The Columbia River basin will see an increase in flooding over the next 50 years as a result of climate change, new modeling from Oregon State University indicates.
The magnitude of flooding – the term used to describe flooding severity - is expected to increase throughout the basin, which includes the Columbia, Willamette and Snake rivers and hundreds of tributaries. In some areas, the flooding season will expand, as well.
“The flood you’re used to seeing out your window once every 10 years will likely be larger than it has been in the past,” said the study’s lead author, Laura Queen, a research assistant at OSU’s Oregon Climate Change Research Institute.
The findings are based on natural river conditions and do not take into account potential flood control measures, including dams, but the increases are significant nonetheless, said study co-author Philip Mote, a professor in the College of Earth, Ocean, and Atmospheric Sciences and dean of the Graduate School at OSU.
