A modular component dam. The dam may be configured for pairing with another dam in the form of a closed loop pumped storage hydropower plant. One or both of the dams may be constructed of buttress frames made up of prefabricated modules of predetermined varying dimensions which allow for rapid construction over a period of less than about a year. The modules may be transported to dam sites by standard transportation units such as 18 wheelers. This is facilitated by the modules occupying no more than about 14 feet in vertical height above a surface of a roadway during transport and no more than about 11 feet in horizontal width across the roadway during transport.

A flood protection system including a tube plate assembly including a plurality of orifices arranged in a predetermined pattern and density. A tube attachment subsystem is associated with each of the plurality of orifices and is configured to secure an open ended independent barrier tube thereto. A plurality of spaced walls are configured to support the tube plate assembly above the ground such that each barrier tube extends vertically downward from the tube plate to the ground. Filling each barrier tube with the fluid provides outward hydrostatic pressure at each tube-to-tube interface such that friction loss of a flow of flood water along each barrier tube-to-tube interface pathway stops the ingress of the flood water from a flood area to a protected area.

Flood control apparatus are disclosed. In one aspect, a flood control apparatus includes a structural frame. The structural frame has an elongated length in a longitudinal direction. The structural frame includes a plurality of transverse support structures, that are generally aligned in the transverse direction, and that are spaced apart in the longitudinal direction. The structural frame includes one or more longitudinal coupling structures that couple the plurality of transverse support structures together. One or more sheets of material are coupled to the structural frame. When in use, earth may be used to substantially fill an inner region of the apparatus that is enclosed by the one or more sheets of material coupled to the structural frame.
