Researchers found that most US watersheds are too small and lack sufficient sediment to sustain tidal wetlands as sea levels rise. Scientists now recommend allowing wetlands to migrate upslope or restoring natural hydrology to preserve low-lying land, alongside other engineering approaches.
A study found that crayfish increase macroinvertebrate density in polluted streams. The presence of crayfish also reduces sediment settling, creating a more favorable habitat for these organisms. This research highlights the potential benefits of invasive species like crayfish in alleviating problems in impaired streams.
A $475,000 grant will support a study examining the huge amount of particulate organic nitrogen transported downstream during intense storms and its impact on freshwater streams and rivers. The researchers aim to understand how this contributes to the overall nitrogen load and what happens to the particulate materials.
A $3 million grant will restore 14.4 miles of streams in Pennsylvania, reducing flooding and improving water quality. The project will also create a riparian forest buffer to support a breeding population of native brook trout and other coldwater fish species.
The expanded module will help high school students learn how land use impacts freshwater quality in their own geographic regions. The website, funded by a $2.9 million dollar grant, provides students with hands-on learning experience using real data and geospatial analysis tools.
Melinda Daniels joins Stroud Water Research Center to lead climate-based water-sustainability research project and advise the US Army Corps of Engineers on environmental impacts. She will investigate water sustainability in the Smoky Hill basin and develop a policy optimization strategy.
Scientists at Stroud Water Research Center are investigating how a stream's ecosystem changes as trees along the banks mature. The five-year NSF grant will provide funding for new data collection using cutting-edge technologies to study physical, chemical, and biological attributes of the stream.
Current international strategies overlook the role of inland waters in carbon cycling, but a new study highlights their disproportionate impact. The study suggests that rivers and lakes can alter the fate of terrestrial carbon, leading to significant changes in global carbon budgets.
