The capacity of a river is the total load a river can transport at a given point deposition deposition is the process of the eroded material being dropped. River processes provides a comprehensive synthesis of current knowledge about physical processes in alluvial channels, with an emphasis on the recent work on flow-bed-sediment transport interactions it is intended primarily for undergraduate students interested in fluvial studies as part of physical geography, earth sciences, environmental.
A thorough insight into erosional and transport processes and river landforms including: waterfalls, potholes, meanders, oxbow lakes, deltas, levees terminology source: the starting point of a river, the place from which a river flows. Rivers have a lot of energy and because they have energy, they do stuff the obvious things rivers do with their energy is flow but, besides this, they also transport load, erode load and erode the channel through which they flow. River processes erosion, transportation and deposition all occur in a river moving from the upper course to the lower course, the rates of erosion, transportation and deposition change.
Four main types exist: 1 corrasion when a river picks up material and then rubs it against its bed and banks erosion occurs by the process of abrasion, and is most effective during times of flood.

River capture zimsec o level geography notes: river capture this is a process where one river captures the headwaters on a nearby stream this can occur due to several reasons viz. The five main processes in which river erosion occurs hydraulic action - the pressure of the water breaks rock and soil particles away from the river bed and bankhydraulic action is strongest where water movement is most intense such as at waterfalls, and during floods.
A river's erosion, transport and deposition depends on the flow of water in its channel this flow is determined by several factors viz: the energy which is provided by gravity and is affected directly by they gradient of the river's bed the steeper the slope the more energy a river has. river processes (page 6-7) erosion can affect the length, depth and width of a river vertical erosion deepens river channels it happens in the upper stages of a river lateral erosion makes the river wide. As a river flows along its course it undertakes 3 main processes which together help to shape the river channel and the surrounding valley these processes are erosion, transport and deposition. River processes is a creditable addition to the literature all the illustrations are clear and well drawnriver processes will become a popular book that is required reading in all fluvial geomorphology courses empasising the interactions between water flow and sediment transport.

Describes the processes of erosion, transport, and deposition by running water. As we have noted already the processes and interaction of the river with its physical environment changes ast it flows from source to mouth a key influencing factor is the long river profile, illustrated in the diagram to the right. A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river in some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water.

Terrestrial animations this set of animations from the community surface dynamics modeling system (csdms) group contains 16 movies of various river processes movies include meander formation, floodplain evolution, floods, river engineering, landscape evolution, dams and more. There are three main processes a river does to shape the landscape: erosion, transportation and deposition different processes create different river landforms contents[show] erosion vertical vs lateral erosion vertical erosion occurs in the upper course of the river, forming features like.
