Science Highlights

Extensometer Hunters: Searching for Long-Lost Technologies in San Joaquin Valley

16 March 2017

San Joaquin Valley: the final frontier. These are the voyages of the U.S. Geological Survey. Its weeklong mission: to explore strange new locations, to seek out abandoned scientific technologies, to boldly go where no scientist has gone before (at least in a few decades).


National Groundwater Awareness Week: Sustainable Groundwater Management in California

06 March 2017

The National Groundwater Association has declared this week, March 5-11, as National Groundwater Awareness Week.


Winter Weather in California Keeps CAWSC Field Crews Busy

27 January 2017

It’s been a wet and snowy winter so far throughout much of California. For many Californians, that means keeping dry inside, avoiding dangerous roads, and listening closely for the rare clap of thunder. For field crews at the U.S. Geological Survey California Water Science Center (CAWSC), however, wet weather means piling on safety gear and chasing storms to make real-time high-flow and flood measurements at swollen rivers, creeks, and waterways throughout the state.


California Flood Preparedness Week

27 October 2016

This week is California Flood Preparedness week, and local, state, and federal agencies are reminding Californians to be aware and be prepared for potential potential flooding hazards as we enter the rainy season.


USGS Science Goes Overseas

30 September 2016

Bonjour from Paris! Randall (Randy) Hanson, a long-time Research Hydrologist with the California Water Science Center, delivered a keynote speech today at an international science workshop in Paris, France. Hanson discussed how water managers can apply the USGS-developed groundwater-flow model, MODFLOW-OWHM, to better understand and manage water resources. Scientists use MODFLOW to investigate and model the complex movement of groundwater and surface water both in California, and in groundwater basins across the world.
