Shift Performance

 

Lake Eyre is amazed by it’s mystery.  To be “disappeared” every three years, meanwhile, to be encountered  the flood every decade are its consistent style. For those visitors,the style of shift from full to “disappear” introduces completely different experiences every single year. What causes the shift? And how we can perform this shift through mapping? Firstly, the intuition reason of the shift is the changes in rainfall. And secondly, rom meteorology point of view, this ghosty behavior is mostly based on the shift between the effect of La Nina and El Nino which make the world extremely cold and warm. Obviously the shift between the two climate phenomenas create the performance of Lake Eyre. 

 

Mapping the relationship between the rainfall tendency and the perform of La Nina and El Nino help understanding the shift. The line technique of Maya Lin’s wire models( systematic landscapes and above and below) inspired the initial idea of represent the tendency; and the drawing precedent of James Corner contribute the technique of using density of lines to performance strong or weak. 

 

REWRITE

 

Lake Eyre is amazed by it’s mystery performance. As a seasonal lake, its area or boundary is influenced strongly by rainfall which is the mainly climate phenomenon of La Nina. So that it is not difficult to understand the fluctuation boundary of Lake Eyre. And the shape of every curves depends on the flow and erosion speed of every year. 

By mapping those boundaries, the data of rainfall is the basement to determine the approximate shape,  the channel form and the flow form the specific shape. 

The species invited in the lake is Australian Pelican. This kind of bird prefer large expanses of open water without too much aquatic vegetation, care less about the surrounding environment, and value the supply of sufficient fish. They usually stay at coast around Australia, but when lake eyre is flood, there will be almost no pelican around the coastal area. So this behaviour can be summarised the number of pelican depends on the size of water in Lake Eyre.

Water Defined


Lake Eyre has no fixed boundaries, it is a fluctuating entity. It goes through heavy floods every few years which witnesses the migration of various fauna and flora. This leads to certain water birds to migrate over large areas inland as well as humans temporarily migrating to the site via airplanes.

The migration of water from water to air creates a dependence onto which birds rely heavily. The hot air produced from atmospheric convection is an element that allows the bird to glide over large distances – something of paramount importance due to their heavy bodies. The birds travel an average of 100kms in 24hours – stopping along the way to fuel up (food, drink, breeding and habitat). These four elements are important to the survival of the Pelicans – the two forces that drive them are atmospherics convection and topography. The latter determines where and how the pelicans land to perform these tasks.

The vegetation around Lake Eyre is very minimal, therefore creating a barren, arid space that does not bring any rainfall. This leads to questioning: how can the rejuvenation of the space during drought season allow for pelicans to continually live around Lake Eyre? Our design proposal aims to keep the surface frequently wet; by creating forest-like spaces that attract more rain and therefore allow for the lake to be in abundance. This is a crucial element for the Australian Pelicans’ ecosystem to function.
