flow reversal north of Vancouver and Portland? again, it doesn't say how strong it is, and I doubt it will do what you think it can do...
CALL THE CORPS OF ENGINEERS AND FIND OUT..you are not going to convince me with reports of reverse flow...a lot more is involved...
I know, that is what I am trying to solve, you want to dismiss it go ahead..
IMO, after 45+ years it is worth pursuing.. sometimes nature can do things beyond our perceptions
From my reading,,
Tidal flow pushes a wedge up the river along the bottom first with river water on top. The water level rises as incoming tidal flow progresses.
If you have a reversal on top that suggests a very strong reversal. The strongest reversal occurs at highest tides and lowest flow/discharge (1979 Columbia R).
We need to find more specific data and research on the Columbia...
Can a flow reversal push "money" at a little over 1mph from the Lewis to TBAR? That is the question
