Detailed Description

A hydrologic model is a simplified conceptual and computer model used to simulate and predict the movement and use of water. It takes into account various or all components of the landscape, aquifer system, and water cycle and provides a framework to organize data, knowledge, and understanding of hydrologic systems. Models can provide insights that water-resource managers need to plan effectively for future water demands and to answer scientific and management questions.

The USGS models shown on this site are in the public domain, and are freely available. They are based on MODFLOW and other public-domain USGS software. Links to publications and web resources associated with each model are shown in the table next to the model map. The associated model files for some of these models are currently available for download via this page
