[Geolalumni] New Compound Flood Model for the Nooksack River and assessment of sediment effects and nature-based strategies

[Eric Grossman]

Hi All,
as many of you are scientifically interested and/or vested in our wonderful Nooksack watershed, I want to share with you a new publication. It summarizes research and modeling we have conducted to assess the changing vulnerability to flood exposure of the lower Nooksack River to (1) the combined influence of higher sea level and stream runoff into the 2040s and 2080s, (2) observed decadal scale sediment dynamics and channel bed aggradation patterns, (3) cumulative effects of nature-based strategies to mitigate the anticipated increases in flood exposure, and (4) expected sediment responses to the restoration alternatives.

This is another example of exciting research we have been able to pursue through our USGS-WWU collaboration!

Higher sea level and stream runoff associated with climate change is expected to lead to greater lowland flooding across the Pacific Northwest. Increases in stream runoff that range from 20 to 32 percent by the 2040s and from 52 to 72 percent by the 2080s is expected to steadily increase flood risk. Flood risk is also expected to increase in response to the landward shift in high tides and storm s
