# GCSE Geography Coursework: Strand 3 - Data Presentation

Extracts from this document...

Introduction

This is the Data Presentation part of the coursework folder. The results are presented in the form of graphs and annotations are used to explain them. The results were derived from the geographical investigation conducted on the River Calder; June 10th 2008. (1) The relation between the Channel With and Depth: According to the Bradshaw Model, the Channel width and depth are expected to increase moving downstream from the source. Theory as to why this happens is explained in the Applied Understanding section of the coursework folder: points 1 and 2. I have used a scatter-diagram in-order to compare both continuous variables against two factors. ...read more.

Reasons as to why the Velocity and Discharge decrease greatly between site 1 and 2 are probed into in the Data Interpretation section of the coursework folder. (3) Bed-load roundness: According to the Bradshaw Model, the bed load roundness is expected to increase going downstream. Theory as to why this happens is explained in the Applied Understanding section of the coursework folder: point 7. I have used pie-charts in order to easily compare and contrast the proportion of different rock types at the five different sites. Site one (4-Km from source): Site two (5.2-Km from source): Site three (8.3-Km from source): Site four (11.4-Km from source): Site five (14.3-Km from source): (4) ...read more.

Conclusion

(5) Comparison of the Bed-load size at the five different sites: According to the Bradshaw Model, the Bed-load size is expected to decline going downstream. Theory as to why this happens is explained in the Applied Understanding section of the coursework folder: point 6. I have used a scatter-graph to clearly compare the b-axis size of different rocks to their site. A reason as to why the bed-load size generally increases is explained in the Applied Understand. Reasons as to why the rocks at site 2 fluctuate greatly, some surpassing site 1's, is probed into in the Data Interpretation section of the coursework folder. ?? ?? ?? ??

Channel roughness - the rougher the channel the slower the water flows i.e. if there's big boulders in the river, the water will have to go round them, slowing the flow. If however, it was a smooth channel i.e. no boulders or obstructions, the river will flow quite faster.

Much of the sand in Walton is being moved away due to longshore drift. .When the tides hit the cliffs, water forces its way into the cracks of the rock, (Hydraulic action), causing big damage over time. .When acid levels rise in the sea, cliffs can erode because of this acidity, (Corrosion)
