Stream Lines Used to Produce the South Carolina StreamStats 2018 Release

The U.S. Geological Survey South Atlantic Water Science Center, in cooperation with the South Carolina Department of Transportation, implemented a South Carolina StreamStats application in 2018. This shapefile dataset contains vector lines representing streams, rivers, and ditches that were used in preparing the underlying data for the South Carolina StreamStats application. Data were...

Distribution of Phosphorus in Soils and Aggregated within Geologic Mapping Units, Conterminous United States

This data release comprises four datasets that represent Phosphorus concentration in the A and C horizon of soils within the conterminous United States. The source dataset is a slight modification of the data published in the report "Geochemical and mineralogical data for soils of the conterminous United States", http://pubs.usgs.gov/ds/801/. Data...

Streamflow and precipitation event statistics for treatment, urban control, and forested control watersheds in Clarksburg, MD USA (2004-2018)

This dataset describes streamflow and precipitation event statistics for four watersheds located in Clarksburg, Maryland, USA. Streamflow and precipitation events were identified from fourteen years of sub-daily (5- and 15-minute) monitoring data spanning October 1, 2004 through September 30, 2018. A 6-hour inter-event window was used to define discrete streamflow and precipitation events. The...

Digital Surfaces of the bottom altitude and thickness of the Mississippi River Valley alluvial aquifer and site data within the Mississippi Alluvial Plain project region

Bottom altitudes of the Mississippi River Valley alluvial aquifer (MRVA) were compiled from interpretations of subsurface geophysical logs (log picks) at about 10,000 boreholes and wells located throughout the Mississippi Alluvial Plain (MAP) that were available from previous investigations. Five sources of the bottom altitude data are listed numerically in the Cross Reference section (below)...

Stream habitat and geomorphic characteristics above and below culverts at selected sites in South Carolina (2017)

This dataset contains six individual tabular data files. These tabular data files contain measurements of aquatic habitat features and stream channel geomorphology from 20 sites in the Piedmont and Upper Coastal Plain physiographic regions of South Carolina. Specifically, the dataset titled "bedform_slope" contains enumeration of occurrence of bedforms, or macro-habitat features, and streambed...

Water-quality data for surface-water samples collected from October 2015 through September 2017 at the Triangle Area Water Supply Monitoring Project study sites, North Carolina

The dataset contains the environmental data collected for the Triangle Area Water Supply Monitoring Project. The data are from the samples collected during routine and storm-runoff sampling events during October 2015 through September 2017. Several study sites contained in this dataset were sampled for other USGS projects during the same time frame. Unless the samples at these sites were...

Analytical results for blanks collected during surface-water sampling at the Triangle Area Supply Monitoring Project study sites, North Carolina, October 2015 through September 2017

The dataset contains the analytical results for quality-control samples collected during the surface-water sampling for the Triangle Area Water Supply Monitoring Project. The data are equipment blanks, sampling-vehicle (ambient) blanks, and field blanks collected during October 2015 through September 2017. Several study sites contained in this dataset were sampled for other USGS projects...

Precipitation Runoff Modeling System Output Data from Hydrologic Simulations of the Southeastern United States for Historical and Future Conditions

The southeastern United States was modeled to produce historical and potential future simulations of streamflow statistics using the Precipitation Runoff Modeling System (PRMS) as part of the study documented in LaFontaine and others (2019). Hydrologic simulations using one observation-based historical climate dataset (Maurer and others, 2002), 13 used historical climate simulations using...

Analytical results for the environmental and replicate sample sets collected from October 2015 through September 2017 at the Triangle Area Water Supply Monitoring Project study sites, North Carolina

The dataset contains the analytical results for environmental and quality-control replicate sample sets and the computed relative percent differences (RPD) greater than 25 percent for the data collected during the surface-water sampling for the Triangle Area Water Supply Monitoring Project. The data are from samples collected during October 2015 through September 2017. Several study sites...

Model Input and Output for Hydrologic Simulations of the Southeastern United States for Historical and Future Conditions

This data release contains inputs for and outputs from hydrologic simulations of the southeastern U.S. using the Monthly Water Balance Model, the Precipitation Runoff Modeling System (PRMS), and statistically-based methods. These simulations were developed to provide estimates of water availability and statistics of streamflow for historical and potential future conditions for an area of...

Geomorphological Features of North Carolina

For these three statewide datasets of North Carolina, information was extracted and post processed from lidar derived digital elevation models (DEMs) at 10 ft. and 30ft. resolution. Datasets are currently used for the project SPARROW Modeling for North Carolina Watersheds, but have the potential to be used in numerous applications. Slope area index (SAI), the ten most common geomorphons (i.e....
