Because the water has more space to move. Just like pinching a garden hose makes the water go faster, because the same volume moves through less space permalink fedilink source parent hideshow 2 child comments replies: [–] Hazel@piefed.blahaj.zone 3 points 6 months ago (2 children) Hmm, I think it's fast, deep and narrow, or slow, shallow and wide. Don't ask me why width and depth don't act the same though. permalink fedilink source parent hideshow 4 child comments replies: [–] faythofdragons@slrpnk.net 4 points 6 months ago There's a lot that goes into river velocities. What slows rivers down is primarily friction, so a wide, shallow channel will move slower because there's a lot of drag along the bottom and banks. Having debris, like plants, rocks, or boulders also creates more drag to slow the water down. A deep river will move faster, because the depth makes a 'fast lane' for water to slip over/between the slower water along the bottom and banks. permalink fedilink source parent [–] IndolentRoshi@sh.itjust.works 3 points 6 months ago Gravity, I reckon permalink fedilink source parent
