Analysis of recent deformation in the southern atlas of Tunisia using geomorphometry

Abstract

In this work, we propose to locate, characterize and quantify some topographic deformations linked to the seismotectonic context, and anthropogenic actions in the southern Atlas of Tunisia. The analysis of morphometric parameters (Residual Topography, Hypsometric Integral, Drainage anomalies, Maximum curvatures and Roughness) has revealed that three structures in the study area, J. Ben Younes, J. Bou Ramli and J. El Abiod, are distinguished by a specific morphometric and anomalous response which may reflect an important morphodynamic activity caused principally by the numerous reactivation of the Gafsa fault.
