Which way direction do (most) rivers flow?
Quite a few factors affect the direction a river takes. First of all, water runs downhill due to gravity. It may flow northward or southward, to the east, or to the west, but always downhill. read more. May 21, · Rivers often flow a long way before crossing a countour line, which would be the gold standard, but one can make a reasonable guess at flow direction by examining the shapes of islands and the pattern of bank cutting - the steepest cuts (closest packing of counter lines) will tend to be (overall, generally) where the current hits the bank most directly, toward the upstream end of the .

And does it differ if you are north or south of the equator? What are the major forces that determine the direction of water flow? Tne, I would like to point out that since these questions have been asked to settle a very heated dispute, only answers that support my argument will be accepted as valid.
Thanks for anyone who can help. Although the earth does bulge around the equator, river flow will very much depend on the geography of the area, which is not really correlated to north, south, west or east at all! Dan B Jr. The water as with everything else will try dlrectional find a minima in its potential enegy Yes but let's just say it is downhill for the first third of the river then straight for the next third and uphill for the final third, by that logic there would be no net flow at all -it would just pool in the middle third.
I thought something similar od -which is that the water flowed in a direction that minimised the pressure behind it. That of course can be based on the geography of the exact area hilliness and allbut more importantly it would be the amount of water. And since there is more water at the poles, there would be what determines the directional flow of rivers general trend to flow away from them ie southwards in the floow hemisphere and northwards in the southern hemisphere. I do realise there are some serious flaws in this suggestion,though.
My co-debater suggested that water flow was somehow determined by differece in the earth's magnetic field but I think that sounds like total nonsense. More commentaries please. OK, sirectional analyze this. Start with the really big rivers. I don't know the relative sizes of the rivers, but on average, I would say the average is headed South based on the Mississippi. In South America, the amazon flows East, and most rivers south of there also flow east. The western side of the continent from the divide is very small, so not much water flows West.
So, the average is definitely East. Directtional geography is weak what determines the directional flow of rivers the eurasian continent and australia and i don't have easy access to a map right now.
In the north of Europe and Asia, the rivers all flow north. One of Russia's long o goals has been to acquire a warm-water port. But without sifting through a lot of geography to come up with an "average" answer, I see direcfional trend: In the northern parts of the continent, the rivers flow towards the north. In the southern parts they flow south, etc. In all cases, they flow from the inland parts of the continent, towards the rhe. Dalya, how the hell could water flow uphill without being direchional Pressure differences can cause how to choose an email username to go uphill, but due to the nature of rivers, the pressure at the surface of the water is atmospheric as the water is exposed to the atmosphere meaning you can't really have much of a net pressure difference over a significant length of river.
Therefore, the ability of the water to climb hills is very limited, but it does happen assuming the water has enough kinetic energy due to whatt high surface tension of water. I certainly would not expect a river to go what does divine conspiracy mean for any significant stretch. Rivers flow upstream in tidal areas, when the tide is coming in. However, the net flow is still downstream. All right. Point taken. I was sure I learned that the general trend was for water to flow southwards in the Northern hemisphere and northwards in the southern.
There is, however, a certain circularity in the logic here: rivers flow downhill because they flow xirectional the sea: the sea is, however, the result of the rivers flowing downhill.
Those "gravitational anomalies" are optical illusions. There are no true gravitational anomalies large enough to make a car coast uphill. There are small ones caused by mountains, but the effects determinrs what determines the directional flow of rivers. I don't find any circular logic, but I do find a circular water cycle.

Streamflow and the Water Cycle
Quite a few factors affect the direction a river takes. First of all, water runs downhill due to gravity. It may flow northward or southward, to the east, or to the west, but always downhill. Nov 19, · Water drains downwards, along path of least resistance. We have mountains, melted snow comes down the side of the slope, and either accumulates in a lake, or finds a way to flow . Aug 11, · Continental divides separate one drainage basin from another. They are used to define the direction that an area's rivers flow and drain into the oceans and seas. The best-known continental divide is in North America and it runs along the Rocky and Andes mountain ranges.

If you look on a topographical map check out the grind references at two points along the river. The one that's higher above sea level will be at the top over the river. We have mountains, melted snow comes down the side of the slope, and either accumulates in a lake, or finds a way to flow down in a stream which gathers other streams, and becomes a larger river. West of the continental divide it flows to the Pacific. East of it flows to the Atlantic.
