    The three main processes of a river. As the river speed gets more, the erosion starts to happen.When the speed is low, then lots od deposition happens. The transportatio shows that as the rocks get bigger, the less transportation happens.

    three main processes of a river and how they happen. Erosion happens when its fast flowing, deposition when its slow flowing and transportation always happens but different sizes of things are transported depneding on the speed

    This graph shows the 3 main processes of a river, transportation, erosion and deposition. The lower the velocity the more deposition will take place, the higher the velocity the more erosion will take place. Also the larger the sediment the higher the velocity has to be to transport it, otherwise it is deposited.

    the graph shows the hgher the velocity the more likely the river will cause erosion and the lower the velocity the more likely the river will cause deposition. It also shows that if the higher the velocity the more it will carry, such as things like rocks whereas the slower the velocity, it will only transport small objects such as clay and silt.

    this graph shows that the higher the volocity the more erosion there will be and the lower volocity the the more depostion there will be.

    As the river speeds up, there is less deposition and transportation and more erosion occuring. also you can see that the size of the sediment in the river also has an effect on these processes - bigger sediment means more deposition and less transportation because the river cannot carry it.

    the graph shows that pebbles and sand are deposited because the flow of the water is not fast enough to carry them. whereas silt and clay are transported down the river as they are lighter. the faster the velocity the more erosion takes place

    Materials such as silt and clay are light and so can be carried easily in the flow of the river, however this material can cause erosion when carried in a fast flowing river. Sand is denser and so can be deposited at low speeds onto the river bed, at fast flow this can cause ots of erosion but in mid-flow the sediment is transported along the river. Very heavy sediment such as pebbles and boulders mean that its hard for the river to carry the material and so is frequently deposited along each c=stage of the river, if the water can flow fast ebough and deep enough then the heavier sediment can can cause erosion but mainly it is deposited. This is all supported by the above graph.

    the speed of the river depends on whether transportation or erosion will take place. if the size of the sedement is as small as clay or silt, transportation will still take place, if sand or pebbles then deposition will occur.as the speed increases sand and pebbles can also be transported.

    shows that; the faster the speed of the river, depends on whether the rocks; erode, get transported, or deposited. it takes into account the size of the rocks and uses a double logarithmic scale, to indicate the impact of the speed and rock type. e.g. a 10mm pebble travelling at a velocity of 1000cms/sec would mean its erosion

    how do you tell the difference between a can of tomato soup and a can of chicken soup???
