Simulations of Sediment Movement Could Help Protect Waterways

Researchers at the Karlsruhe Institute of Technology (KIT) are using high-performance computing to model how waterways’ sediment beds change and what those changes mean for pollutants moving downstream.

While conservation efforts and environmental regulations have played an important role in limiting damage to our lakes and rivers, human pollution and natural disasters are still capable of wreaking havoc. Recognizing this risk, the Baden-Württemberg Stiftung in 2017 funded an expansive, multidisciplinary project aimed at better understanding how water quality is affected when pollution enters a river or stream.
