I'm missing something here. The source amount of water is the same -- it is just that in one case it comes by massively, but for a short period. In the other case it comes by less massively, but over a far longer period of time. Shouldn't the erosion be the same. Or rather, shouldn't massive waters cut wide and shallow, while reduced waters over longer times cut narrow and deep?

I would suggest a source other than Answer's In Genesis if you want to be taken seriously.

Like what, Don Lindsay or Talk Origins?

I especially enjoyed the second link..

The main reason they don't think the canyon came from Noah's Flood: there was no single world-wide flood.

[PatrickHenry]

From the article:
One company, Another Viewpoint, offers trips through the canyon explaining its features as the result of Noah's flood.

Man, I'd love to see a transcript of the lecture. What happens when some kid on the tour asks: "If the flood was worldwide, why doesn't the whole world have hundreds of places that look like the Grand Canyon?"

Stream channels begin as V-shaped troughs, but many factors affect final streambed morphology.

In non-mountainous areas, stream flow is not tighty constrained and can spread out during floods. Suspended particles (bedload) are dropped as flow turbulence decreases as the flow spreads outside riverbanks, resulting in wide, more gently sloping floodplains.

In mountainous areas where flow is greatly restricted by mountain walls, downcutting is more rapid as suspended bedload scours the bottom of the stream channel, producing steeper stream valley walls such as those seen in the Grand Canyon.

new data indicating the canyon's Inner Gorge may be no more than 700,000 years old, much younger than earlier estimates of 3 million to 5 million years, said Robert Webb, a research geologist with USGS.

Damn!
I wonder how humans 700,00 years ago managed to mobilize and abuse the environment to that extent...
People are no damn good; a cancer on the planet.

They probly managed that while they were extinctioning the dinosaurs and producing massive clouds of greenhouse gases.
They all were homophobe and sexist and oh my gawd... probably smokers, the bunch of them.
Bah humbug.

I just might go extinction myself soon if this persists.
Shocking..

The Grand Canyon would have been in violation of EPA non-point-source regulations had the EPA existed eons ago.

And you know who those as****** bureaucrats would have fined for the violation!

Correct. Any taxpayer actually producing and holding real jobs.
Nothing ever changes.

A lake with 37 times that much water would have covered quite and area, too much IMO to be contained by a dam at one end.

?????????????????

I hope you're not an engineer. Hydrostatic pressure on the dam is the same whether the lake behind the dam is 1000 feet or 1000 miles, for any given height.

"The feds are just pissed because people have fun there."

Not just the feds but the green freaks themselves. They are comparable to a quote associated with the Puritans. They are worried that somewhere, someone is having a good time.

I am a hydrolic engineer specializing in dam building. (Not really)

I was speaking of the expanse of so much water finding another way out, even between mountain ranges, not the ability of a dam to contain it.

[Mind-numbed Robot]

It is obvious that I did not explain my point very well. What I was attempting to say is that water of that quantity would be so spread out that there would be no choke point, it would escape somewhere, even between mountain ranges.

Good. There's no "o" in "hydraulic."

[Mind-numbed Robot]

There's no "o" in "hydraulic."

I know that! Of course, I know that!! I learned that while becoming a inganeer, like I said. :-)
