Abstract
 This paper introduces new restoration techniques for applying the world national heritage site Ichkeul in Tunisia, which are cost-effective and have low-environmental impacts. This study were explores two different laboratory tests to introduce of the natural sediments which collected in the Ishkeul lake. The main outcomes of this study as follows: 1) Microbial induced carbonate precipitation can improve the physical properties of natural sediments that collected in Ichkeul lake, 2) Precipitated calcite layer can covered the sediments surface and reduction of the re-suspended effect, 3) Microbial induced carbonate precipitation clay can still survive the benthos.
