A numerical model was developed to make spatial and temporal predictions of the water quality for Brewster Lake, located in southwestern Michigan. The model considers the hydrodynamics of the lake, hydrologic conditions, physical, chemical and biochemical processes that take place in the lake, and nutrient loadings from the surrounding watershed. Physical, chemical, and biochemical data collected was used to establish appropriate initial and boundary conditions. In addition, hydrologic data for the region was obtained from three nearby weather stations. COMSOL Multiphysics® was used to solve the resulting integrated complex numerical model and to develop a 2-D graphical model of the lake. The EPA WASP7 water quality simulation program was then used to compare predictions of the different water quality parameters.
