Caltech researchers have developed a new method to measure soil moisture in the shallow subterranean region between the surface and underground aquifers. This region, called the vadose zone, is ...

During California’s historic drought from 2019 to 2022, they observed a significant decrease in vadose zone moisture, at a rate of 0.25 meters per year, surpassing the average annual precipitation.

The ability to measure vadose zone moisture in real time is crucial for managing water use and conservation efforts. Next, the team intends to deploy the technology in regions other than the desert.

Over five years, they collected data that revealed significant moisture variations in the vadose zone, particularly during California's historic drought from 2019 to 2022. Implications for Water ...

The February 2004 issue of Vadose Zone Journal contains a special section which presents over a dozen research papers about the current status of the subsurface contamination at the Idaho National ...

Additionally, moisture within the vadose zone changes rapidly, such as when a thunderstorm saturates a region that dries out a few days later. MORE FROM SENSORS. The new method from Caltech ...

On Jan. 1, 2018, the Vadose Zone Journal will switch from the subscription format to a fully open-access journal.

The Hydrologic Sciences Graduate Group provides a comprehensive hydrologic science curriculum that emphasize process-oriented critical thinking and quantitative analysis, with increasing use of ...

We report the design and installation of a distributed soil moisture sensor network in a riparian zone within the Whitewater Basin in Central Kansas. The soil-moisture monitoring network used in this ...
