AMHERST, Mass. — A new study in Science by researchers from the University of Massachusetts Amherst and University of Cincinnati has mapped 35 years of river changes on a global scale for the first time. The work has revealed that 44% of the largest, downstream rivers saw a decrease in how much water flows through them every year, while 17% of the smallest upstream rivers saw increases. These changes have implications for flooding, ecosystem disruption, hydropower development interference and insufficient freshwater supplies.
Previous attempts to quantify changes in rivers over time have only looked at specific outlet reaches or a rear basin part of a river, explains Dongmei Feng
