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.
