Possible effects of groundwater pumping on surface water in the Verde Valley, Arizona [ More info] We applied a groundwater model to simulate effects of groundwater pumping and artificial recharge on surface water in this area. Results show effects of pumping or recharge on streamflow.
Quantifying effects of climate change on the snowmelt-dominated groundwater resources of northern New England [ More info] Planned analysis of the sensitivity of groundwater levels to changes in air temperature and precipitation. Changes in groundwater recharge and discharge also will be correlated with other hydrologic indicators.
Real-time flood alert system for Puerto Rico [ More info] Web-based analytical facility designed to integrate data relevant to flood emergencies in Puerto Rico.
Relations among land cover, streamflow, and water quality in the North Canadian River Basin near Oklahoma City, Oklahoma: 1968-2009 [ More info] Data explains spatial differences and temporal trends in water quality, specifically dissolved oxygen, nitrogen and phosphorus concentrations.
Runoff conditions in Utah for water year 2011 [ More info] Describes snowpack and other factors that affected runoff in the state during this period in which the wettest 90-day period occurred.
SEAWAT: A Computer Program for Simulation of Variable-Density Groundwater Flow and Multi-Species Solute and Heat Transport [ More info] Software based on the MODFLOW modeling framework, used for studies of saltwater intrusion coastal aquifers, storage and recovery in brackish limestone aquifers, and brine migration in continental aquifers.
SPARROW Modeling of Surface-Water Quality [ More info] A software model for regional interpretation of water-quality monitoring data, estimating origin and fate of contaminants in streams, with documentation, publications and data for the applications.
Science to support the understanding of south Texas surface-water and groundwater resources in a changing landscape [ More info] Short descriptions of the research and monitoring activities we are carrying out to assist state, local, and Federal agencies dealing with water resource issues in the southern part of the state.
Sediment load from major rivers into Puget Sound and its adjacent waters [ More info] Sediment from rivers has both beneficial and detrimental effects on ecosystems and human activities around Puget Sound. We explain where the sediment comes from, how it is transported, and the nature of the data that we can use to understand it.
Slope-Area Computation Program Graphical User Interface 1.0--A Preprocessing and Postprocessing Tool for Estimating Peak Flood Discharge Using the Slope-Area Method [ More info] Explains how to use this command-line software to estimate peak flood discharge using indirect measures such as high water marks on trees or buildings.
