Abstract: A module adapted to form a protective barrier against liquid runoff or flooding, the module being movable between a working position and a stowed position, including a base adapted to anchor the module to the ground; a retention member mounted to the base to extend vertically relative to the base when the module is in the working position, and extend parallel to the base when the module is in the stowed position; a flexible waterbag fixed to the retention member, wherein the waterbag is supported by the base and adapted to receive liquid passing through an opening of the retention member when the module is in the working position, and the waterbag is contained in the box when the module is in the stowed position.
