The USGS is home to many kinds of scientists studying the earth’s hydrology, topography, geography, geology, seismology, volcanology, and more. 

In this video, we show you what a day is like for scientists studying a stream’s habitability.

Groundwater that drains to surface water through seeps and springs is generally referred to as “discharge.” Groundwater discharge is a primary component of stream base flow, or streamflow that occurs between storms, periods of snowmelt runoff, and periods of quick soil drainage.
