The Chott el Djerid is an ephemeral salt playa situated in an arid zone closed basin which has a catchment area of 10500km2. The Chott el Djerid itself has a surface area of approximately 5360km2. The interpretation of climate change in this period and its relation to sediments, specifically lake shoreline deposits found within the Chott el Djerid basin, have become more controversial in recent times. Studies have shown that due to climate change, rainfall in the basin has been decreasing in recent years. The recorded presence of surface water on the Chott el Djerid can be related to rainfall events in the basin (click here for more information).
