Igcse Geography River Processes And Landforms Essay Aufsatz A river transports, erodes, or deposits sediment (load). river processes – erosion, transportation and deposition. 1) erosion involves the wearing away of rock and soil from the river bed and also banks. this way the river can get deeper and or wider. there exist four main types of erosion.

Ib Geography Stream Processes Landforms вђ Geo41 The process of erosion. erosion is the wearing away of surfaces there are four erosion processes which change the shape of the river channel: hydraulic action abrasion attrition corrosion (solution) types of erosion. erosion can be mainly vertical or lateral: vertical erosion is dominant in the upper course of rivers. Processes of river erosion. hydraulic action: this is the sheer force of the water hitting the river banks. fast flowing water exerts pressure on the bank’s sides and bed, leading to erosion. when water infiltrates cracks and then suddenly moves, it can dislodge chunks of the bank or bed. abrasion (or corrasion): when the river’s load (the. The long profile of a river shows the changes in the river gradient from the source to the mouth. most long profiles have a concave shape with similar characteristics: the source is usually in an upland area. the upper course of the river includes areas which are steep with uneven surfaces. in the middle course, the gradient decreases. Summary. the river’s long profile depicts its gradient from source to mouth, transitioning from steep areas to gentler plains, while the cross profile shows the river’s width, depth, and valley height at a specific point. irregularities in profiles, called “knick points”, result from factors like geological variances, load differences.
