Does the size of beach material on a beach become smaller and more rounded as we get closer to the edge of the sea.

Introduction

Hypothesis Does the size of beach material on a beach become smaller and more rounded as we get closer to the sea? Introduction The project I have chosen to work at is "Font-y-gary Beach, Measuring the size of beach material." I choose this as I have always enjoyed the beach as a child and I have always prefered physical geography as it can show so much beauty. and going to beaches reminds me of beautiful beach I have seen on holidays. Out school did offer to other projects "Pontypridd, to investigate the CBD" "River Taff, to see where the river flows fastest" The reason of this study is to show weather the hypothesis (see hypothesis) is correct I went about this by measuring the material on three random transects of Font-y-gary beach. For a better understanding and wider range of results I decided to get results from another beach as the results from font-y-gary did not follow my hypothesis (I will state reasons in the conclusion) The beach I choose was Penarth which is located in the vale of Glamorgan we measured results from three random transects adjacent to the pier Here is a map of Penarth beach This is roughly where I started measuring pebbles (Here is an Ariel photography of the area) ...read more.

Conclusion

obviously suggesting that the ocean doesn't get that much time to erode the cliff face, as wave pounding can't happen very long as the tide will start going back out. It is apparent that the rocks at the cliff edge differ greatly in size to the pebbles at the shoreline which is visible as you get on the beach. It is also clear that the rocks decrease in size further down the beach. All this evidence therefore proves my hypothesis correct. This was more apparent at Penarth. There are a few things that could get in the way of my hypothesis thought Evaluation I believe all in all my experiment was successful even though my results from font-y-gary did not entirely prove my hypothesis correct but this is most properly due to the wave cut notch still I could of improved my experiment in a few ways. The simplest of ways is to do more transect. Another way could have been to do another beach even though I have done two. The more different ways I could of made the experiment better is I could of looked at tidal information so I could of measured more pebbles (when I arrived at font-y-gary the tide was in) as I was set to a time where I had to be home I couldn't wait for the tide to go out. ...read more.

    This measure meant that if further study were needed it would be easy to use the same area. In the sampling of sediment size it was extremely hard to perform truly randomly so we settled for the pseudo-random effort of simply picking a handful and a pre-designated site (in the middle of our transects).

    The diagram overleaf describes the two different waves and their effects. * Constructive waves build beaches. Each wave is low. As the wave breaks it carries material up the beach in its swash. The beach material will then be deposited as the backwash soaks into the sand or slowly drains away.
