As densely populated coastal communities struggle to keep up with rising sea levels, new research reveals a way to predict how river deltas build land and protect coastal regions from encroaching oceans. This insight will help engineers and policymakers estimate how much new land can be created or maintained when human intervention is used to redirect river channels, making these efforts more effective for coastal restoration and flood protection.
A widely used method for measuring how well streams absorb excess nutrients has a hidden flaw: it systematically overestimates uptake length under high-nutrient conditions. Researchers at Duke Kunshan University have derived a corrected zero-order analytical approach that better captures stream nutrient processing when nutrients are abundant, improving the accuracy of tools used to assess river health and guide restoration decisions.
Why this matters:
Hydropower is a major source of clean energy, including via dams, but building dams can come at a cost by disrupting communities, wildlife and river ecosystems.
MSU researchers worked with an international research team and found that better planning, especially involving local communities and using a mix of energy sources like solar and wind, can reduce dam construction harms.
The findings highlight a key challenge in the clean energy transition: how to expand renewable power without damaging the people and environments it is meant to protect. The researchers are working to advance global conversations on how to address the challenges surrounding dam projects.
