This isn't a smartalec answer. Rivers flow downhill. You only need to know the terrain and can determine what direction they flow.

Water will always seek the path of least resistance. It will go around or under rather than up and over whenever possible. Confronted with a mountain chain or even a small ridge, the river will turn and flow parallel to the blocking feature unless or until it is able to erode a path across it. The composition of the terrain determines whether or not this is possible. Hard rocks allow little, or only very slow erosion. Sand, gravel and dirt are easily eroded and the river will make its path through these much more easily.

Water in nature never flows very far in a straight line. If you look at a map, you see that rivers, creeks, and streams twist and turn on their way seaward, even where there are no obstacles in their path. This twisting and turning is called meandering and develops not only in response to large obstacles, but also in response to very subtle differences in terrain, even to the the ease of flow over one grain of sand versus another. Slight deviations become magnified and the meander appears.

The Nile (Arabic: النيل‎, translit: an-nīl, Ancient Egyptian iteru) is a major north-flowing river in Africa, generally regarded as the longest river on Earth, though some sources claim the Amazon in South America is longer.[1] The Nile has two major tributaries, the White Nile and Blue Nile, the latter being the source of most of the Nile's water and fertile soil, but the former being the longer of the two. The White Nile rises in the Great Lakes region of central Africa, with the most distant source in southern Rwanda 2°16′55.92″S, 29°19′52.32″E, and flows north from there through Tanzania, Lake Victoria, Uganda and southern Sudan, while the Blue Nile starts at Lake Tana in Ethiopia, flowing into Sudan from the southeast. The two rivers meet near the Sudanese capital Khartoum.

The northern section of the river flows almost entirely through desert, from Sudan into Egypt, a country whose civilization has depended on the river since ancient times. Most of the population of Egypt and all of its cities, with the exception of those near the coast, lie along those parts of the Nile valley north of Aswan; and nearly all the cultural and historical sites of Ancient Egypt are found along the banks of the river.

The Nile ends in a large delta that empties into the Mediterranean Sea.

The Nile flows north and is one of the few that do in the world. The New River flows north in the US.

It rises south of the equator and flows northward through northeastern Africa to drain into the Mediterranean Sea. It has a length of about 4,132 miles (6,650 kilometres) and drains an area estimated at 1,293,000 square miles (3,349,000 square kilometres).
