Monitoring temporal and spatial changes provide a way to manage human impact in the environment. This project applied GPS and GIS for landform analysis in the Chualar Creek watershed, to specifically analyze how the dams, located in Chualar Creek, affect landform in the watershed. In doing so, I created a vector map from the GPS points (1999), and compared it to a Digital Elevation Model and to a 1993 Digital Orthophoto Quad map. The results do show in fact, that there is a notable sediment problem occurring upstream and downstream from the dams and that the resolution of the DEM used in this project was too low to be compared to the 1999 data points. Therefore, the 30-meter resolution DEM's cannot be used for purposes such as were tested in this capstone. An interview with Tom Lockhart suggests that a dialog needs to be developed to compromise the needs of both the community members and the natural system of Chualar Creek watershed.
