QUANTIFYING HYDROLOGIC CONNECTIVITY AT THE CONTINENTAL SCALE: INTEGRATION OF BIG-DATA AND IMPLICATIONS FOR MANAGING ECOSYSTEMS
Hydrologic connectivity is defined as the degree to which a system facilitates the transfer of water from source zones to river networks. Quantifying spatial trends in connectivity across large areas, such as continents, is complicated by substantial data requirements and computational demands. In this study, we utilize high-performance computing to calculate the Index of Connectivity (IC) for all 332 HUC-6 basins in the continental United States (CONUS) at 10-m DEM resolution. Results show significant differences in connectivity across CONUS with the most well-connected areas in the Pacific Northwest, Colorado Rockies, and the Appalachian Mountains. Further, typically only 1% or less of a basin area is considered “highly-connected”, which has implications for how limited resources for watershed management should be distributed to maximize ecosystem benefits.
