Credit: Unsplash/CC0 Public Domain Greater buffer zones around bodies of water and more consistent enforcement of water protection regulations are needed to reduce agriculture-based pollution in the Western U.S., a recent review from Oregon State University found. Prior research has shown that agricultural pollution, both from croplands and rangelands, is the […]
Activists fear time is running out to save what they call Europe’s last major “wild river” Cutting into craggy mountains, meandering through plains and eventually hitting Albania’s shimmering Adriatic, the Vjosa river’s untouched landscapes are a national treasure, but one that is under imminent threat. Activists feel that time is […]
The coarse gravel bed of the Emme River in Switzerland is a major control in how much and how fast river water enters the aquifer below. A new study in the watershed evaluated how water on the surface mixes and moves underground. Credit: Andrea L. Popp A new technique using […]
This March 28, 2021 image shows tumbleweeds covering a sandbar along the Rio Grande in Albuquerque, N.M. Like elsewhere in the southwestern U.S., water managers in New Mexico are warning farmers that demand is expected to outpace supply this year due to limited winter snowpack and spring runoff.

Entering a lunar lava tube. The Moon’s surface is covered by millions of craters, but it also hosts hundreds of very steep-walled holes known as pits. Like doorways to the underworld, photos of some pits clearly show a cavern beneath the Moon’s surface, suggesting that they are ‘skylights’ into extensive […]

A flood on the Rangitata River […]

That is what researchers at the Singapore University of Technology and Design (SUTD) produced after two years of research in order to better understand past […]
The arrival of the railroad and associated structures in 1850 along the banks of New York’s Hudson River Tidal Estuary in several areas created the conditions for marshes to form. Credit: the Dams and Sediment in the Hudson project In a new study of tidal marsh resilience to sea level […]
