Coastal Landforms By Caroline.tomasic 8d


During the year eight's visit to Bells Beach, Anglesea and Point Roadknight we examined types of coastal landforms and how they were formed, management strategies that were used and we measured longshore drift.

The first beach we went to was Bells Beach. It had a large slope and a cliff which lead to the beach. There was a major revegetation project that covered the headland and lots of fences and stairs which protected the beach. The beach was quite wide and below the cliff there signs of erosion.

The second beach we went to was Anglesea. Anglesea had a wide beach, a revegetation project and a cliff. The beach was connected to a pond/ sewage water.

The third beach we went to was Point Roadknight. On one side it had a wide beach and the other side was narrow. There was also a cliff, a boat dock that acted like a groyn and some vegetation. In the distance there was also a few stacks that had mostly crumbled away by erosion.

Bells Beach

At Bells Beach the waves were approximately 1.4metres high and the frequency was 11 waves per minute. The waves were destructive and caused erosion.

Bells Beach had a long and wide headland that had a cliff face. The headland was almost entirely covered by a revegetation project which prevented sand from being blown inland. The beach was narrow and long. There was a steep cliff, that had been eroded away by destructive waves, and the erosion had left rocks below the cliff.


At Anglesea the waves were approximately 1 metre in height and the frequency was 8 waves per minute. The waves were constructive. The beach was wide and didn't go all the way around the headland. The headland had some vegetation but there was some sand dunes covering the headland, caused by deposition. The beach had a cliff which was caused by erosion and destructive waves.

Port Roadknight

The waves at Point Roadknight blew south-west and the average movement per minute was 11 metres. The waves on one side of the groyn were destructive and on the other side they were constructive. The beach was wide on the right side and narrow on the left side. This was caused by the boat ramp that prevented longshore drift and acted like a Groyn, which is an example of hard engineering. The boat ramp (groyn) protected one side of the beach but because longshore drift was prevented the waves weren't depositing sand on the other side of the boat ramp instead, eroding away the headland. There was a cliff which had been eroded by destructive waves. There was very little vegetation which meant sand could be pushed further into the headland to become sand dunes. On the right side of the beach there was also headland that had been eroded into a cliff by destructive waves. In the distance, stacks had also been formed in the sea.

Coastal Management

Along the coast the local councils had management strategies to preserve the coast. The council had put in fences, plants, rock/ gravel paths, revegetation projects, signs, seats, car parks, bins, toilets and stairs, along the coast. The fences stopped people from going near unstable areas like a cliff, which could crumble and fall any moment. Rock and gravel paths stopped people from walking on sand and their feet from pushing the sand further inland. Revegetation projects prevented sand dunes by stopping and holding sand, in the plants and vegetation, so they can't be blown and swept away further inland. Bins help stop people from throwing rubbish into the sea/beach and polluting it. There were signs that told people where, on a beach, they can't go and where the headland is fragile for people to stand. Car parks were built so that people don't have to drive and park on the beach, taking and depositing sand inland.

Revegetation projects are effective and work well because they prevent sand from coming inland and becoming sand dunes. Bells Beach had the best revegetation project because it covered almost the entire headland and there were no sand dunes. The fences at Point Roadknight were not very big or strong and people could easily walk over them and go to the fragile cliff that was being eroded. The cliff could easily crumble if someone went near it and the fences did not stop people from going near the cliff. The fences at Bells Beach were the strongest/ tallest and most effective because it blocked people from entering the headland/ cliff/ re-vegetation project. The car parks at Anglesea were the newest, biggest and most appealing amd becasue of them there were no cars on the beach, moving sand inland. The car parks prevented sand deposition and were very effective.

Fieldwork Evaluation

The frequency of waves and the height of waves data collection worked well because we could compare the measurements and see which beach had taller and more frequent waves. Drawing sketches the beach worked well because it meant we could remember the surroundings in more detail.
