Percent change in the average surface runoff for each HUC5 watershed between historical (1971-2000) and future (2071-2100) time periods. The MC1 dynamic vegetation model was run under the CSIRO, MIROC, and Hadley climate change projections and the A2 anthropogenic emissions scenario.Simulated mean annual surface runoff (in mm H2O yr-1), was determined for each HUC5 watershed by averaging values of original ~ 4 km raster data. Watersheds represent 5th level (HUC5, 10-digit) hydrologic unit boundaries and were acquired from the Natural Resources Conservation Service. Background: The dynamic global vegetation model MC1 (see Bachelet et al. 2001) was used to simulate vegetation dynamics, associated carbon and nitrogen...

The Middle East and North Africa (MENA) region is the most water-scarce region with only two percent of the global average annual rainfall, hence underground aquifers are the major source of water. The need to improve water productivity and increase aquifer storage and recovery (ASR) is driving the efforts for this acceleration of aquifer storage and recovery project. The objective was to model runoff in the study area using multi-source satellite data and identify regions of runoff retention and recharge. Daily runoff is simulated using a saturation excess principle with the VegET model (Senay 2008). It is a spatially explicit (500m grid cell), one-dimensional root-zone water balance model that is driven by precipitation,...

This dataset represents the average surface runoff for each HUC5 watershed, simulated by the model MC1 for the 30-year period 1971-2000. Mean surface runoff (in mm H2O yr-1), was determined for each HUC5 watershed by averaging values of original ~ 4 km raster data. Watersheds represent 5th level (HUC5, 10-digit) hydrologic unit boundaries and were acquired from the Natural Resources Conservation Service. Background: The dynamic global vegetation model MC1 (see Bachelet et al.2001) was used to simulate vegetation dynamics, associated carbon and nitrogen cycle, water budget, and wild fire impacts for OR, WA, AZ and NM, for a project funded by the USDA Forest Service (PNW09-JV-11261900-003). The MC1 model was...

The primary objectives of this research were to determine SWAT model predicted reductions in four water quality indicators (sediment yield, surface runoff, nitrate nitrogen (NO3–N) in surface runoff, and edge-of-field erosion) associated with producing switchgrass (Panicum virgatum) on cropland in the Delaware basin in northeast Kansas, and evaluate switchgrass break-even prices. The magnitude of potential switchgrass water quality payments based on using switchgrass as an alternative energy source was also estimated. SWAT model simulations showed that between 527,000 and 1.27 million metric tons (Mg) of switchgrass could be produced annually across the basin depending upon nitrogen (N) fertilizer application levels...

Over-wintering cattle out of doors can be detrimental to the areas that cattle occupy and cause increased runoff, sediment loss, and nutrient transport. Two systems of over-wintering cattle were evaluated for their environmental impacts over a 12-year period, November 1974–October 1986. In one system, beef cows were moved on 6–7 day intervals among four pastures during the summer growing season (May–October), rotated through hayed areas to eat fall regrowth, and rotated through these areas to feed on the hay made in those areas. In another system, cows were rotated weekly during summer and then fed hay in one winter area during the dormant season (November–April). Vegetative cover in the continuous wintering area...

Average annual surface runoff for the globe on a 0.5 X 0.5 degree global grid. Runoff field represents a long term annual average runoff (mm/yr) computed from monthly modeled runoff for years 1950-2000. Annual runoff - long-term annual average runoff (mm/yr) computed from monthly modeled runoff representing output from the UNH Water Systems Analysis Group Water Balance Model (Fekete et al., 2002). The data is in ESRI GRID raster format.
Evaluations of non-nitrogen nutrient budgets in pasture systems are limited, and there needs to be greater knowledge of these budgets. Although most nutrient budget studies from grasslands have focused solely or primarily on N, maintenance of a proper nutrient balance is important to healthy plant growth and reduction of potential water quality problems. Budgets of non-nitrogen nutrients were studied in a rotational pasture system during two treatment periods, which received different levels of nitrogen (N) fertility. Rotationally grazed grass pastures in Ohio (USA) received 56 kg N ha−1 as NH4NO3 for a 5-year period and then 168 kg N ha−1 for a 10-year period. A topsoil pH of 6.0 and available P and K levels of...

This dataset includes 800m resolution long-term average estimates of evapotranspiration (ET), quick-flow runoff, and recharge within a closed water budget over the 2000-2013 time period and annual estimates for the individual years. It also includes other supporting data associated with the publication of these estimation methods in a concurrent journal article. These estimates were developed with new empirical regressions for (1) quick-flow runoff data generated using data points from a USGS-developed hydrograph separation program (PART) run on streamflow data from 1434 gaged watersheds, as a function of surficial geology type (USGS), precipitation (PRISM), and soil hydraulic conductivity (STATSGO); and (2) long-term...
