Why do some rivers run uphill?

Answer 1

Responses without sources are not answers, just opinions.

A tidal bore (or just bore, or eagre) is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travel up a river or narrow bay against the direction of the current. As such, it is a true tidal wave (not to be confused with a tsunami).

Answer 2

Of course water doesn't run uphill, but if an area of land is below high tide level and rivers drain from it into the sea, then it can appear to be flowing uphill - areas of the Somerset Levels in England are below sea level at a Spring Tide but the rivers don't run backwards but if they're in full flow because of heavy rain they will flood. Also, over a long distance the source of a river can be closer to the Earth's centre than at the point it reaches the sea because the Earth bulges at the Equator, but because of the increased mass of the Earth at the sea end, water is drawn there by gravity and in that sense it is flowing uphill.

Answer 3

Rivers or water does not run uphill..gravity pulls things down....water flows according to the land relief or the elevations... you may be thinking of a map that shows rivers running north or "up" such as the Nile River in Egypt, obviusly it is the way we look at it on the map, there is no top or bottom.....

Answer 4

Sorry,No river or any mass of water run "uphill".
The topography of the land determines which direction the river flows ie. east/west ,north/south etc.Never "uphill".
To the human eye the land/area of flow may seem to be "uphill"
but it could well be a low lying arear etc.etc.etc

Answer 5

Water will go from the highest point to the lowest point. So, along the route of a river between source and final destination, if the course seems to gain altitude, it doesn't matter.

Ever try to drain water out of a fish tank? Take a hose, completely submerge it into the fish tank. Then (with your finger over the hole at one end) take that end and put it into a sink at a lower level than the surface of the water level in the tank. Water will flow up over the side of the tank and down into the sink. As long as there is mass to push water along and make it flow, it can flow up for awhile.

Answer 6

No river runs uphill, they may appear to do so because of an optical illusion, however, basic physics tells us water does not run uphill. There are places in the U.K., ( and probably elsewhere in the world), where you can stop your car on what appears to be an uphill slope and it will apparently run, "uphill". if you just release the brake, optical illusion again! NEVER TRUST YOUR EYES, THEY ARE ALWAYS SUBJECT TO REALITY CHECKS!

Answer 7

which one does? i have heard of some running north, but uphill? that would be defying the law of nature. maybe a local tide in a river connected to the sea would cause it to move uphill locally and temporarily near its mouth, but i am not very sure.

Answer 8

It's called gravity. Everything is attracted to everything else. Water in rivers is generally attracted towards the earth as it is by far te largest object in any proximity. The centre of the earths mass is not supprisingly in the core, thus all wather is pulled "downwards" towards the earths core, thus no river run uphill, without the aide of pumping stations.

Answer 9

in tidal areas it is just the tise coming in. but in fresh water its different. water coming down hill can gather enough energy to push it uphill(bit like a rollercoaster) for a few miles. also the river tyne in runs up hill its entire length due to water being sucked by megavacuum forces created by high-level eparoration at the source.

Answer 10

.they was once an earthquake that was so powerful that it reversed the flow of the Missisipi,but it still didnt run uphill......and if someone told you that there's a river that goes uphill, and actually believed it,you must be really gullible....hey did you no gullible isnt in the dictionary?LOL!
