Assessment of relative tectonic activity using morphotectonic analysis in the Central High Atlas, Demnate Region, Morocco

This study focuses on the morphotectonics of Central High Atlas in Morocco through analysis morphotectonic indices recorded by topography, drainage networks, and longitudinal stream profiles. The methods used this work were length-gradient index (SLI), normalized steepness index, area-altitude relations (hypsometric curves), mountain front sinuosity, basin shape ratio, asymmetry factor. aim is to identify role recent tectonic activity resulting uplift chain general particular. main rivers area using linear geomorphic proxies revealed presence several knickpoints (about 28) most likely related activity; further, spatial distribution SLI values reveals many anomalous zones, which are distinguished elevated that perfectly aligned with major faults. calculation areal supports confirms these findings. results obtained show has been influenced tectonics, some areas have experienced a due probably reactivation thrust oblique-slip faults, then high topography can be explained compressive component transpressional geodynamic regime suggested Plio-Quaternary period.
