When Rivers and Tides Collide
Scientists review several decades of research on the complex freshwater reach where fluvial and tidal forces meet.
Controversial Pacts Aim for Dam Removals on Western U.S. River
New agreements regarding the Klamath River in Oregon and California would enable the largest U.S. dam removal project ever. Critics say water quality will suffer, decry hydropower loss.
Tidal River Dynamics
Tidal rivers are a vital and little studied nexus between physical oceanography and hydrology.
Bark Beetles Cause Big Tree Die-Offs, but Streams Flow Steadily
Recent beetle epidemics have driven tree die-offs across North America, and previous studies predicted an increase in annual streamflow would follow—but a new study shows this may not be the case.
Predicting Changing Human Preferences in Water Basin Management
A model of human-water interactions in Florida's Kissimmee River Basin demonstrates the potential for sociohydrologic models to assist with strategic water management decisions.
California Is the Driest It's Been in 2000 Years
Scientists reconstruct the paleohydrology of Tulare Lake to unravel the region's long-term drought history.
Modeling the Future of Dissolved Organic Carbon in Boreal Forests
Climate change and forest harvesting will increase the concentration and flow of dissolved organic carbon in boreal streams.
Night Lights Illuminate Human Presence near Rivers
Nocturnal satellite imagery and other fine-scale data could improve global water resources management.
Contaminated Sediment and Dam Removals: Problem or Opportunity?
Restoring rivers to their free-flowing state promises a host of environmental benefits, but contaminated sediments may cloud the picture.
