Dependence Of Hydrological Modeling On Spatial Resolution In Lake Whatcom Watershed, Emily Mcginty

Scholars Week

Remotely sensed digital elevation data can be utilized through geographic information science (GIS) techniques to model watershed and stream delineations. These techniques allow analysts to easily produce results that would otherwise require hours of intense field work, if possible at all. The accuracy of these watershed and stream models can be dependent on the resolution of the elevation data, and choosing an inappropriate resolution can result in further analyses producing inaccurate and/or misleading results. The purpose of my research is to quantify the differences between hydrological models developed from elevation data at varying resolutions. I chose the Lake Whatcom watershed …
