This is simply defined as the overall spatial arrangement of streams in an area. The point at which the main rivers are joined together by other smaller rivers is called tributaries. Therefore, the main river and all its tributaries together form a river system. Note that the area that is drained by these rivers and …

Flood Plain Flood Plain is wide, nearly flat or gently undulating plains alluviums in the lower courses of rivers. They are made up of sediments deposited on the lowland areas (boundary) of the river valley. They are usually very fertile agricultural land. Flood plain occurs when a river overflows its banks. Ox-Bow Lakes or Cut-off …
Meander: This is formed when there is an excess of stream energy at sections of the stream channel where the slope exceeds what is required for transporting the stream level. Due to the excess stream energy, as caused by hard objects, it prevents a river from its normal course thus resulting to the formation of …
V-shaped Valley: This is formed as a result of vertical erosion of a river, which is deepened by vertical corrosion, and widened by weathering and mass movement. Gorges: This is formed especially when a river follows a line of weakness such as a fault or down cutting with little or no valley widening. Canyons: A …
Upper course Middle Course Lower course UPPER COURSE: This is also known as youthful stage. The upper course of a river starts from the source near the watershed as the water flows very swiftly due to the steepness of slope. This course of river is predicated by the action of erosion, which in the end …
