• AMDTreat - Acid mine drainage pollution abatement cost estimating software.
  
  
• AQTESOLV - A suite of tools to analyze movement and quantity of ground water, estimate aquifer parameters and to evaluate pump/slug well test results.
  
  
• AqQA – Simple to use software that can be used to plot water quality graphs, evaluate water types, and perform simple water quality calculations.
  
  
• The Geochemist’s Workbench - A collection of sophisticated modules for solving aqueous geochemistry problems.
  
  
• Groundwater Modeling System - Ground-water model design system that converts map data into MODFLOW, MODPAT, and MT3D grid data.
  
  
• Groundwater Vistas - Groundwater Vistas is a model-independent graphical design system for MODFLOW, MODPAT, and MT3D.
  
  
• HEC-RAS - A frequent use of the HEC-RAS model is the investigation of the impacts of encroachment upon the floodplain (flood analysis); for example delineating the approximate limits of the 100-year floodplain.  In addition, the effects of various obstructions such as bridges, culverts, weirs, and other structures in the flood plain can be considered in the computations.

• BETCO: Barometric and Earth Tide COrrection (Sandia National Lab) - BETCO is a Windows-executable program that removes noise from water levels caused by barometric pressure and Earth tide effects.
  
  
• FSWEPP (USDA Forest Service)
  
  
• GSFLOW (USGS) - Coupled Ground water and Surface-water FLOW model based on the USGS Precipitation-Runoff Modeling System (PRMS) and Modular Ground Water Flow Model (MODFLOW-2005).
  
  
• HYSEP (USGS) - HYSEP performs hydrograph separation, estimating the ground-water, or base flow, component of streamflow.  The program provides an automated and consistent method for estimating base flow.  Any of the three hydrograph-separation techniques of Pettyjohn and Henning (1979) can be used:  fixed interval, sliding interval, or local minimum.
  
  
• National Streamflow Statistics (USGS) - To provide simple methods of estimating streamflow statistics, the U.S. Geological Survey (USGS) has developed and published regression equations estimating the magnitude and frequency of floods for every State, the Commonwealth of Puerto Rico, and a number of metropolitan areas in the United States, and regression equations for estimating other streamflow statistics are available for many states. These equations have been compiled into the National Streamflow Statistics (NSS) Program.
  
  
• RORA (USGS) - The computer program RORA estimates ground-water recharge using the recession-curve-displacement method. The method is based on the change in total potential ground-water discharge that is caused by each recharge event.
  
  
• StreamStats (USGS) - StreamStats is a Web-based tool that allows users to obtain streamflow statistics, drainage-basin characteristics, and other information for user-selected sites on streams.
  
  
• Visual MINTEQ (USGS) - a freeware chemical equilibrium model for the calculation of metal speciation, solubility equilibria, sorption etc. for natural waters. It combines state-of-the-art descriptions of sorption and complexation reactions with easy-to-use menus and options for importing and exporting data from/to Excel.
  
  
• WEPP (National Soil Erosion Research Laboratory) - The Water Erosion Prediction Project (WEPP) model is a process-based, distributed parameter, continuous simulation, erosion prediction model for use on personal computers running Windows 95/98/NT/2000/XP.
  
  
• WinXSPRO (USDA) - WinXSPRO is a software package designed to analyze stream channel cross section data for geometric, hydraulic, and sediment transport parameters. WinXSPRO was specifically developed for use in high-gradient streams (gradient > 0.01) and supports four alternative resistance equations for computing boundary roughness and resistance to flow. Cross section input data may be from standard cross section surveys using a rod and level or sag-tape procedures
