Abstract
 Functional Linkage of Watersheds and Streams: ArcGIS FLoWS Tools Track: Water Resources Author(s): David Theobald, Erin Peterson, Silvio Ferraz, John Norman Landscape or watershed metrics are needed to support statistical analyses of aquatic resources, particularly to examine the possible consequences of land use change water quality. A key to a better understanding of these linkages is a stronger representation of hydrologic and ecological processes that improves spatially-explicit watershed analysis. We have built a series of ArcGIS 9 tools (written in Python) designed to process common datasets such as USGS National Hydrography and National Elevation Datasets to generate a framework of reach contributing areas, to conduct common analyses and queries based on stream networks and to export a variety of hydrological distance matrices useful for regression and geostatistical analyses.
