Stormwater is also a resource and important as the world's human population demand exceeds the availability of readily available water. Techniques of storm water harvesting with point source water management and purification can potentially make urban environments self-sustaining in terms of water.
Rivers flow downhill to sea level (generally speaking; some end in other bodies of water or join another rver). They flow with gravity from a higher elevation to a lower. The Nile rises on the western flank of the Great Rift Valley (many people consider Lake Victoria to be the source) and the Blue Nile joins the White Nile at Khartoum. The land falls away towards the north, thus the river flows north until it reaches the Mediterranean Sea at the Nile Delta. Direction of flow of a river is determined by elevation of the drainage basin, not geographical (North, South etc.) direction. http://en.wikipedia.org/wiki/Nile#Course.
Answers. Best Answer: The Nile river was formed the same way every other river was formed. From smaller streams of water merging together into a river. Rivers are the results of overflowing lakes, or runoff from mountains.hen it eventually empties into the ocean. Sediment that settles at the mouth of the river meeting the ocean clogs up the water flow and creates a delta. For the Nile specifically, it is formed from the merging of two tributaries, the White Nile and Blue Nile.
