Estimation of Base Flow by Optimal Hydrograph Separation
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.
Wastewater Nutrient Data Preps, Estimates using PSLoadEsT
The Point-Source Load Estimation Tool (PSLoadEsT) provides a user-friendly interface for generating reproducible load calculations for point source dischargers while managing common data challenges. This report serves as a detailed user's guide.
Bank‐derived material tops fluvial sediment in suburban watershed
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
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).

This research theme addresses several issues important in deriving accurate and precise estimates of fatality at wind and solar power-generation facilities.Everything you need to know about SPARROW
What is SPARROW? SPARROW (SPAtially Referenced Regression On Watershed attributes) is a watershed modeling technique for relating water-quality measurements made at a network of monitoring stations to attributes of the watersheds such as contaminant sources and environmental factors that affect rates of delivery to streams and in-stream processing. The core of the model consists of a nonlinear...Delaware River Basin Focus Area Study: Statistical Streamflow Modeling
The Delaware River Basin Streamflow Estimator Tool (DRB-SET) uses historical records of streamflow to estimate daily mean streamflow at any stream location within the Delaware River Basin for the period 1960-2010, incorporating basin characteristics such as drainage size, soil, geology, and seasonal precipitation.Determining Nutrient and Sediment Loads and Trends in the Chesapeake Bay Watershed by Using An Enhanced Statistical Technique
As the largest and most productive estuary in North America, Chesapeake Bay is a vital ecological and economic resource. In recent decades, however, the bay and its tributaries have been degraded by excessive inputs of nutrients (nitrogen and phosphorus) and sediment from contributing watersheds, and in 1998, the Chesapeake Bay and its tidal tributaries were listed as “impaired” under the Clean...USGS-Chesapeake Bay Program Watershed Model
The USGS is collaborating with the Chesapeake Bay Program (CBP) to incorporate the USGS Potomac Watershed and Chesapeake Bay Virginia Watershed models into Phase 5 of the Chesapeake Bay Watershed Model (CBWM). - Publications
