The Groundwater Toolbox: A Graphical and Mapping Interface for Analysis of Hydrologic Data

Release Date:

Overview of The Groundwater Toolbox

Flow-duration curves for measured streamflow and estimated base flow and runoff in the Groundwater Toolbox.

Flow-duration curves for measured streamflow and estimated base flow and runoff for Pawcatuck River at Wood River Junction, Rhode Island, 1971-2000, using hydrograph-separation methods provided in the Groundwater Toolbox.​​​​​​​

The Groundwater Toolbox is a graphical and mapping interface for analysis of hydrologic data. The software is a customized interface built on the non-proprietary, open-source MapWindow geographic information system software in a Microsoft Windows computing environment. The Groundwater Toolbox allows for the retrieval of hydrologic time-series data (streamflow, groundwater levels, and precipitation) from the USGS National Water Information System; preprocessed meteorological data from the National Oceanic and Atmospheric Administration National Climatic Data Center also are available with the Groundwater Toolbox.

The Groundwater Toolbox has several methods for the analysis of streamflow-hydrograph data. These methods include: 

  • six graphical hydrograph-separation techniques — the Base-Flow Index (BFI Standard and Modified), HYSEP (Fixed Interval, Sliding Interval, and Local Minimum) and PART methods; 
  • two digital filtering techniques (the SWAT Bflow and Eckhardt approaches); and 
  • the RORA recession-curve displacement method and associated RECESS program to estimate groundwater recharge from streamflow data.
