Estuaries, where rivers pour freshwater into the ocean, could become giant power plants with the help of a newly made membrane. LWM/NASA/LANDSAT/ALAMY STOCK PHOTO BOSTON—Green energy advocates may soon be turning blue. A new membrane could unlock the potential of “blue energy,” which uses chemical differences between fresh- and saltwater […]

Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation (PDE) model to find the desired flow rate to reduce invasive populations. The model is detailed in a new paper […]

Satellite images used in the study show deforestation and elevated suspended sediment (orange/brown water) due to gold mining operations in the Rio Inambari and Rio Colorado watersheds in Peru.
