Abstract: Provided is a flood protection system for protecting an area from flooding water, wherein the area includes a trench defined at least along a portion of the boundaries thereof and a at least one depression on the side of the trench facing away from the area to be protected. The system comprising a barrier, configured for being at least partially fitted in the trench; and a float coupled to the barrier and being configured for at least partially is disposed in the depression. The float is configured for rising in response to a rise in the water level inside the depression and about the boundaries of the area. The float is further configured for lifting the barrier out of the trench therewith, thereby blocking the waters from entering the area.
