A cvs file containing field datasets used to develop regression models to predict sediment and nutrient retention services for stream 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 Toolbox where used to represent the floodplain and streambank sampling locations at the field sites. Metrics derived from the Toolbox are provided in this data table.

This dataset describes in stream turbidity for watersheds included in a paired watershed study including a forested reference watershed and three urban watersheds with centralized or decentralized stormwater management in Clarksburg, Maryland USA. Turbidity was monitoring from June 2010 to December 2010, March 2011 to December 2011 and June 2012 to October 2012 in For-MD and Cent-MD, and only the 2011-2012 time period in Dist-MD. Mean turbidity in NTU was recorded at 5-minute intervals during the 2010-2012 monitoring seasons with a Forest Technology Systems, Digital Turbidity Sensor DTS-12. Mean turbidity was computed from 100 instantaneous recordings during the time interval. Sensor accuracy is ±2% of reading (0-399...

suspended material (water),
This dataset describes baseflow and stormflow concentration data for the constituents of nitrogen and phosphorus and suspended sediments for watersheds included in a paired watershed study including a forested reference watershed and three urban watersheds with centralized or decentralized stormwater management in Clarksburg, Maryland USA. Surface water samples were collected between the years 2004-2016. These data are interpreted in a journal article published in the Journal of Environmental Management.

This dataset describes storm event loads (sediment and total particulate phosphorus), hydrologic metrics, and precipitation characteristics for storm events occurring between 2010-2012. Loads were estimated for four watersheds included in a paired watershed study; a forested reference watershed and three urban watersheds with centralized or decentralized stormwater management in Clarksburg, Maryland USA or Fairfax County, Virginia USA. Storm event loads were estimated from surrogate relations between turbidity and the water quality parameter of interest. Hydrologic metrics were determined for each storm event using the USGS stream gage instantaneous discharge record for each watershed. Precipitation event characteristics...

dataset,
hydrographic,
Datasets used to quantify and value the ecosystem service of sediment and nutrient retention for floodplains within the Difficult Run watershed located in Fairfax County, Virginia. Geospatial datasets include a digital elevation model (DEM), a hydrologically conditioned DEM, output from the USGS Stream Channel and Floodplain Metric Toolbox, and field data sets used to develop regression models to predict sediment and nutrient retention services for stream within the Difficult Run watershed.
