Accumulated Deposition – Jing & Karol

Lake Eyre is the biggest salt lake in Australia, it covers approximately one sixth of the country. It goes through heavy floods every few years which creates a booming, resourceful landscape that attracts Australian Pelicans from the coast of Australia. This project aims to create a nesting zone for this specie, in order to enable their migration over flood seasons. Within the lake a series of islands can be found, they are either taken over by the pelicans or covered by the floods. One of the largest islands was identified as the potential site. The analysis of the tendencies of this landscape over time allowed for an understanding that the floods may occur more frequently and therefore more pelicans would inhabit the space. This design is not invasive in the sense that the island creation occurs in a natural manner. The strategy involves utilizing under water plants as a way of slowing water down, and consequently allowing for sediment build up to occur where the island currently exists. Posidonia Australia is a species of seagrass that occurs in the southern water of Australia. It is found at depths from 1 metre to 15 metres. Subsurface rhizomes and roots provide stability in the sands it occupies, erect rhizomes and leaves reduce the accumulation of silt. Therefore, using this planting scheme will allow for the natural growth of the island and provide larger nesting areas for the Australian Pelican.
