cliff_processing.r Categories: Publication; Types: Citation Crystal Rock and Trib. 104 Histogram Data, 2016, Montgomery County, MD This data release includes the data used to generate histograms that compared total watershed pollutant removal efficiency (TWPRE) in the two study watersheds Crystal Rock (traditional watershed) and Tributary (Trib.) 104 low impact development (LID watershed) to determine if LID BMP design offered an improved water quality benefit. Input/calibrants data used in the model (Monte Carlo) are described in the manuscript as mentioned in the list below: -BMP Name and Type: references in the manuscript -BMP Connectivity: Proprietary (derived from Montgomery County GIS Data) -BMP Drainage Areas: Proprietary (derived from Montgomery County GIS Data) -BMP Efficiency Ranges: referenced in manuscript -Baseline Pollutant Loadings:...

Categories: Data; Tags: Maryland, Montgomery County, geographic information systems (GIS), runoff, surface water quality In situ turbidity data for urban and forested reference watersheds in Clarksburg, Maryland USA (2010-2012) 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...

The smoothed shoreline is based on the NOAA Continually Updated Shoreline Products (CUSP) found at: http://shoreline.noaa.gov/data/datasheets/cusp.html. The shoreline from Point Conception to LA Harbor was smoothed with a window of 400 m in ArcGIS 10.2.2. The smoothed shoreline was splited in 82 segments (ID range 1 to 82) and for each segment a buffer distance in meters was recorded in the attribute table (dist_buff column).

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.

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...

An ID was provided and a buffer distance expressed in meters. The ID and buff_dist columns are part of the new shapefile attribute table.

The data layer primarily uses the 2011 National Land Cover Database (NLCD) but was manually edited to include 2,219 additional reservoirs. The reservoirs were identified and digitized using 2010 National Aerial Imagery Program (NAIP) imagery.
