As the water flow progresses downstream, the river channel should become wider and deeper due to lateral and vertical erosion

Extracts from this document...

Introduction

Hypotheses I am testing that this is how the following hypotheses will change as you progress downstream: * The river will get wider and deeper * The velocity will increase * The discharge will increase * The gradient will decrease I will also test the following hypothesis: * Sediment size will decrease Predictions As the water flow progresses downstream, the river channel should become wider and deeper due to lateral and vertical erosion. ...read more.

Middle

The rivers discharge will also increase because of the rivers tributaries contributing to the water flow of the main river. These tributaries help collect water from inside the river basin and carry it to the main river where it joins at a confluence. The gradient of the river will decrease as the water flows further down the river. This is because the gradient is very steep in the Upper Course as the Source is always the highest point. ...read more.

Conclusion

This is due to rocks of large masses also being large in size. The significance of the mass of the sediment is that it can only be transported downstream if the velocity is large enough to carry it. For example, only a high velocity could carry heavy pieces of sediment. This means that large pieces will be found near to the Source and small ones close to the Mouth. I have made these predictions from theoretical background into the usual features of a river as so to make accurate predictions. ...read more.

  1. River channel processes.

    The foremost rock is a limestone called Portland stone. This is an extremely resistant rock and forms a barrier for marine erosion. Like all limestone it is heavily jointed and the cracks in the rocks are exploited by weathering and gradually these will be big enough so the sea can weather and erode the rock behind it, i.e.

  2. Study the downstream changes of Loughton Brook.

    A ranging pole and a tape measure are required. Water Width Water width was necessary for obtaining the channel width. A tape measure is used to measure the water from one side to the other starting at the place where the bank to water point ends. Wetted Perimeter The wetted perimeter is the distance that the water is in contact with.

    been recorded even if the river flow had actually been the same. The distance from the bank of the river where each twig was put in could also affect the speed at which it travelled as some parts of the river flow faster than others due to the helicoidal flow.

  1. Do the Characteristics of a river change downstream?

    There should be more precipitation in general. The average annual rainfall in the Wharfe catchment area varies from 1835mm on Fountains Fell to 590mm at Cawood. There are no prominent instances of land use either side of the stream although most of the land is used for either sheep and goat grazing or simply footpaths used by walkers and hikers.

    More invertebrates will live at the edge of the river because they have the adaptations to live there. This prediction proved to be true because there was a result of a total of ninety-six more invertebrates for all seven groups.

    Straightening rivers means rivers can flow with a higher velocity and so efficiently away from houses as it is not slowed by meanders. Planting more trees and plants in the flood plain can reduce the amount of water. The leaves intercept the rainfall delaying the run-off to the river that

  2. Investigate how the velocity of rivers changes.

    I also predict that the depth at the centre of the river will be deeper than the depth at the two banks. The velocity of the river will be slowest at the wetted perimeter where the river comes into contact with it's banks and bed.
