The topic of the coastal and the effects of human intervention on its ecosystem is one of the most important tendencies worldwide in various international forums and environmental conferences.

The coastal zones have received much attention by various scientists, researchers as well as of activists, following the natural imbalance on both the continental and coastal zones alike, which has posed threats against its ecosystem.

The coastal of the region of Laayoune is a fragile intermediate space, owing, in the first place, to the combination of natural and human factors.

The coastal zone is a system based on exchanges between the continental and maritime sphere, what makes it sensitive and vulnerable due to any human irrational intervention.

We conducted this study in order to introduce this desert coastal center, represented by the coast of the region of Laayoune, of the coastal strip located between Assakia El Hamra valey and the center of Al-marsa.

The morphological evolution of the coastal in our space of study is attriburted to the human interventions, which head the main responsible factors for the imbalances in this space together with to the natural factors represented by hydrodynamics.

Interventions that did not take into account the natural peculiarities of the coastal system led to these aforementioned imbalances.In light of all these imbalances, we note the great shortcomings that affect coastal management in the region of Laayoune where all these interventions remain very weak and only rely on sectorial approximation, which is very far from the management integrated with the coastal zones, which will inevitably worsen the deterioration the coastal environment.

The problem to be addressed in this study is determined from the study of the dynamics controlling the geomorphological development of the coastal strip in the region of Laayoune.

We will address this problem by studying the natural dynamics associated with coastal hydrodynamics on the one hand, and then we will try to control human interventions that contribute to the development of the coastline
