Erosion
Erosion is the geological process in which Earth's surface is worn down from constant exposure to forces like water, wind, glaciers and waves. The rock and soil broken down in this process is transported and deposited in other locations.
Erosion is constantly reshaping the land around us, but this development takes a long time. Although this is a natural process, it has become an issue and is one of the main threats to the beach's conservation. Lady Robinson Beach has been significantly impacted by erosion due to the NSW State Government's dredging and development of Botany Bay. Due to this, deserted areas of the beach are closed by the council.

Deposition
Deposition is the process where eroded soil and sediments are transported by wind and water from one place to another and then added to an existing land form or land mass. The process of deposition is linked to how much energy a river has which is determined by how much water there is in the river channel and how fast it is flowing.
Deposition is occurring at Lady Robinson Beach where sand that has been eroded and transported is deposited on the beach by constructive waves. The processes of deposition produce a wide range of landforms.

Sand Transportation
Sand transportation refers to the transportation of eroded debris, which can be caused by rivers, glaciers, wind or ocean currents and tides.
At Lady Robinson Beach, transportation occurs when eroded rock, soil and sand from the shore is collected by the water and moved down the beach due to the wave direction of the bay. This movement of material parallel to the shore is called longshore drift and is a major factor in the changing shape of the shoreline over time.
