This site is dedicated to Coding and Statistical Data that is produced and analyzed by scientists at the MD-DE-DC WSC. We use many tools at the USGS including software exclusively developed for, sometimes written by the USGS. 

Estimation of Base Flow by Optimal Hydrograph Separation

East Coast Aquifers

OHS uses a two-parameter recursive digital filter that applies specific conductance mass-balance constraints to estimate the base flow contribution to total streamflow at stream gages where specific variables are measured.

Bank‐derived material tops fluvial sediment in suburban watershed

MD Fluvial Sediment Map

Excess fine sediment is a leading cause of ecological degradation within the Chesapeake Bay watershed. To effectively target sediment mitigation measures, it is necessary to identify and quantify the delivery of sediment sources to local waterbodies.

11 May 2020   Introduction to the dataRetrieval package

R Software
Sources/Usage: Public Domain. View Media Details

The dataRetrieval package was created to simplify the process of loading hydrologic data into the R environment. It is designed to retrieve the major data types of U.S. Geological Survey (USGS) hydrologic data that are available on the Web, as well as data from the Water Quality Portal (WQP), which currently houses water quality data from the Environmental Protection Agency (EPA), U.S. Department of Agriculture (USDA), and USGS. Direct USGS data is obtained from a service called the National Water Information System (NWIS).

Toward explaining nitrogen and phosphorus trends in Chesapeake Bay tributaries, 1992-2012

Understanding trends in stream chemistry is critical to watershed management, and often complicated by multiple contaminant sources and landscape conditions changing over varying time scales. We adapted spatially-referenced regression (SPARROW) to infer causes of recent nutrient trends in Chesapeake Bay tributaries by relating observed fluxes during 1992, 2002, and 2012 to contemporary inputs and
