Poor Water Management Implicated in Failure of Ancient Khmer Capital
Researchers used remote sensing technologies to map Koh Ker’s buried reservoir and calculate its capacity to hold water during the rainy season.
Europe’s Rivers Are the Most Obstructed on Earth
By analyzing satellite imagery of rivers worldwide, researchers have pinpointed over 35,000 obstructions like dams and locks that affect an environment’s ecology, hydrology, and water resources management.
Minireservoirs Could Save Farmers with Sandy Soils
A recently revived subsurface water retention technology could conserve water and drastically increase crop yields in arid landscapes with sandy soils like sub-Saharan Africa.
Hydropower and Bugs
Alpine hydropower plants commonly flush sediment that accumulates at intakes, but the associated rapid rise in discharge, turbidity, and streambed instability put aquatic insects at risk.
Will Earth’s Grandest Canyon Keep Getting Grander?
Living in Geologic Time: Rafting through the past, present, and future of the Colorado River and the Grand Canyon.
Historic Solutions to Sea Level Rise May Help Modern Communities
Earthen mounds helped ancient Dutch settlers thrive in coastal flood zones. Could historical engineering help us fight against rising seas?
Where Did All the Free-Flowing Rivers Go?
A map of the world’s free-flowing rivers shows a shrinking number can still meander as they please. New plans for hydropower will further constrain flow.
Modeling River Boulders to Improve Hydropower Sustainability
Large stones in streams provide crucial habitat for fish. Modeling the boulders and streamflow offers fresh insights into how water engineering projects alter aquatic habitats.
The Renaissance of Hydrology
Hydrology has evolved as a transdisciplinary, data-driven science in a remarkably short period of time.
