Positive Openness for North Carolina - 53 Huc 8's

Rasters of positive openness for the 53 hydrologic unit code (HUC) 8 watersheds in the state of North Carolina. Positive openness uses a line-of-sight approach to measure the surrounding eight zenith angles viewed above the landscape surface out to a specified distance. The central cells gets and average of the eight angles. An angle of 90 degrees would indicate a flat surface, while angles...

Flood-inundation areas and depths for the Withlacoochee River in Lowndes County, Georgia from Skipper Bridge Road to St. Augustine Road

Digital flood-inundation maps for a 12.6-mile reach of the Withlacoochee River from Skipper Bridge Road to St. Augustine Road, Lowndes County, Georgia, were created by the U.S. Geologicay Survey (USGS) in cooperation with the city of Valdosta and Lowndes County, Georgia. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http:%

Groundwater/Surface-Water Interactions Along Ellerbe Creek in Durham, North Carolina, 2016–18

A hydrologic study involving the investigation of groundwater-surface water interactions along Ellerbe Creek, a major tributary to upper Falls Lake, was conducted in order to determine if groundwater is a likely source of nitrate input to the stream. Groundwater-surface water interactions were characterized by synoptic streamflow measurements, groundwater-level monitoring, hydrograph-sepa

Concentrations of Pesticides, Pharmaceuticals, Organic Waste Indicators, and Volatile Organic Chemical Contaminants and Their Predicted Effects Potential in Wadeable Southeastern USA Streams

This dataset presents the results of 475 unique organic compounds collected from 54 wadeable streams within the Southeastern, USA, collected within 10 weeks during 2014. Maximum and median exposure conditions were evaluated in relation to watershed characteristics and for potential biological effects. This dataset contains the summary statistics (maximum and median concentrations)of dete

Fiber-optic distributed temperature data collected along the streambed of Ellerbe Creek, Durham, North Carolina, USA

The data set includes temperature data from the base of the water column along the sediment interface of Ellerbe Creek, Durham, North Carolina, USA, in support of a study regarding groundwater/surface water exchange. The data were collected from 07/18/2017 to 07/26/2017 using a fiber-optic distributed temperature sensing system that has 1.01 m spatial resolution along the linear

Stream Channel and Floodplain Metric Toolbox

The Stream Channel and Floodplain Metric Toolbox was developed to demonstrate the feasibility of mapping fluvial geomorphic features from high-resolution bare-earth elevation data. A Python toolbox for ArcGIS was built to calculate key metrics describing channel and floodplain geometry. Channel and Floodplain Metric Toolbox provides this ability in an automated fashion, allowing for regional...

Difficult Run field estimated floodplain and bank flux and toolbox geomorphic metrics for field sites

A cvs file containing field datasets used to develop regression models to predict sediment and nutrient retention services for streams within the Difficult Run watershed. Field measurements of floodplain deposition and bank erosion were provided in previously published datasets from Hupp et al. (2013) and Gellis et al. (2017). At each field site, 3-5 nearby cross sections from the Toolb
