Description:
This study assesses the water quality impacts of impending future land-use changes in the Little Miami River watershed in southwestern Ohio. By calibrating and validating an integrated watershed hydrological model, the study incorporates the future land-use development plans from the counties comprising the watershed to forecast conditions in the next 10-25 years. Results indicate that the land-use in the watershed shifts, from predominantly rural land-use to a mixed rural and residential land-use. This translates to a reduction in both flow and most species of nonpoint source pollution. Eutrophication in the watershed will most likely result from an overabundance of phosphorus. This information provides information to watershed managers interested in using land-use schemes as mitigation strategies. Our future research proposes to examine the combined and relative impacts of future land-use and climate changes in the watershed.
