China's Three Gorges Dam, a massive hydroelectric power generator, is being constructed on the Yangtze River. NASA satellites have provided detailed views of the dam's construction and its impact on climate and environment.
A recent study highlights the urgent need to update design standards in stable continental regions like Peninsular India. The assessment shows that major urban areas are underprepared for earthquakes, with risks exceeding current safety standards.

Creality K1 Max 3D Printer rapidly prototypes brackets, adapters, and fixtures for instruments and classroom demonstrations at large build volume.
Researchers use a massive centrifuge to simulate earthen dam failures and study the effects of sinkholes on full-sized dams. The 400g-ton machine, built in 1988, can spin loads of up to 2 tons at 200 times gravity.
Researchers developed a multibeam sonar tool and interactive software to study fish behavior near dams. The tools allow for detailed analysis of fish movement, enabling scientists to understand why fish exert more effort to pass through bypasses.

Inflatable dams offer a range of benefits, including flexible flood protection solutions and minimal maintenance requirements. They can be used to control water levels, prevent backflows, and even provide recreational spaces while maintaining flood protection.
A new USGS report explores the environmental consequences of dams, including erosion, waterfowl habitat changes, and loss of river sand bars. The report emphasizes the importance of interdisciplinary scientific approaches to minimize negative impacts and promote informed decisions about dam management.
