A flexible water gate is described that is suitable for retaining water in a port, canal or river estuary. The gate is both economical to build and maintain and comprises a gate control means that allows a flexible membrane to be controllably moved between a closed and open position as required. A flexible flood control barrier that comprises one or more of the aforementioned flexible water gates.
