Claim:
1. A device for damming a liquid in a liquid basin, wherein the device, during use, comprises a tubular enclosure suitable for arrangement at an edge of the liquid basin, wherein a longitudinal direction of the tubular enclosure extends substantially parallel to the edge, wherein the enclosure encloses a liquid-fillable space, wherein the enclosure, at an exterior side thereof, facing the liquid basin, includes a skirt for being supported by a sloping underground of the liquid basin, viewed from the edge, wherein the support during use is carried out such that a contact surface present between the skirt and the underground remains substantially free from liquid from the liquid basin, wherein the enclosure, near the lower side of the side during use facing the liquid basin, includes one or more filling openings, arranged contiguous with an intersection of the tubular enclosure and the skirt, that during use create an open liquid connection between the space and the liquid in the liquid basin such that when the liquid reaches the device the tubular enclosure becomes filled through the filling openings, and when the liquid has retreated, the device automatically empties itself, wherein the tubular enclosure is provided with one or more stiffening elements to provide shape retention to the tubular enclosure during use, such that the shape of the tubular enclosure is substantially maintained during filling and emptying of the device, and wherein a skirt anchor extends continuously along a free end of the skirt to provide a seal between the skirt and the underground.
