Measurements of suspended sediment concentrations reveal a lot about the health of a waterway, but information has been difficult to obtain. A new approach uses a drone to take high-resolution photos to reveal turbidity.
Overpumping in California’s Central Valley has depleted groundwater storage capacity and caused the land to sink. A new model could help zero in on where water managers can replenish aquifers by flooding fields.
Scientists are training machine learning algorithms to help shed light on earthquake hazards, volcanic eruptions, groundwater flow and longstanding mysteries about what goes on beneath the Earth’s surface.
Geophysical processes have shaped Pozzuoli, Italy, like few other places in the world. Stanford students applied modern tools to understand those links and what it means to live with natural hazards as both threat and inspiration.
Why did the first big, complex organisms spring to life in deep, dark oceans where food was scarce? A new study finds great depths provided a stable, life-sustaining refuge from wild temperature swings in the shallows.
Stanford researchers have mapped local susceptibility to human-made earthquakes in Oklahoma and Kansas. The new model incorporates physical properties of the Earth’s subsurface and forecasts a decline in potentially damaging shaking through 2020.
