A new battery made from affordable and durable materials generates energy from places where salt and fresh waters mingle. The technology could make coastal wastewater treatment plants energy-independent and carbon neutral.
To ease the pain of new state rules, engineers are looking to harness an unconventional and unwieldy source of water: the torrential storms that sometimes blast across the Pacific Ocean and soak California.
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.
Cassandra Handan-Nader and Daniel Ho have created an algorithm that reads satellite images to help environmental regulators identify potentially hazardous agricultural facilities more efficiently than traditional approaches.
In Jordan, one of the most water-poor nations, predictions of future droughts depend on the scale of climate change. Without reducing greenhouse gases the future looks dry, but researchers offer some hope.
Recent droughts caused increases in emissions of carbon dioxide and harmful air pollutants from power generation in several western states as fossil fuels came online to replace hampered hydroelectric power. A new study quantifies the impact.
