Rivers constitute a major natural phenomena found on the surface of the earth. They have unique patterns and systems that perfectly fit in the geographical grid. One can establish the facts behind the formation of rivers and the important part they play in the ecosystem by carefully studying their features. However, the topic needs more research to know the reasons behind the uniqueness portrayed by each river.
As the river flows, it cuts rocks which it carries them down its course and grinds them as it moves farther to forms sediments. When the river enters a relatively flat ground, it slows down resulting in sedimentation. This process is common in the plains where the river spreads over a wider area to form a U-shaped valley. Due to the

The second classification of rivers relies on the biotic composition of their waters. Rivers in this category range from oligotrophic (unpolluted) to the extremes of eutrophic (polluted) rivers. The zonation procedure divides a river into three distinct parts; that is, the crenon, rhithron, and potamon. The crenon represents the superior part of the river differentiated by high speed, low temperatures, and low oxygen content. Additionally, the crenon forms a hypocrenon and a eucrenon. The rhithron follows after the crenon (middle part of the river) with relatively increased levels of oxygen, turbulent flow, and cool temperatures. Finally, the potamon represents the lower part of the river distinguished by slow speed, low concentration of oxygen, warm temperatures and sand-covered river beds (Green 220).
River Flow and Drainage Patterns The flow of the river is normally determined by the force of gravity. In this regard, the flow can take different paths and directions. The volumetric discharge rate determines the water volume flowing via a specific point of the river per unit time. The unit assigned to this measure is cubic metres per second. The uses of rivers are enormous depending on their locality, flow rate, and water volume. Large scale irrigation and many production processes depend on river water. The rivers form a crucial part of the hydrological cycle that determines the climate of a given region. Additionally,
