Tidal bores are your friend! Just search for that term in any internet video search engine to see what I mean.

Heh yeah, I live here next to the River Severn which is the longest river in UK and that wedge shape bit bottom left dividing England from Wales. It also happens to be the second largest tidal region in the world and has regular bores where a lot of people get out for to watch - most in wet suits...

Also like to add the NASA GES geomorphology site. specific to this discussion are the Fluvial Landforms from space (photos plus diagrams):

Hi i have a question that confuses me a bit, i was hand drawing a underground dwarven stronghold. on one side of the mountain i have a valley with a river above the ground (between to mountains), i understand that alot of the water will go into that river due to the catchment area. as i have been drawing further and further down into the mountain i thought would i b able to have like a underground lake or would the catchment area of the river stop the lake from filling up. there not right next to eachother but the river is on the side of the mountain and the lake im thinking of will b almost dead center under it. i thought i would ask b4 i actually had a go at drawing it in.
thx for any help and i do apologize if this isnt the right thread/topic to ask.
I would assume that you could have an underground lake anywhere you want provided that there is rock preventing them from joining together in a vital area.

I was looking for some visual aids for describing some terrain to RPG players, and my search was 'Canadian Shield Region'
And I came across This river system.
I thought you guys might find it interesting. If I saw someone draw that on a map I would think it was very 'unrealistic'.
Its with a bunch of other pics in an article on craters, which you can find HERE.

Very cool! I'd probably call it out, too, if only to get the story behind its formation. I'm sure nobody would put that on a map without a story to go with it.

Yeah, that's from a crater. I saw it in one of those science shows that I'm always watching on the Science Channel...I think was called "How the earth was made" and it was in one of the episodes. Might be a different tv series, I can't keep them all straight in my head. Normally you'd think that the crater edges would prevent a ring river but the mound-in-the-middle resulting from the impact was very dense so it eroded very slowly while the edges were closer to normal dirt so they eroded faster. There's a few others like this in Asia and Central America if I remember right.

Texas is a bad example of lake formation, unless you have a race of sentient beavers in your fantasy world . All lakes in Texas are artificial save one, Caddo Lake, and we dammed that one for good measure, too. As for crazy forking Texas rivers, they never split after joining up and all flow to the gulf or the Rio Grand then to the gulf. Most of the time when something violates a rule its because of either heavy rainfall/flooding, which will sort itself out quickly, or because man stepped in a messed with things (i.e. the Chicago river flowing the wrong direction)
