Spatially Distributed Surface--Subsurface Watershed Hydrology Model ofWater and Materials Runoff

Sediment, waste, pesticide, and nutrient loadings to surface and  subsurface waters can result in oxygen depletion and eutrophication in  receiving lakes, as well as secondary impacts such as harmful algal  blooms. This project is conducting material surveys on pollutants such  as animal manure, soils, fertilizers, insecticides, and Combined Sewer  Overflows (CSOs), which can contribute excessive nutrients into  Saginaw Bay and other watershed in Michigan, and have the potential of  triggering harmful algal blooms. All four watersheds in Saginaw Bay  have been modeled. The project will develop an integrated, spatially  distributed, physically-based water quality model to evaluate both  agricultural non-point source loadings from soil erosion, animal  manure, and pesticides, and point source loadings at the watershed  level. This research aids natural resource managers in understanding  and identifying the movement of point and non-point source pollutants  into waterbodies, and will effective management of pollution at the  watershed scale.    (Michigan); (eutrophication); (algal blooms); (algae); (harmful algal  blooms); (algal bloom); (harmful algal bloom); (beach monitoring);  (monitoring); (hypoxia); (pollution); (pollution movement);  (microbial); (microbes); (microbe); (point source contamination)
