A Model Study on the Role of Wetland Zones in Lake Eutrophication and Restoration
The Scientific World Journal, 2001 Shallow lakes respond in different ways to changes in nutrient loading (nitrogen, phosphorus). These lakes may be in two different states: turbid, dominated by phytoplankton, and clear, dominated by submerged macrophytes. Both states are self-stabilizing;
