Historical Landscapes and Mans Influence on Soils How does a Water Meadow work? By definition a water meadow is an area of pasture, near a river, which is deliberately flooded or 'drowned' to encourage the growth of grass or crops. This extracted water deposits any nutrients from the river in the land and so stimulating the growth of vegetation by increasing the fertility. In broad terms this enables the early production of animal fodder and an increased annual yield. The 'bedwork' for a water meadow is usually located on alluvial soils of the floodplain where water is directed from a main river, by a canal ('main carrier') through a series of weirs, hatches, or sluices which act as restraining structures. The rich sediment flow is then focused into narrowing channels that spill down the sides of specially constructed ridges. This system is a very complex method of increasing soil fertility...
