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-...

Autonomous Underwater Vehicle Water-Quality Surveys for Indian River Lagoon, near Titusville, Florida, August 2016-November 2017

The Indian River Lagoon (IRL) extends for 160 miles along Florida's east coast and is a complex system of three estuaries - Mosquito Lagoon, Banana River Lagoon, and Indian River Lagoon. Two concurrent phytoplankton blooms occurred in the IRL in 2011 that had detrimental ecological effects on the estuarine system. St. Johns River Water Management District (SJRWMD) is participating i

Thermal Imagery along Ellerbe Creek in Durham, North Carolina

An initial reconnaissance survey in March 2016 and a subsequent survey in July 2016 was conducted to identify possible groundwater discharge points along the stream reach using a forward-looking infrared (FLIR) camera in seasonal extremes. The high-resolution thermal imaging camera captures the emitted infrared radiation of the objects in view. Recent studies using similar ground-based therma...

Slope Area Index of Streams in North Carolina

Slope-Area Index (SAI) is used to predict erosion along a stream channel. It is a function of channel slope, and drainage area upstream raised to the exponent used in equations for flood frequency of 2-percent exceedance floods. The guidelines for use of the coefficient from 2-percent exceedance came from meetings with cooperators describing bankfull discharge as a 2-percent exceedance. The...

Hydrodynamic and Water-Quality Monitoring of Bushy Park Reservoir, 2017-2018

The Bushy Park Reservoir is a relatively shallow impoundment in a semi-tropical climate and is the principal water supply for the 400,000 people of the City of Charleston and the surrounding areas including the industries in the Bushy Park Industrial Complex. Although there is an adequate supply of freshwater in the reservoir, there are taste-and-odor water-quality concerns. The U.S. Geologic...
