The environmental impacts of agriculture and urbanization in the form of population dispersals from cities into more rural areas can be determined by assessing changes in water quality with respect to land use/land cover changes over a period of time.

The North Crooked Creek watershed is predominately rural but contains the village of New Concord which has a population of about 2700 (the population rises to approximately 4300 during the academic year). GIS analysis of topographic maps and aerial photographs spanning the years 1961-2004 allow for quantifying/determining any land use/land cover changes [...]
