The U.S. geological survey hydrologic analysis support section software support services for hdyrologic modeling and data analysis

摘要

The U.S. Geological Survey (USGS) provides computer programs for surface-water, ground-water, and water-quality investigations. The programs include flow models, solute transport models, geochemcial computation models, hydrologic computations, charting programs, data management, and utility programs. The purpose of this document is to provide instructions on how to obtain the software and documentation and to provide a brief description of the programs currently available.
