Surface-Water Routing (SWR) Process: A Program for Modeling Surface-Water Flow with the USGS Modular Groundwater Flow Model (MODFLOW)

The Surface-Water Routing (SWR) Process is used to accurately simulate stages, surface-water flows, and surface-water/groundwater interactions in areas where surface-water gradients are small and/or there is significant management of surface water.

Central Valley Hydrologic Model (CVHM)

The Central Valley Hydrologic Model (CVHM) is an extensive, detailed three-dimensional (3D) computer model of the hydrologic system of the Central Valley (Faunt, 2009). The Central Valley Hydrologic Model (CVHM) simultaneously accounts for changing water supply and demand across the landscape, and simulates surface water and groundwater flow across the entire Central Valley.

SmartRiver GIS

Smart River GIS allows simultaneous views of river hydraulics, species-specific habitat, and fish population simulations, for a better understanding of complex ecological interactions. We used existing data sets from the South Platte River in Colorado to develop a multi-layered geographic information system (GIS) that resource managers can use to improve their understanding of river...

The Connecticut River UnImpacted Streamflow Estimation (CRUISE) Tool


The Connecticut River UnImpacted Streamflow Estimation (CRUISE) tool combines the utility of catchment delineation at any location along a stream with the estimation and serving of daily streamflow information. The CRUISE tool is freely-available and requires only an internet connection and Microsoft Excel version 2000 or higher.

The Massachusetts Firm-Yield Estimator, version 2.0


The firm yield of a reservoir is defined as the maximum yield that can be delivered from a system without failure, even during a severe drought. The Firm Yield Estimator model (FYE) uses the daily water-balance equation to estimate reservoir storage from October 1, 1960 to September 30, 2004, which includes the most extreme drought of record.

The Massachusetts Sustainable-Yield Estimator (MA SYE)


The Massachusetts Sustainable-Yield Estimator is a decision-support tool that provides screening-level estimates of the sustainable yield of a basin, defined as the difference between the unregulated streamflow and a user-specified quantity of water that must remain in the stream to support such functions as recreational activities or aquatic habitat.

Conduit Flow Process (CFP): A Program to Simulate Turbulent or Laminar Groundwater Flow Conditions

Conduit Flow Process (CFP) allows simulation of laminar and turbulent flow within a standard MODFLOW layer and/or simulation of a hybrid model (one-dimensional pipe network coupled to MODFLOW).

HRDB: Highway Runoff DataBase - Software page


The highway-runoff database (HRDB) was developed to serve as a data warehouse for current and future highway-runoff data sets. The database can be used by transportation agencies and researchers as a data warehouse to document information about a data set, monitoring site(s), highway-runoff data (including precipitation, runoff, and event mean concentrations...

One-Dimensional Transport with Equilibrium Chemistry (OTEQ): A Reactive Transport Model for Streams and Rivers

OTEQ is a mathematical simulation model used to characterize the fate and transport of waterborne solutes in streams and rivers. The model is formed by coupling a solute transport model with a chemical equilibrium submodel. The solute transport model is based on OTIS, a model that considers the physical processes of advection...
