Introduction

GCSE Geography Coursework (2003) Loughton Brook River Studies - Epping Forest Shah Azizur Rahman 11Q/3850 Ms Begum Stepney Green School (10548) Contents 1. Introduction 2. Method 3. Results 4. Description of results 5. Analysis of results 6. Conclusion 7. Limitations 8. Bibliography 9. Appendix GCSE Geography Coursework For my GCSE Geography Coursework I will be studying a river. My objective will be to see the river processes, natural features and the river landform through my investigation. The aim of my fieldwork is to investigate the characteristics of the Loughton Brook as the river goes downstream. We did this investigation on the 15th January in the winter season. The weather was very windy and it started to rain in the middle of the process of recording the results. The Loughton Brook, a small stream that flows through Epping Forest (Northeast of London) and the town of Loughton, Essex. The Loughton Brook is one of the many tributaries of the River Roding that eventually runs down to the River Thames. The Loughton Brook catchment (drainage basin) covers an area of 5.8km�. 60% is within Epping Forest. The remaining 40% is in Loughton. ...read more.

For this part of the investigation, we used a cork, stopwatch and a metre ruler. Velocity is speed going in a certain direction. Velocity is measured in seconds because we will use a stopwatch to record the time it takes for the cork to go from one end of the metre ruler to the other end. Results: Below is the table of results showing the velocity of the river at three specified sites (source, middle & mouth). Float Time (seconds) Source Middle Mouth Left 9 4 2.5 Middle 14 10 1 Right 8 15 0.9 Hypothesis 2: The width and the depth of the river channel increases as we go downstream (cross-sectional area). Method: In this part of the investigation, we measured the width and the depth of the river channel by using a measuring tape and metre ruler and using the metre ruler I saw how deep the river was. Using the measuring tape, I saw how long the water width was by measuring the width form one bank to the other. ...read more.

and the sphericity (high / low). We collected 11 pebbles from each site. Below is the Powers' Roundness Index and a map showing the site where we done this part of the investigation. River load is the load that the river carries from source to mouth. The River load was measured by using the Powers' Roundness Index and metre ruler. Results: Below is the table of results showing the water pebble analysis of the river at three specified sites (source, middle & mouth).

    and by slow groundwater flow underground, eventually returning to the ocean. In this way, the global water supply is recycled and conserved. By contrast, a river or drainage basin is an 'open' system - it forms part of this global hydrological cycle and has inputs and outputs - it is linked to other parts of the overall hydrological system.

  1. Study the downstream changes of Loughton Brook.

    The land provides the water source for the main river and its tributaries and its size depends on the river size. A river and its tributaries collect the rainwater in a drainage basin through soil and rock. Neighbouring drainage basins have a high ground separating them known as a watershed.

    Therefore, the cross-section of the river becomes larger, there will be less friction, and so the river should speed up. The data needed Relevance of the data How it will be collected Channel depth and width. This will help to tell whether the depth and width of the river increases as the stream order changes.

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

    - When looking at the cross-sectional area in the Bradshaw model, I can see that down stream the cross-sectional area increases. - To calculate the cross-sectional area of the stream, I needed to use the depth and width multiplied together (see fig.

    To measure the amount of water that comes into contact with the bed. Usually at a higher wetted perimeter there is more friction but also more velocity. * A subjective method of measuring because there may be several different interpretations to where the wetted perimeter is.

    There is no rounded sample and only one sub-rounded sample, which suggests the vast majority of bed load in Site 1 is angular and sub-angular. This is in line with my prediction. Site 2 is moderate with 40% but 5% (1sample)

  2. Does the river Alyn follow Bradshaw's model?

    It is difficult to see how depth would affect velocity as there are so many other factors to take into account. For example when the river got deeper the gradient may have been less, which would mean that there wasn't that much change in velocity.
