説明

Sedimentation is a big problem in the sense of sustainability of surface water resource, especially in North Africa under the Mediterranean climate system. The counter measure to that problem is simply dredging but it has not been carried out in North African countries due to the financial reason. In this study, the present condition of sedimentation on the reservoir in Tunisia is reported and the practical countermeasure to that problem is suggested with regard to the possibility of using sediment as soil amelioration for alkaline saline soil which is very serious in North Africa.First, the bathymetric survey was carried out in order to grasp the development of sedimentation. And then, the water quality parameters were observed for the discussion of mass transfer in the water body. Finally, humic substances which can play a role of soil amelioration for saline alkaline soil are confirmed in the sediment sample.
