1. A flood control system, comprising a substantially rigid exterior shell erectable into a desired shape and a flexible bladder having a corresponding shape when filled with a fluid and including one or more valves for introducing and removing a desired amount of fluid to and from the bladder, the shell having a length and including opposite first and second rigid sides hingedly connected to one another to permit the shell to be positioned in a desired orientation exterior to and substantially overlying the flexible bladder, with the bladder having a length that is greater than the length of the shell and sufficient to enable the bladders of adjacent systems to bear against one another to substantially seal the interface against passage of flood water. 2. The system of claim 1, wherein the shell is of one-piece molded plastic construction. 3. The system of claim 1, wherein the shell is erectable into a substantially triangular configuration and the bladder is substantially triangular in configuration when filled with fluid. 4. The system of claim 1, wherein the shell includes an aperture configured and positioned to receive one of the valves of the bladder. 5. The system of claim 4, wherein the valve includes a pair of straps and the aperture of the shell includes slots for receiving the straps for securing the valve adjacent the aperture of the shell. 6. A flood control system, comprising a substantially rigid exterior shell erectable into a desired shape and a flexible bladder having a corresponding shape when filled with a fluid and including one or more valves for introducing and removing a desired amount of fluid to and from the bladder, wherein the valve includes a pair of straps and the aperture of the shell includes slots for receiving the straps for securing the valve adjacent the aperture of the shell and the shell includes opposite first and second rigid sides hingedly connected to one another to permit the shell to be positioned in a desired orientation exterior to and substantially overlying the flexible bladder.
