Climate, crop rotation, and stream flow data used to run the SWAT model in the Tuckahoe and Greensboro subwatersheds of the Choptank River watersheds, Maryland This posting contains the source climate and crop rotation data used to run the SWAT model in the Tuckahoe and Upper Choptank watersheds, Maryland. It also contains the monthly flow load data used for validation of model results. The data release was produced in compliance with the new 'open data' requirements as a way to make the scientific products associated with USGS research efforts and publications available to the public. It is in support of a peer reviewed journal article titled "Assessing the impacts of future climate conditions on the effectiveness of winter cover crops in reducing nitrate loads into the Chesapeake bay watershed using SWAT model." The dataset consists of the following items: 1. Greensboro...

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...

More recently, stormwater best management practices (BMPs) have been implemented in a low impact development (LID) manner to treat stormwater runoff closer to its source. This approach included the development of a novel BMP model to compare traditional and LID design, pioneering the use of comprehensively digitized storm sewer infrastructure and BMP design connectivity with spatial patterns in a geographic information system at the watershed scale. The goal was to compare total watershed pollutant removal...

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...

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.
