Model Development
The USGS is at the forefront of devising new techniques and computer software to solve practical problems in the study of water resources.
Predictive models are needed to make informed decisions in many emerging areas related to the effects of water resources development. New models and methods enhance all USGS water programs. State and local governments as well as scientists and engineers in the private sector regularly use USGS models as an integral part of their work.
Numerical simulation software is critical to the water resource studies of the USGS Water Availability and Use Science Program (WAUSP). Software developed and maintained by the USGS are integral to WAUSP studies and are required to effectively forecast future conditions. Moreover, this software is used in studies across the USGS.
WAUSP supports modeling software development to:
- simulate groundwater and surface-water flow;
- allow the creation and viewing of groundwater and surface-water models with graphical user interfaces;
- automate the fine-tuning (calibration) of models to real-world data;
- separate the primary components of streamflow into runoff from the land surface and groundwater discharge from adjoining aquifers with the Groundwater Toolbox;
- store and retrieve subsurface information with the GeoLog Locator web service;
- estimate groundwater recharge;
- analyze temperature, flowmeter, and geophysical data.

MODFLOW and Related Programs
MODFLOW is the USGS's modular hydrologic model. MODFLOW is considered an international standard for simulating and predicting groundwater conditions and groundwater/surface-water interactions. MODFLOW 6 is presently the core MODFLOW version distributed by the USGS. The previous core version, MODFLOW-2005, is actively maintained and supported as well.Integrated Water Prediction (IWP)
The USGS Integrated Water Prediction science program focuses on the development of advanced models for forecasting multiple water quality and quantity attributes including water budgets and components of the water cycle; water use; temperature; dissolved and suspended water constituents, and ecological conditions. It is also developing the cyberinfrastructure and workflows required to implement...National Hydrologic Model Infrastructure
The USGS National Hydrologic Model (NHM) infrastructure supports the efficient construction of local-, regional-, and national-scale hydrologic models. The NHM infrastructure consists of: 1) an underlying geospatial fabric of modeling units with an associated parameter database, 2) a model input data archive, and 3) a repository of the physical model simulation code bases. - Publications
