Estimation of Base Flow by Optimal Hydrograph Separation

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.

Bank‐derived material tops fluvial sediment in suburban watershed

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

R Software

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).
