On the side of the valley the bank is quite swampy and sandy. On the other side, the mountain side, there is once again mainly deciduous forest. The banks are fairly broad and do not drastically increase in height as in location 2. The river at location three is the widest. Beyond bankful there are mainly gravel and pebbles, but until then the banks consist of mud and sand. Figure 6.3 - In the foreground it is possible to see big boulders and the background shows the pebbly beach.

  1. Study the downstream changes of Loughton Brook.

    All sites were crammed into 800-900m of river because below that point flood management schemes occurred. Since I only measured a few sites of this river I might not have gotten a clear indication of Loughton Brook's downstream changes. However, had I measured the entire rivers length I would have had more accurateness in my survey.

  2. 'To what extent does the River Lyn conform to the Bradshaw model of River ...

    except for the load quantity and channel bed roughness of the River Lyn. It was not possible to obtain data, because we did not have sufficient equipment or time to do this. The title has been broken down into key questions to help me answer it.

  1. Study the river Cray and see whether the river actually follows a natural path ...

    This cycle shows the rivers journey from source to mouth and shows most of the key processes that happen throughout its journey. However the model of a river on the first page gives a better visual aid as to how a river looks from its beginning to end.

  2. I am going to study the characteristics of rivers and how they change as ...

    and the highest banks. The right side of the bank is shorter (154cm) than the left side (176cm). The water width is also higher (135cm) than the rest of the stream orders. The channel width is the highest (387cm) because of the erosion of the banks.

  1. How does the Efficiency and Cross-Sectional Area of a River Change Down Stream?

    To work out the cross-sectional area I needed to times the depth by the width. For site one, the equation can be seen below: dw = csa 8.1 x 1.9 = csa Looking at the Bradshaw model, the cross-sectional area of the stream increases the closer it gets to the mouth.

  2. River channel processes.

    Durdle door is an impressive arch which has been formed by the sea finally cutting through the rock and forming a hole in the rock. After time the arch will get weathered and finally collapse. It could then leave a stack.

  1. This project will study about the way the river Conwy in north Wales changes ...

    BED LOAD SIZE: I expect the size of the bed load will be decreases as it travels downstream because the stones will eroded by solution, saltation attrition, and abrasion. CROSS SECTIONAL AREA: I expect the cross sectional area of the river to be increased as it travels downstream because there
