Erosion, storage, and transport of sediment in two subbasins of the Rio Puerco, New Mexico Erosion, storage, and transport of sediment in two subbasins of the Rio Puerco, New Mexico
Arroyos in the American Southwest proceed through cut-and-fill cycles that operate at centennial to millennial time scales. The geomorphic community has put much effort into understanding the causes of arroyo cutting in the late Quaternary and in the modern record (late 1800s), while little effort has gone into understanding how arroyos fill and the sources of this fill. Here, we...

Science strategy for Core Science Systems in the U.S. Geological Survey, 2013-2023 Science strategy for Core Science Systems in the U.S. Geological Survey, 2013-2023
Core Science Systems is a new mission of the U.S. Geological Survey (USGS) that grew out of the 2007 Science Strategy, “Facing Tomorrow’s Challenges: U.S. Geological Survey Science in the Decade 2007–2017.” This report describes the vision for this USGS mission and outlines a strategy for Core Science Systems to facilitate integrated characterization and understanding of the complex...

Integrated watershed-scale response to climate change for selected basins across the United States Integrated watershed-scale response to climate change for selected basins across the United States
A study by the U.S. Geological Survey (USGS) evaluated the hydrologic response to different projected carbon emission scenarios of the 21st century using a hydrologic simulation model. This study involved five major steps: (1) setup, calibrate and evaluated the Precipitation Runoff Modeling System (PRMS) model in 14 basins across the United States by local USGS personnel; (2) acquire...

Simulations of historical and future trends in snowfall and groundwater recharge for basins draining to Long Island Sound Simulations of historical and future trends in snowfall and groundwater recharge for basins draining to Long Island Sound
A regional watershed model was developed for watersheds contributing to Long Island Sound, including the Connecticut River basin. The study region covers approximately 40 900 km2, extending from a moderate coastal climate zone in the south to a mountainous northern New England climate zone dominated by snowmelt in the north. The input data indicate that precipitation and temperature have...

Description and testing of the Geo Data Portal: Data integration framework and Web processing services for environmental science collaboration Description and testing of the Geo Data Portal: Data integration framework and Web processing services for environmental science collaboration
Interest in sharing interdisciplinary environmental modeling results and related data is increasing among scientists. The U.S. Geological Survey Geo Data Portal project enables data sharing by assembling open-standard Web services into an integrated data retrieval and analysis Web application design methodology that streamlines time-consuming and resource-intensive data management tasks...

Hydrologic effects of urbanization and climate change on the Flint River Basin, Georgia Hydrologic effects of urbanization and climate change on the Flint River Basin, Georgia
The potential effects of long-term urbanization and climate change on the freshwater resources of the Flint River basin were examined by using the Precipitation-Runoff Modeling System (PRMS). PRMS is a deterministic, distributed-parameter watershed model developed to evaluate the effects of various combinations of precipitation, temperature, and land cover on streamflow and multiple...
