To Test if Longshore Drift is Taking Place Along Deal Beach on the Day of Our Visit

For this aim, we measured the wave angle. To do this, I laid a

protractor on the floor, and watched for about 5 minutes in which

direction the waves were travelling. I would look down on the

protractor, and note down the angle of the waves. I then worked out

the average angle.

We had to do measure the wave angle because it would show us in which

direction the longshore drift (if any) was taking place, therefore

resulting back to the title of the aim.

On the day of the visit, the weather conditions were probably the

worst conditions of the week. There was rain early on in the morning

and when we arrived, so we had to wait in the minibus for the rain to

stop. It did, and so we could carry out our investigation. The

temperature was 59 º, so not very warm. The cloud cover was about 80%,

so not much sunshine at all.

To measure the wind speed, I used an instrument called Anemometer

(fig.3). I basically held this instrument up in the air, and the wind

would blow onto its fan, and it would measure the speed for me. To

measure the wind direction, I held my handkerchief up in the air, and

recorded using a compass, the direction the handkerchief was facing,

and went to the opposite of that because that would be the direction
