The longest river in the world flows north, the Nile. \n\nThe Rhine ends up northerly, though if I am not mistaken, farther inland, flows predominantly westerly.\n\nThose are the main big ones, though just about any river that empties into a body of water north of the landmass it is on, is going to, out of necessity, flow generally northerly. Such rivers would be in Canada, Alaska, and Russia emptying into the Arctic Ocean. Northern African countries with rivers emptying in to the Med, would be flowing north, though those countries are predominanty desert, so the rivers would probably not be much.\n\nThere are rivers in northern South America, in Columbia and Venezuela that would be flowing into the southern Carribean Sea on a northerly course.\n\nWith the exception of the Nile, most rivers that flow north are not in areas that attract that much attention. Afterall, how much activity is there on the Arctic Ice Pack to draw attention to frozen rivers emptying into it.\n\nIt is not a matter of more rivers flowing south, but rather most rivers THAT GET ATTENTION flow in a direction other than north. (Afterall, the Amazon River has a mostly easterly course.)

Topography is the word you want. Combine Topography with river and throw it into a search engine and things like this Wikipedia article should fall out.  Happy hunting.

Unless the land it totally flat, rivers of water run downhill. The vast percentage of rivers on the planet flow in a southerly direction because the source (usually in the mountains) is to the north of the mouth. \nIf the source of a river is at a higher elevation than the mouth, that river will run from the source to the mouth. However, if that (higher) source is to the south of the mouth, that river will then flow to the north (downhill).

yes.  a river will flow from higher terrain to lower terrain, independent of the compass direction.  two rivers near where i live that flow north are the Red River of the north (North Dakota/ Minnesota border) and the Nemadji River (northwest Wisconsin).

Cnatthink of one but try some geography sites\n\nold rivers have lots of ox bows and meanders from sidecutting \n\nnewer rivers are generally straighter and dont have as large floodplain and also maybe more braided

Rivers empty into major bodies of water...tributaries empty into rivers

If you're referring to a reverse flow due to natural OR artificial causes, the most noteworthy is the North fork of the South Branch of the Chicago River. This was reversed to have sewage flow down the Great Lakes/Mississippi waterway. The North Branch and South Fork of the South Branch were unaffected.\n\nSpeaking only of natural phenomena, there would, I am sure, be many. One I know of for sure is the Mekong, which is so close to sea level that the twice daily tides cause it to reverse flow and actually flow backward in some areas.

no, there are many freshwater rivers that are tidal.  in fact, i dont think i know of any rivers that arent freshwater (except polluted one)\n\nmany rivers that empty into the ocean would be considered tidal.\n\nwhere it empties, as the tide rises, water will rise too, and in many instances can change the current of the river and make it flow in reverse.  \n\nif you close up that opening a little, say with a bridge, the water will flow extra fast and is a very interesting ride on a canoe or kayak.  its a popular attraction at many places in maine i know, where you can ride around in the rapids that form on one side of the bridge and then slowly transitioning into rapids on the other side.

South America's Amazon River is the world's largest because it carries more water to the sea than any other river. The Amazon's discharge at its mouth is approximately 7 million cubic feet per second.\nThe Amazon is the world's second longest river as well, coming in just a tad shorter than the Nile River at 4,049 miles (6,516 kilometers) long.

A river is the main body of water, the tributaries are smaller streams etc that branch off it or into it...\n\nLike a tree... the trunk is the river, the branches are tributaries..

World's Shortest River\n\nThe Roe River is recognized by the Guinness Book of World Records as the world's shortest river. The Roe flows 200 feet between Giant Springs and the Missouri River near Great Falls. The Roe River competes with the D River in Lincoln City, Oregon for the title of the shortest river. Both rivers have been measured on different occasions, with lengths varying from 58 feet to 200 feet. Schoolchildren in Great Falls campaigned successfully to have the Roe River placed in the Guinness Book of World Records. \n\nThe source of the Roe River, Giant Springs, is the largest freshwater spring in the United States. The longest river in the state is the Missouri River. The Missouri flows 1,029 miles, from Three Forks to the North Dakota border.

The longest river in the world,Nile,begins from the equator line and flows in the northerly direction through the countries of Burundi,Sudan,etc and goes into the Mediterranean Sea in Egypt.\n   Nile starts off as two rivers namely The Blue Nile and The White Nile.\n   The Blue Nile begins in Lake Victoria and flows upward towards Sudan and joins the White Nile at Sudan's capital,Khartoum.\n   The White Nile begins in eastern Sudan.It contains many falls and rapids.It calms down when it meets with the Blue Nile at Khartoum.\n   The Nile river is the main source of irrigation for the Egyptian agriculture.The annual floods brought arid soil from the African continent to the Egyptian plains.After the Aswan Dam was built, the flooding have had been controlled.\n   The Ancient Egyptian Civilization flourished due to the Nile and has been the heart of the ancient religion of Egypt.
