Evolution of the sandy coast of Gabes, S-E of Tunisia

Abstract

The Southern part of the Gulf of Gabes, SE of Tunisia, is a microtidal sandy coast. It is recently developing a series of sand spits. We seek to determine the evolution of the coast over the past decades and to establish the hydrodynamic conditions that led to this development. To do this, we relied on the diachronic study of the shoreline from aerial photographs from 1985 and 1997. Thus, the evolution of the coast is subject to continuous changes that reflect an active sediment dynamics. Keywords- Littoral drift, morphological evolution, sandy coast, sediment dynamics, spits.
