Assessing The Impacts Of Dams On Nutrient And Sediment Loading In The Kalamazoo River Using The Soil And Water Assessment Tool (Swat), Daniel Henry Serfas

Masters Theses

The Soil and Water Assessment Tool (SWAT) was applied to the Kalamazoo River Watershed in order to evaluate the impacts that several dams within a superfund site "Area of Concern" have on the sediment, nutrients, and streamflow of the system. It was hypothesized that the SWAT model could be used to recreate the watershed in hopes of estimating the amounts of nitrogen, phosphorus, and sediment that would result from the removal of the dams. The model would then be used to evaluate dam removal scenarios to come up with a best management practice (BMP).

The model was calibrated, however, during …

Community Response To Habitat Restoration In Sickle And Bear Creeks, With Emphasis On Mottled Sculpin In Sickle Creek, Jason Andrew Deboer

Masters Theses

Habitat restoration is employed by biologists and managers to improve the natural functionality and value of aquatic resources. Systems suffer impairment from many sources, including excessive fine sediment, which negatively affects substrate composition, channel morphology, aquatic invertebrate habitat, and fish reproduction and recruitment. Primary objectives included monitoring the biophysical response to sediment abatement in the Big Manistee River watershed. Secondary objectives included (1) placing the biophysical response to the restoration in the context of a much larger watershed plan, (2) quantifying seasonal mottled sculpin movement and habitat use in Sickle Creek for 1-year, and (3) determining habitat variables which may …
