Abstract: Degraded surface water quality, including harmful algal blooms and associated "dead zones", is a frequent outcome in regions with intensive agricultural land use. The movement of nutrient-rich water and sediments from the land to nearby streams and rivers is facilitated by processes such as erosion and artificial drainage.
