Why do mountains rise?
Why are volcanos hot?
Why are plains flat?
Why is the earth round?
Who is Sylvia?

I was referring to the title of a song by Schubert. But, I'll take your reply instead.

the neat thing is that we learn from one another,
about Franz Peter Schubert and Sylvia (plus, do you remember Ian and
Sylvia? ... https://video.search.yahoo.com/video/pla...)
-- good innocent fun!!! -- j
p.s. that's a live version, not the "hit."
she was a year ahead of me in Everly Brothers High
and befriended me even though I was a nerd.
she was a very sexy woman. . remember? -- j
p.s. west high in knoxville did see the E Bros
for awhile, before they were famous.

Ground varies in hardness and consistency and water will flow to the lowest point and carve the softest ground. When water crests due to flooding, water will flow to the lowest point, causing gouges in the ground making a channel/path to flow...pretty much common sense.
BUT here is a question.
What three rivers in the world flow North?
Lots of them. Its downhill that matters, not compass direction.
flow north into the Arctic ocean. -- j
1) Nile in Egypt
2) St. John in Florida
3) Monongahela in Pittsburgh, PA
They key to the question is not that just s small portion flows north but the River Starts in the south flows and ends in the north.
And lack of accurate description... is "flowing north" defined by 'mouth is north of source'? Implicit, but not spelled out... I'm a little disappointed...
to wit...
THE FACTS: Unless the land it totally flat, rivers of water run downhill. The vast percentage of rivers on the planet flow in
a southerly direction because the source (usually in the mountains) is to the north of the mouth.
If the source of a river is at a higher elevation than the mouth, that river will run from the source to the mouth. However,
if that (higher) source is to the south of the mouth, that river will then flow to the north (downhill).
Below is a partial list of rivers (length listed when known) that do just that. We haven't listed rivers that run to the northwest,
or rivers that don't meet the exact requirements...

--"is"? and "You're shitting me, right?"
:)
And why not beavers? Because they don't tend to build their homes anywhere near slow-moving streams or rivers... they CREATE the slow-moving waters with their dams.
How do they know where to put their dams to make the pent-up mini-lake behind their dam? Some time back I read about the answer: Beavers begin to block a stream where it's NOISIEST... where it's tumbling downhill the steepest. Building a dam there will tend to create a nice little lake upstream and it's certainly easier for a beaver to find the noisiest part of a stream than to figure out any other prime location.
Notice how even humans put dams across steep, fast-moving rivers... you won't find many hydroelectric power centers on the Mississippi, for example.. :)
Loved my 10th-grade Earth Science class... 1960-1961.

Only around 2,000 of the nation’s 79,000 dams are equipped with generators, leaving a great deal of potential on the table, say hydropower advocates. Most of the locks and dams offer “low head” hydropower where the differential between the height of river before and after the dam is 30 feet or less. They are sometimes called “run of the river” power plants because they do not stop flows or create pooling upstream.
Many are near potential consumers but the ancillary infrastructure to tie them into even a substation grid and protect them and the grid from each other just might price them out of the potential market for a while... or forever.
Having something 'available' doesn't mean anyone might be willing to 'buy it at the market price.'
But hey, I'm just a guy with engineering and marketing background... what do _I_ know? Let's leave those tough decisions up to local and state Legislatures, right?

Tracing the effects from a butterfly's wing-flap to a major storm sounds pretty tough, but a good-sized pebble in a stream can have immediate and 'somewhat predictable' or at least traceable effects.
The 'butterfly effect' is cute, but with so many butterflies (and moths and such) in the world, I'd put its Predictive Value at somewhere VERY close to Zero, (if not lower.) :)
I resent being dissed as just ONE of the most famous meanderers here because my meandering ways should surely tag me as the BEST greatest meander makers of all time.
I was once a libtard but am one no longer.
I guess that explains it.
Neither am I a muskrat.
I'm not a beaver or a girl either.
Speaking of girls, one once said I reminded her of a bear.
That was in 1980 when I lived in Mississippi for 6 months.
I think an allosaur is cooler, though.
Acting like one, too.
Yeah.
