The Main Purpose The Site I Choose : The Glenelg Beach in adelaide The Reason I choose this site : Because I think this beach should be affected by coastal erosion, so I want to know what factors lead to coastal erosion.
The main purpose:The first is to use different software to understand the various factors of the site, such as cloud cpmpare, QGIS, etc., and then to analyze the number of drama, and write the conclusions.

BackGround Information- Glenelg Beach
Glenelg Beach is Adelaide's most of one popular city beach, offering a buzzing vibe and great atmosphere for all to enjoy. Renowned for its wide beach, stunning sunsets, rich heritage and bustling shops, sidewalk cafés and loads of entertainment. People can Take a dip, stroll the jetty, grab a bite to eat and watch the sunset over the ocean. The Glenelg Foreshore Playground and Moseley Square are hives of activity throughout the warmer months, offering a huge range of family-friendly entertainment and sporting activities.

BackGround - Costal Erosion
There are two main natural factors c a u s i n g c o a s t a l e ro s i o n : f i r s t , t h e enhancement of marine dynamic action, and the tidal current and wave generated in the process of sea water movement are the main driving forces causing coastal erosion. Inshore tidal current determines the offshore movement direction of coastal sediment and becomes one of the important causes of coastal erosion. The wave action is mainly manifested as incipient sediment and transport This caused by coastal erosion in melbourne sediment. Taking the Yellow River Delta as an example, the shoreline erosion in the Yellow River Delta is generally caused by the combined action of tide and wave, which enhances the coastal erosion. Second, global warming leads to the rise of sea level. Global warming causes the average sea level in many areas to rise slowly relative to the land. Because the beach profile will be gradually adjusted to adapt to the rising mean sea level, it will cause slow erosion of the shoreline. Sea level rise will not cause coastal erosion in a short time, but it will induce or accelerate coastal erosion This risk of adelaide in Lidar in a long time. The relative rise of sea level leads to the increase of nearshore water depth, which enhances the wave action reaching the shore and erodes the coast.

Site Analysis - Vegetation Vegetation
For the vegetation analysis of the site, I use the cloud compare computer software to draw the vegetation map around the coast. It can be seen that there are many vegetation in the city, especially around the buildings and roads. However, the vegetation in the beach area is almost zero, so it is a factor that will lead to serious coastal erosion.

ound-Costal-Rainfall The rainfall in Nan'ao is changing all the time, and the rainfall is relatively large, so there will be too much water on the road, which may lead to the occurrence of small floods. If you look at the ground and coastal map, according to the simulation data map of the software, it can be seen that the ground of the city is relatively stable and the distribution of the ground roads is relatively small, so the probability of water accumulation can be reduced, so as to reduce the occurrence of floods Water phenomenon, and the slope is relatively gentle, there is no pit phenomenon. However, relatively gentle erosion will become a disadvantage of coastal erosion, because every time the sea water washes away a small part of the sand, and the coastline is composed of sand, which is the most seriously eroded. Heavy rainfall also means that it takes away sand and makes sea level rise faster.

Site Analysis - Buliding Buliding
For the architectural analysis of the site, I use cloud Comparing the layout of buildings around the coast, we can see that there are fewer buildings near the coast, but there are many buildings far away from the coast, which is better, because more buildings mean more residents around, so there will be more human activities that can lead to serious coastal erosion, but we can see that there are not very many residents around, so it's better It is good for coastal erosion protection.

The Conclusion of the analysis
More Plants
Rock Dam
According to all the analysis, it is concluded that the lack of vegetation, geological materials a n d re g i o n a l ra i n fa l l a re t h e important factors leading to serious sea water erosion. Firstly, the lack of vegetation leads to the rapid geological loss, which makes the sea water erosion more and more serious. Therefore, i t i s n e c e s s a r y to p l a n t m o re vegetation to protect this beach. Secondly, the geological material is sand, and the sandy coastline is the most vulnerable of all materials, so we need to use rock and other materials to build a small dike to prevent serious coastal erosion. Thirdly, the solution to excessive rainfall is to build water outlets to prevent most of the rainfall from flowing to the coast, which can protect a certain amount of sand from being lost.
