Transportation in the upper course of a river

Gradient of the channel. The gradient of the channel determines a rivers ability to erode, transport and deposit its load. The upper course of a river is associated with steep gradients therefore a lot of velocity and energy and therefore river erosion and transportation takes place in the upper course.A river changes with increasing distance downstream from its source towards its mouth. It moves through its upper course, to its midcourse and finally into its lower course. Steep valley sides are typical of a river's upper course in upland areas. The valley here has steep sides and the valley bottom is narrow. transportation in the upper course of a river

Technically, the reason to why does a river change its course lies in this basic physical quantity that is gradient or slope of the surface. Wherever the river finds a greater gradient it tends to switch to that. Rivers generally don't change course in the upper or mountainous course. Changing of course takes place mostly in the lower

River landscape. Vshaped valley produced in the upper course because the river cuts down faster than the surrounding slopes are eroded. Meander the river starts to erode from side to side. River cliff the river moves faster on the outside of the bend and cuts into the valley side. The erosion undercuts the ground causing it to collapse, leaving a cliff. The upper course or mountain course: The down cutting of the river deepens the valley whereas the side wash make the valley sloping upward away from the river. As the slope of the land is steeper and the velocity higher in mountain, vertical erosion or down cutting of a river far exceeds lateral erosion.transportation in the upper course of a river Erosion and transportation are the main activities of a river in the upper course. A river has a deep and narrow channel in this stage. Moreover, some of the rocks over which a river flows are very hard, while the others are soft.

River Transportation. Suspension fine light material is carried along in the water. Saltation small pebbles and stones are bounced along the river bed. Traction large boulders and rocks are rolled along the river bed. The video below shows the movement of sediment in a river. Notice the different types of processes transportation in the upper course of a river Vertical erosion is greatest in the upper course of a river. As the result of this typical features include steep valley sides, interlocking spurs, rapids, gorges and waterfalls. When a river runs over alternating layers of hard and soft rock, rapids and waterfalls may form. How can the answer be improved? The long profile is a graph of a river that marks the change in altitude from the upper course to its lower course. All along its course, the river uses energy to carry out erosion, transport and deposition of sediment. This energy is produced when water flows down a slope.
