It is constructed from prefabricated sections with the tongue and groove ends designed to fit together which, when used in conjunction with a rubber gasket, will produce a water tight seal. The structure would be hollow with an opening along the unprotected face to provide a location for the surge water to enter. The structure would have flap-gates on the protected side and on the unprotected side. This would allow flood waters from the protected side to push open the flap-gate and exit the protected side based on the pressure equalization of the flood waters. Once inside the structure any water would then drain from the structure through the flap-gate on the unprotected side when the surge water diminishes. The structure could be placed simply on top of the existing soils or anchored in place to prevent potential changes in alignment. Two main modifications to this design include utilization of a rubberized base which would allow the top portion of the structure to rise into position, and the adjustment of the flap-gate position to change the use of the structure from solely a flood protection system to a retention control system.
