Assessment of nutrient load estimation approaches for small urban streams in Durham, North Carolina
This cooperative study between the City of Durham Public Works Department, Stormwater Division and U.S. Geological Survey evaluated whether alternate monitoring strategies that incorporated samples collected across an increased range of streamflows would improve nutrient load estimates for Ellerbe and Sandy Creeks, two small, highly urbanized streams in the City of Durham, North Carolina. Water-qu
Detection of periodic peaks in Karenia brevis concentration consistent with the time-delay logistic equation
The logistic equation models single-species population growth with a sigmoid curve that begins as exponential and ends with an asymptotic approach to a final population determined by natural system carrying capacity. But the population of a natural system often does not stabilize as it approaches carrying capacity. Instead, it exhibits periodic change, sometimes with very large amplitudes. The tim
Interdisciplinary science approach for harmful algal blooms (HABs) and algal toxins—A strategic science vision for the U.S. Geological Survey
Executive SummaryAlgal blooms in water, soils, dusts, and the environment have captured national attention because of concerns associated with exposure to algal toxins for humans and animals. Algal blooms naturally occur in all surface-water types and are important primary producers for aquatic ecosystems. However, excessive algae growth can be associated with many harmful effects ranging from aes

Manning's Roughness Coefficients for South Carolina Streams
The objective of this project will be to verify channel and flood plain Manning’s roughness coefficients (n) for selected streams in South Carolina. For streams with cross sections that warrant subdivision of the n values, the verification for the channel and flood plain will be performed by subdividing the n values instead of using a composite n value. The n values will be determined for various...
Raleigh Bank Erosion Project
The City of Raleigh partnered with the U.S. Geological Survey (USGS) to assist in assessing streambank erosion hotspots along the City of Raleigh’s stream network to support the City’s efforts of prioritizing future stream mitigation projects. Streambank erosion potential will be assessed using remotely sensed light detection and ranging (lidar) data, field assessments of streambank conditions...
