    Just ONE of the most famous?
    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.

    That was a good learning video. Enjoyed it thoroughly. Thanks for posting freedomforall!

    Just offhand, the Rhine, Elbe, and Oder in Germany. The Vistula in Poland. The Meuse in Belgium/Netherlands. All flow into either the North Sea or Baltic and begin well to the south.

    Ah, maybe, Randy, but I wouldn't jump to that one.
    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.) :)

    Wood, I've wondered about that, too. I live near a man-made lake which has a frequent overflow. My suspicion is that most such potential energy sources aren't economical because of the investments and resources needed to build, connect and maintain such energy supplies.

    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?
    :)

    Congress should pass a bill against skipping rocks. (: )

    I think there are way more than that. For instance, the MacKenzie-Peace River in Canada dumps into the Arctic Ocean.

    Only 3 Rivers flow north.
    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.

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

    "What three rivers in the world flow North?"
    Lots of them. Its downhill that matters, not compass direction.

    They could have if they had the forethought.

    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.

    It is a thing called "Path of least resistance."

    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?

    Since they cause global stream-braiding, I will never again vote for a muskrat.

    Who needs muskrats? The first pebble that falls into the stream (or the first dead animal that blocks a bit of flow near the bank) will start the same chain of events.

    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.

    Cheers!

    Waterfront property, which if you own it long enough will be eventually be spread across silt beds, way downstream ;)

    The intelligent designer of physical properties of our universe must have been part real estate agent. Lots more water front property ;^)

    +10. It explains us when we meander and they chose muskrats instead of beavers. Beavers are always mentioned in these kind of videos. let's keep meandering!
