Abstract: Research has shown that improved drainage increases peak runoff rates and pollutant loads compared to natural conditions. However improved drainage on agricultural lands may reduce outflow rates while decreasing losses of some pollutants and increasing the losses of others. A summary of research on hydrologic and water quality effects of agricultural drainage is given in this paper.
