Abstract:
1. A water inflatable barrier comprising: a flexible shell configured to contain water in its interior, the shell having a front, a rear, and a substantially uniform cross-section along its width, the cross section being wider at a base of the shell than at a top of the shell; a plurality of water-tight partitions bounded by horizontal and vertical partition walls, each of said vertical partition walls being oriented either substantially parallel to the front of the flexible shell or substantially perpendicular to the front of the flexible shell, said water-tight partitions dividing the interior of the shell into a plurality of adjacent cells having substantially identical dimensions, the cells being shaped approximately as rectangular parallelepipeds arranged in a plurality of horizontal layers that are vertically stacked on top of each other and offset from each other such that none of the vertical partition walls that are parallel to the front of the flexible shell aligns with a vertical partition wall in a vertically adjacent layer, each of widths and lengths of the cells being at least twice as large as heights of the cells; a plurality of vertical openings configured to allow water to flow vertically between the cells; a plurality of horizontal openings configured to allow water to flow horizontally between at least some of the cells; a water inlet proximal to the top of the shell and configured to allow filling of the shell with water; and a water outlet proximal to the base of the shell and configured to allow draining of water from the shell.
