Researchers discover that rock distribution on riverbeds has more to do with the river’s shape than water flow

If you want to know what your local river will look like in the future, your best clue is to inspect its rocks. A joint Scottish-French study on waterfalls suggests that the type of rock on a riverbed have a much bigger impact on the evolution of rivers and waterfalls than the amount of water coursing […]

Useful way to repurpose invasive weeds: Water hyacinth, an invasive plant to river ecosystems, may prove useful for oil sorption

Those thick clumps of water hyacinth clogging our waterways might be useful for something, after all. A Thai study suggested that the invasive floating plant can be turned into biodegradable adsorption materials that can clean up oil spills better than polypropylene-based sorbents. The findings were published in the International Organization of Scientific Research. Polypropylene is a […]

Dangerous, toxic, potentially catastrophic: Tailing ponds for copper mine quietly being planned upstream from the St. Louis River, Lake Superior

A Global Research article drew attention to the quiet plans of a foreign corporation to set up insufficiently secure toxic tailing ponds for its copper mine sited upstream of the vital St. Louis River in Minnesota. According to the article, PolyMet Mining is planning to set up an “enormously dangerous [and] potentially catastrophic” lagoon that will store […]

Wetlands reduce nitrate pollution in rivers and streams five times more efficiently than land-based mitigation strategies

Nitrate pollution comes from the nitrate used in crop fertilizers that goes to rivers and streams through drainage systems and agricultural ditches. High concentrations of nitrate in rivers and streams can be toxic to ecosystems and human health, as they may contaminate drinking water. As a result, a team of researchers from the University of […]

Preserving riverside forests by connecting fragmented habitats may conserve biodiversity, ecosystems

Aside from protecting various endangered species, the conservation of river-floodplain ecosystems is another challenge that experts are trying to address in the 21st century. According to a group of researchers from the University of Tsukuba in Japan, landscape genetics can be used to help sustain threatened ecosystems. The high soil moisture in forests on the […]
