Abstract The geomorphology of the Htab river watershed is mainly guided by the action of the
E-W Kasserine fault. This activity influenced the installed hydrographic system. To see the impact
of neotectonic on the Htab river watershed, four morphometric indices were applied: the
elongation ratio, the hypsometric curve, the hypsometric integral, and the asymmetry factor. The
processing and calculation of these indices were based on global DEMs (Digital Elevation
Models). The result obtained shows an important link between the activity of the Kasserine fault,
the geomorphological behavior of the Htab river watershed and the hydrographic network. Field
observations confirmed well these… More >
