How Transforming Riverbanks Can Clean Contaminated Waterways

9/11/2020

 
Rivers throughout the eastern United States are well known for their high banks and steep, winding courses. But in 2008 scientists proposed that years of damming rivers had transformed them from marshy streams good at filtering waste to the pollution chutes they can often be today. In 2011, they removed 22,000 tons of sediment from the banks of a small Pennsylvania stream; its success has since spurred more than a dozen similar restoration projects. Watch to learn how researchers forged a new path for shaping rivers by challenging a long-held assumption about riverbanks in the eastern United States. - Science

By redesigning the river banks the water is able to flow in a way that allows for the water to return to a more normal flow and begin the filtration process once again. This connects to our modules because it reshaping the earth and dealing with landscapes that can be affected in a geological disaster.

This article describes how removing sediments from riverbanks can help filter waste to pollution chutes. This connects to our module because with a lot of sediments in river banks, more natural disasters can form.
