Abstract: A study was conducted by the U.S. Geological Survey (USGS), in cooperation with the Gulf Coastal Plains and Ozarks Landscape Conservation Cooperative (GCPO LCC) and the Department of the Interior Southeast Climate Adaptation Science Center, to evaluate the hydrologic response of a daily time step hydrologic model to historical observations and projections of potential climate and land-cover change for the period 1952–2099. The model simulations were used to compute the potential changes in hydrologic response and streamflow statistics across the Southeastern United States, using historical observations of climate and streamflow. Thirteen downscaled general circulation models with four representative concentration...

Estimates of flows in the stream are critical to inform natural resource managers of the water availability for both human and ecological needs. Monitoring flow in the stream using a streamgage provides information about the amount and timing of surface water resources. However, not every stream has a streamgage and decisions about water resources may need to be made in a watershed where there is no flow information. Hydrologic models can be used to provide estimates of streamflow in the absence of streamflow information. These models depend upon available streamflow data for calibration, and can be very inaccurate without the use of those data. This research developed a method to group watersheds that are gaged...
Simulations of future climate suggest profiles of temperature and precipitation may differ significantly from those in the past. Future changes in climate, specifically changes in tempeature, and the type, timing, and distribution of precipitation may lead to changes in the hydrologic cycle. As such, natural resource managers are in need of tools that can provide estimates of key components of the hydrologic cycle, uncertainty associated with the estimates, and limitations associated with the climate data used to estimate these components. To help address this need, the U.S. Geological Survey (USGS) Monthly Water Balance Model Hydrology Futures Portal (https://my.usgs.gov/mows/) is a user friendly interface that...
