RE: [asa] Re: Slug

I thank you for that piece of information. I am not entirely sure why a
fast velocity entirely wrecks my views. All one needs is that at the end of
the dam breakage, after all the erosion is finished, that the lip at the
Atlantic end of the Mediterranean be 1000 m deep or so close to it that
larvae can be sucked in to the Med to explain the ostracods.
 
No one knows the width or length of the channel leading into the Med. The
only constraint we have is on the depth. A narrower channel would fill
slower, a wider one faster. So, your approach here to try to kill my views
with a too rapid infill are really hitting a place where there is lots of
flexibility.

I'm not even looking, for I am sure that no one has ever stood at the crest
of Niagara Falls with any sort of speedometer. I took a number from a site.
I did find one bit of information that may apply more broadly. At
www.usbr.gov/lc/hooverdam/faqs/tunlfaqs.html I found, with a head of about
500':

 ... Maximum water velocity in the spillway tunnels is about 175 feet per
second, ...
Which should come out about 120 mph. This is not an open stream, but the
head should make a difference anywhere it's encountered.
 
But now I've got other things to do, and there are those getting bored, so
I'll quit this line.
