COMPARISON OF GEOMORPHIC PROPERTIES BETWEEN FUNCTIONAL PROCESS ZONES IN THE WESTERN UNITED STATES
From a watershed and stream management perspective, functional process zones (FPZs) are potentially a way for ecosystem and watershed managers to identify specific river reaches based on research interest or project needs. For this study, FPZs were classified and mapped along three rivers in the Great Basin and Bighorn Mountains (USA) using a GIS protocol. River reaches within the resulting FPZs were sampled based on the modified EMAP protocol to test whether significant hydrogeomorphic differences existed across scales, including between FPZs, within a single river basin, and among river basins in the Great Basin and Bighorn regions and between regions. Our study reveals both a substantial amount of internal complexity among FPZs within a river and consistency in the morphological nature of FPZs between rivers within an ecoregion. From a watershed management perspective, the ability to predict hydrogeomorphic processes at the watershed scale is beneficial for cost-effective and standardized management and research goals. From a macro-ecological perspective, this analysis reveals how aggregation of data at larger spatial extents can illuminate patterns that might otherwise be obscured by limiting analyses to finer scales.
