Extracts from this document...

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).

  1. Hydrology and Fluvial geomorphology. (Q&A)

    An ox-bow lake is a meander bend that has been cut off from the main river by erosion and deposition. As the meander erodes on the outside of the bend, the neck of the meander will eventually get narrower. It only takes a period of heavy rainfall for there to be more water than usual in the river.

    bedload, the load particle size increases as you go downstream, but the Bradshaw model of River characteristics states that the load particle size should decrease as you go downstream. This will be evaluated late. My main findings. My results show: Fig.

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

    Is there a pattern in the data of the efficiency and cross sectional-area? - In the Bradshaw Model, both cross-sectional area and efficiency increase down stream. - An immediate pattern is recognizable after looking at the tables calculating the cross-sectional area and hydraulic radius as both tables result's increase.

    This data proved my hypothesis correct. With the factor channel shape you can see at site 1 how highly undulated the channel shape is. This is due to huge boulders from weathering processes from the edges falling into the river, building up the riverbed into the form of what is in the present day.

  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. Does the river Alyn follow Bradshaw's model?

    For example river width may increase which should lead to an increase in velocity, but if simultaneously depth and gradient were to reduce then the increase in river width would appear to have no effect on velocity. Consequently there wasn't a strong correlation between velocity and the other variables.

    In this method, a river with no tributary is called a 1st order stream. So two 1st orders joining up makes a 2nd order stream. A 1st and a 2nd order stream joining up will still make a 1st order stream.
