Welcome to the Hydrogeophysics Branch internal web site
Learn about what we doHydrogeophysics Branch
The Earth System Processes Division Hydrogeophysics Branch (HGB) supports the USGS Water Resources Mission Area in the development and application of hydrogeophysical techniques that enhance groundwater resource assessment, modeling, and monitoring by:
- providing technical assistance to the USGS Water Science Centers;
- conducting applied research ; and
- training USGS offices on the use of geophysical methods and equipment.
Training & Support
Get technical assistance through formal courses, online video on demand, and informal HGB support.
Tools & Methods
Learn more about hydrogeophysical methods, or borrow tools through the ESPD geophysical equipment program.
Products
Find and download HGB publications, decision support tools, software, and data.
