Understanding spread of COVID-19
Much remains unknown about how the virus that causes COVID-19 spreads through the environment. Environmental engineers describe potential transmission pathways and their implications.
A better way to detect underground water leaks
Stanford researchers propose a new way to locate water leaks within the tangle of aging pipes found beneath many cities. The improvement could save time, money and billions of gallons of water.
Hydropower dams threaten fish habitats worldwide
New research maps the impacts of past and future hydropower development on fish habitats – and points to where restoration efforts may do the most good.
Rust offers a cheap way to filter arsenic-poisoned water
In regions that lack the resources to treat the contaminated water, it can lead to disease, cancer and even death.
More rain and less snow means increased flood risk
By analyzing more than two decades of data in the western U.S., scientists have shown that flood sizes increase exponentially as a higher fraction of precipitation falls as rain, offering insight into how flood risks may change in a warming world with less snow.
Q&A: How wildfires threaten water quality
Stanford hydrologist Newsha Ajami, an appointee to California’s regional water quality board, discusses how wildfires affect water quality, and how we can better prepare for and react to the challenges.
Q&A: Deveoping new sources for usable water
A five-year project led by a Stanford professor will research and develop cost-competitive and energy-efficient technologies to desalinate nontraditional water sources for diverse end uses from agriculture to municipal drinking water.
Making California’s water supply resilient
Stanford researchers examine effective strategies to rising water scarcity concerns in the context of climate change.
Stanford researchers find smart faucets could aid in water conservation
An experiment with a water-saving “smart” faucet shows potential for reducing water use. The catch? Unbeknownst to study participants, the faucet’s smarts came from its human controller.
Can California better use winter storms to refill its aquifers?
With new rules for groundwater management coming into effect, engineers are looking to harness an unconventional and unwieldy source of water: the torrential storms that sometimes soak California.
Domino droughts: How droughts travel across continents
New research finds one drought can amplify or trigger another. Decreased moisture recycling and transport impacts how droughts form and move across continents.
Toward safe and reliable drinking water for all Californians
Stanford scientists and water experts discuss how California can secure a safe and reliable water supply.
Can a drone reveal the murky secrets of San Francisco Bay?
Measurements of suspended sediment concentrations reveal a lot about the health of a waterway, but until now such data has been difficult to obtain.
Understanding saltwater intrusion through remote sensing
New research provides insight on a common cause of drinking water contamination in coastal areas: intrusion of ocean saltwater into freshwater aquifers.
Where will flooded fields best replenish groundwater?
Overpumping in California has depleted groundwater storage capacity and caused the land to sink. A new model could help water managers zero in on where to replenish aquifers by flooding fields.
Big livestock operations can be big polluters. But where are they?
An algorithm that reads satellite images can help environmental regulators identify potentially hazardous agricultural facilities more efficiently than traditional approaches.
The effects of climate change on water shortages
If global temperatures continue to rise, rainfall will increasingly become a beast of extremes. As a way of exploring the future risk of water shortage in a complex environment, scientists have made a case study of Jordan, one of the most water-poor nations in the world.
Know Your Planet: How do plants affect weather?
A major component of climate change unknowns stems from interactions between changes in climate and changes in ecosystems. Stanford hydrologist Alexandra Konings explains how plants shape weather patterns and influence climate.
As relicensing looms, aging dams face a reckoning
Green power source or fish killer? As older dams around the West come up for relicensing, their owners know that they’ll have to spend heavily to fix problems, while new energy sources are getting cheaper.
