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).

    This increases the transfer of water into the ocean store, causing sea level to rise worldwide. When the world was colder, during the Ice Age, large volumes of water were stored on the land as ice sheets and glaciers, possibly up to three times the current amount.

  2. 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.

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

    Because of the method of throwing a dog biscuit into the river, it was easy for it to get caught by rocks and foliage hanging over the stream, and easy for it to be caught by the current. If this test were to be done properly, a flow metre would

    All of my answers are the same as what the Bradshaw model of River characteristics states except for the load particle size and the channel bed roughness. Why? The water depth increases due to erosion. The occupied channel width, discharge and wetted perimeter increases due to erosion, tributaries joining, surface runoff into River, and through flow etc.

    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.

  2. Geography Coursework: Epping Forest

    I expect to find this because I expect the depth and width to increase with distance downstream and these results will be use in the calculation to find the cross-sectional area. Also this is because I expect the velocity to increase and so there will be more hydraulic power erosion, which will make the cannel larger.

    Site 2 is moderate with 40% but 5% (1sample) less is sub-angular. There is no rounded sample yet only 1 angular sample, which suggests the vast majority of bed load in Site 2 is sub-angular and moderate. This is in line with my prediction Site 3 is moderate with 40% but 5%(1 sample)

The environment agency is responsible for the all of the water present in the Wales and England. They have three main tasks, - control water resources - flood prevention - pollution control in rivers and other water bearing bodies e.g.
