VISUALISATION: DIFFERENT POSITIONS OF EMOTIONS

Rawai Beach, Phuket, Thailand

Phuket, Thailand, is located in the southeast of the Andaman Sea in the Indian Ocean. The island's pristine environment has made it a famous holiday island. However, the island is constantly exposed to natural disasters, such as tsunamis and typhoons. This is especially true in the south, where the urban areas are close to the coast. Flooding can be devastating for residents and visitors alike. The government has struggled for a long time to come up with an effective response to such problems. Too much security can lead to a loss of tourism on the coast. How to renovate the coast without affecting revenue has become a difficult problem. At the same time, due to the global impact of the epidemic, tourists leave a lot of discarded masks on the beaches. Such litter will undoubtedly damage the beach and affect the experience of other visitors.

Mangroves are one of the most productive marine ecosystems in the tropical and subtropical coastal zone, and play a vital role in purifying seawater, preventing wind and waves, maintaining biodiversity, and storing carbon. Unfortunately, the destruction of mangroves by humans has led to a dramatic decline in their numbers.

The rational use of mangroves and mask waste to transform the site can be used to protect the coast from flooding and at the same time beautify the coast and turn it into a new tourist attraction for visitors to enjoy. therefore travelled to Phuket in June 2022 and carried out a site visit to design the project.

Background: Attack Of Tsunami

Phuket, located in the southeastern part of the Andaman Sea in the Indian Ocean. The island's pristine surroundings make it a famous holiday island. The island is however subject to natural disasters such as tsunamis as well as typhoons all year round. Especially in the south, where the urban areas lie against the coast. A flood attack would be devastating for residents and visitors alike.

Mangroves, as an ecological complex of land to sea overlap, are an important element against floods, typhoons and pollution. Unfortunately, the destruction of mangroves by humans has caused their numbers to plummet.

Strategy: Plant & Landfrom

Proper use of the terrain and mangroves can be effective against tsunami attacks. Shaping the terrain to take advantage of the different depths of the sea can be used to farm mangroves while resisting tsunamis. Different types of mangroves can also be selected to achieve different functions.

Tsunami blocking method

2nd Defence Normal water level (seawater flooding) Lowering of the water level after low tide Save a small amount of seawater when dry Normally fully submerged in seawater The sea will shallowly submerge the piles Seawater is absorbed by sand in dry periods
