A Water-meadow (also water meadow or watermeadow) is an area of grassland subject to controlled irrigation to increase agricultural productivity. WAter-meadows were mainly used in Europe from the 16th to the early 20th centuries. WOrking water-meadows have now largely disappeared, but the field patterns and water channels of derelict water-meadows remain common in areas where they were used, such as parts of Italy, Switzerland and England. DErelict water-meadows are often of importance as wetland wildlife habitats. WAter-meadows should not be confused with flood-meadows, which are naturally covered in shallow water by seasonal flooding from a river. "Water-meadow" is sometimes used more loosely to mean any level grassland beside a river.
