A. Purpose of investigation
The key question I’ve been set to answer is:
What factors affect the gradient of the beach?
I have broken the question down into a set of mini hypotheses which I’ll try to answer. This should help me to focus on certain techniques and help me to draw conclusions on the evidence I have collected.
1. The larger pebbles tend to build up making the slope bumpy(less steep) however smaller ones will spread out and even out more making the slope smoother, steeper.
2. The wind is stronger in some parts of porlock bay than others, making waves stronger and more powerful. I think wind is the most important factor.
3. I think the steepest beach will be Hurlstone because it’s the end of the beach where pebbles will be at their smallest and roundest due to erosion.
4. I think the gentlest beach will be gore point because it’s at the beginning of the beach where the pebbles will be at their largest and more angular.
The study took place at Porlock bay in Somerset, Southwest England (see maps on next page). Porlock bay is a coastal area that’s sited near Devon and the Bristol Channel. The study took place at three coastal sites which were Gore Point, Porlock Weir, and Hurlstone. This area is the world’s 2nd largest tidal wave range place so it was a good place to study as it has strong tidal waves. It also
