This study was designed to prove that the coastal changes of the Gulf of Tunis are mainly driven by the changes of the hydrological regime of the Medjerda river due to dams. We sampled cores of sediments in the low valley just before the sea, and analyzed them. They show the dramatic reduction of sediment supply after 1981, date of construction of the largest dam of Sidi Salem, and the disappearance of sand in the fluvial sediments.

Exceptional floods in the context of heavy rains in central and eastern Europe, reaching flood danger quota on almost all of the tributaries in the middle sector of the Prut River. We found exceptional flooding along the main course of the Prut River and the occurrence of a unique backwater phenomenon called spider flow.

Short summary
The aim of this study consists in testing the effectiveness of satellite data in order to monitoring shoreline and sedimentary features changes, especially the rapidly changing of Gulf of Tunis coast. The study area is located in the Gulf of Tunis western bay (Southern Mediterranean Sea) which is characterized by sandy beaches of Ghar Melah and Raoued (Medjerda Delta area). The aerial photographs and satellite imageries were 15 used for mapping the evolution of shoreline. Diachronic data.
