Introduction
Geographically, Morocco is situated in North Africa precisely with the
African and the European plates which enforces a great richness, variety
and complexity of Moroccan geology seeing its different structural
domains.
The Middle Atlas region is characterized by its hugely diverse
landscapes. As a matter of fact, its geological wealth is a considerable
asset for the local development of the region. The quality of the
geological outcrops makes it easy to read the history of this part of
the Atlasic chain from the Paleozoic to the present day. The Middle
Atlas, which constitutes an intracontinental chain whose mountainous and
structural buildings are elongated essentially in the NE-SW direction,
this chain is longitudinally subdivided into two structural domains
separated by a major tectonic faults ” NMAF ”, which separates the
tabular Middle Atlas to the NW from the folded Middle Atlas to the SE.
The Paleozoic outcrops there in several buttonholes like (Bsabis, El
Menzel, Tazekka, Beni Mellala…).
The Sefrou watershed in its downstream
part, spreads over an area close to 405 km² with a perimeter of 127.42
km. The main watercourse originates from mountainous springs (Benima, J
el Abed, Jbel l’Abd, Chaabat-Mbarek …) and drains the Middle Atlas
tabular area through the city of Sefrou towards its connection with the
Oued Sebou which exists at the level of the Rif southern corridor
crossing different geographical areas, and different bioclimatic
environments.
Using a physical characterization method with a certain set of
parameters allows us to follow and better understand the hydrodynamic
behavior of the Watershed.
