Santorini and the great ocean road Coastal Landforms Presentation By Krishaal And Sasha

Introduction

As you all know we went to the great ocean road on the 15th of march. We went there to study different coastlines and why they look like they do today. We went to three differe'nt coastlines; Bells beach, Point Roadkinght and Anglesea beach. In this presentation we will be focusing on Bells beach and its connection to Santorini, Greece.

bellS beach

Bells beach is a coastal land form located in Victoria. It is a renowned surfing beach and is known for the surfing competition known as the rip-curl pro.

It is located 100 km southwest of Melbourne and is near the town of torquay.

Features of Bells beach

Geographical features of the beach include:

◾️A big Headland that has been eroded and shows signs of present erosion

◾️ An escarpment that is close to the allocated parking spaces and has been eroded for some time

◾️A steep slope going from the bottom of the escarpment to the sea (caused by erosion)

◾️Very destructive waves (frequency 7 waves per minute)

Coastal management strategies

The government has been revegetating the area around bells beach in order to slow the force of destructive waves eroding the face of a cliff

Santorini

Santorini is a popular tourist destination and an island governed by greece.

It was built up in the year 1645 BC by volcanic eruptions and was eventually settled 1300 years later.

In 1957, there was only one more eruption from the volcano, this was the last recorded eruption and there have been no eruptions since.

The island is made up of limestone, black sand and white sand. The white sand occurs from the erosion and deposition of the limestone and the black sand occurs from the ash mixed with white sand, creating a mixture of white and black sand. There is also red sand from erosion of the red rocks that make up the island.

Santorini has been eroded for a long time, creating slopes from the rock face leading into the water. There are very small beaches compared to its land size but each one of the ten main beaches are spectacular. The most well known beach is the red beach.

The island is very mountainous, it is made almost entirley of hills with a volcano in the centre of the island.

There are many towns and villages in Santorini built all around the island, but the most well known is Fira, the town that stands on a cliff overlooks the coast.

Coastal management strategies:

There is not much coastal management as many villages are built directly onto the cliff face and not much is done to stop the erosion of the coast, even if there isn't much erosion happening.

The island of Santorini slants downhill from the high cliffs to the Aegean Sea. There is also a comparatively smaller island, Thirassia, that forms the boundary of Santorini lagoon. In the beginning, about two million years ago, Santorini used to be a small non-volcanic island. Mount Profitis Ilias, located to the southeastern part of Santorini, bears testimony to this fact as its non-volcanic limestone would suggest.
