large tanker truck is 9000 gal. which is 1203 cubic ft.

so...
200 KCFS = 167 tanker trucks per second Shocked
how much mass is that?
how much energy?

Amazing thing is the system that puts all that water (energy) there in the first place. What is it?

amazing!

can't help with the physical education questions but did run a river in a duckie (pre self-bailng) with a friend in PA

normal flow 200 CFS we got a special day - 24 KCFS

water was hitting the bridge abutments on I-80 and shooting 20 feet in the air

the river is a bit smaller than the Columbia...

I'm still waiting for the Corps to tap into the outlet water pipe. I think Hein, correct me here, said that the water is warm.

That would be cool.

The kiter lost her board and attempted to go after it. Body dragging in the strong current took her upwind faster than any of us could follow and into the path of a barge.
She managed to get to the board and attempted to start riding but the safety blew by accident, crashing the kite and tangling the lines. I'm not sure if the barge actually turned or if she was just outside if it's path but it was really, really close.

Physics aside, while it may be possible for the kite to float toward the kiter, in this case the kiter pulled the kite in without wrapping her lines (once the barge had narrowly passed). I tried to get into position to tow her, her board, and my surfboard to the side of the river but was having trouble getting a hold of her board. I was trying to put her board on my feet and get her to hold the surfboard on top of her kite, but got seperated from her. Once I realized that we were both in danger of getting tangled I told her that she should ditch the kite and that I'd pull her in from there. After she let go of the kite one of the lines got caught on the back of her harness and started dragging her under. With the kite pulling one way and the current going strongly the opposite way, she started going under and came pretty close to drowning. I told her to take her harness off but she couldn't and she went under a few more times before I could get an arm on her. It turns out that the harness is difficult to get off at the best of times. She managed to release the kite line and I blew the safety on her leash and we dragged to shore from there.

Thanks Matt for coming all the way up there, we were way upwind. The kite was later recovered from the far side of the river (cheers to the portland guys with the RV and jetskis, thanks for your help).

That was easily my scariest day on the water. Upwind currents can be a lot of fun but like Matt said, they make bad things worse (and in this case a whole lot worse).

Big ups to you for helping her out and risking both yourself and your gear. It's awesome we have so many good people around looking out for us.

Currents riptides and objects under the water such as a sandbar are very dangerous and something to consider when shit goes wrong (if you kite enough it all goes wrong)

On the harness issue ,I recently purchased the Ocean rodeo Sessions -2
harness and while it fits well and snugs up tight.I really like the thing
mostly because it does not compress my diaphram and is very comfortable
There would be no way to discharge it ,as such with all harnesses I've seen

Except for my friend who has used a automotive seat belt release. It's at least 10 years old and still works like a champ
I am going to put some effort into a quick release for my harness

After reading about the kitesurfer tangled in his lines in S.F.and drowning

Throw in the barge Shocked
Getting drug by waves is something that can happen every couple seconds.
remember hands over head waving is the universal signal for help

Nice job Kerf. That was WAY scary Shocked Shocked

Glad to hear you guys got the kite back. I saw it sitting exactly where it was on the against that small cliff on the WA side of the river when driving home that afternoon.

Once again glad everybody is okay hopefully you guys make it back to the gorge for a less-epic adventure next time!

hourly current data:

Normal summer flow is around 100 KCFS
200+ KCFS is a shit ton of fast moving water.
over 300 is a raging torrent not even worth riding in.
(unless you are a death wish weekend warrior)

It's good to think about magnitudes.
so how big is a 1000 cubic feet of water?


Today it's 400,000 CFS. The river is raging down there. Along with the gusty wind, great fun for you thrill seekers.

DAMN!! That is 2,992,000 gallons of water...per minute!!

You could make 1600 pairs of blue jeans per minute with that much water

I guess Rufus is not an option this weekend with current topping 500 KCFS?
Anyone been out there lately?

Sounds like Kerf topped off his karma for the season!
That Rufus current is damn wacky - can't imagine what it'd be like at 500,000+ CFS.
Glad everything worked out.

I mentioned the flow to my Dad and he had this to say:

Quote:
A half million cfs is a lot of water indeed! For people who are
willing to think that becomes quite embarrassing; -to see how much
more water is in the atmosphere than carbon, and how much faster
it travels into the air and back out.

When the current is stronger, the water moves faster.

Hein, dump your wacky right wing shit somewhere else. It doesn't have anything to do with this thread.

Agreed

NWkite is no place for logic, facts and science. You are hurting my feelings.

PostMon May 30, 11 5:41 am    KSR has wave runner suport service for $45 Reply with quote

This woman should have booked in at KITE SCHOOL RUFUS for our Novice Kiter wave runner support program. Then I would have been right there to relaunch the kite for her. All of you should do this before attempting to ride such extreme conditions. Have fun with it. So it cost $45. Much cheaper than lost gear or hospital bill! I'll be happy to help all who need it!
