Riverbeds downstream of dams are starved of sediment, impacting habitat structure and ecological function. Despite the implementation of sediment management techniques, there has been no evaluation of ...

Recent acceleration of sand extraction for anthropic use threatens the sustainability of this major resource. However, continental erosion and river transport, which produce sand and sediment in ...

Scientists have produced the first detailed estimates of how much sediment is transported onto the shores of coral reef islands, and how that might enable them to withstand the future threats posed by ...

Reservoirs around the world are losing storage capacity at an average rate of 7.3% per decade—disproportionately affecting small reservoirs, which together provide water to billions of people. The ...

Researchers have devised a better way to measure how fast sediment flows in rivers -- information that can help scientists and planners better prepare for flooding and weather-related events, ...

Sediment cores taken from the Southern Ocean dating back 23 million years are providing insight into how ancient methane escaping from the seafloor could have led to regional or global climate and ...

For the first time, researchers have measured a new class of fire retardants in Arctic Ocean sediments, far from the compounds’ intended end uses in couch cushions and television sets (Environ. Sci.

Over 200 underwater bridge tunnels exist for vehicular traffic around the world, providing connectivity between cities. Once constructed, however, these tunnels are difficult to monitor and maintain, ...

The first global digital map of the ocean floor sediments (shown above) shows we have little clue about how the world’s biggest carbon sink works. About half the carbon emitted into the atmosphere by ...

For two months, whenever I heard that cry, I would run up to the deck of the JOIDES Resolution to watch the crew pull up a 30-foot (10-meter) cylindrical tube filled with layered, multicolored rock ...

Dr Andrew Brooks has to raise his voice over the wind as it whips across a barren subdivision west of Brisbane. Brand new roads packed with empty homes end abruptly, the whole development bordered by ...
