A sensitivity analysis of groundwater-recharge estimates from a water-budget model was completed for the islands of Oahu and Maui, Hawaii (Johnson and others, 2023). Results of the sensitivity analysis were used to quantify the relative importance of selected model parameters to recharge estimates for three moisture zones (dry, mesic, and wet) on Oahu and Maui. This shapefile contains the boundaries of the moisture zones and boundaries of the model subareas that were used in the model simulations for Oahu. The shapefile attribute information includes the names of the land-cover types assigned to model subareas and the mean annual recharge values determined for the model subareas for the baseline scenario of the...

The Little Sequatchie River and Pryor Cove Creek watersheds are located in southern Tennessee and drain the eastern escarpment of the Cumberland Plateau to the Sequatchie River. The Little Sequatchie River has the largest drainage area of any Sequatchie River tributary, with over 130 square miles in the topographic confines of the watershed. The hydrology of both watersheds has been largely altered by karst processes which have caused the majority of the streams to sink into the sub-surface, typically at the contact between the Mississippian Pennington Formation and the underlying Mississippian Bangor Limestone. A collaborative project between the U.S. Geological Survey and the U.S. Fish and Wildlife Service began...

This data set contains mean annual recharge due to infiltration of precipitation, in inches (x 1000), within the upper Umatilla River Basin, Oregon, for calendar years 1981 - 2010. Recharge due to infiltration of precipitation is estimated using a regression method developed by Bauer and Vaccaro (1990) that relates annual recharge to annual precipitation. Gridded mean annual precipitation for years 1981 - 2010 was provided by the Oregon State University PRISM Climate Group.

Current land use practices have affected ecosystem structure and processes in ways that have degraded delivery of key ecosystem services controlling exchanges of carbon and nitrogen with the atmosphere and surface and groundwater systems. These impacts are observed in the emissions of greenhouse gases (GHG) and N pollution in our nation’s water systems and coastal areas. Improvements in databases of climate, soils, and land use practices in the north central Great Plains (i.e., NCGP: Colorado, Kansas, Wyoming, Nebraska, Montana, South Dakota, and North Dakota) provide a unique opportunity for integration and synthesis of this information on the exchanges of C and N affecting our environmental resources. In addition,...
