Oregon State University’s Gordon Grant makes some salient points in this recent Hydrological Processes paper.
I completely agree with his statement on the lack of rigorous pre and post dam removal analyses, although my co-worker Matt Collins at NOAA is doing his best to take a crack at it. I also like Dr. Grant’s point on dam removal being an experiment with a known perturbation.
Well planned pre & post monitoring studies need money, which all too often, is lacking in dam removal projects.
If you are not familiar with Dr. Grant’s work, here’s a nice video of him working in at U. Minnesota’s St. Anthony Falls Lab provided by National Geographic. Do you think he enjoys his work?
