Like other cities in the region of Fez-Meknes, Taza undergoes the phenomena of erosion of soils facing the builder in general and the town planner in particular. This type of aggression of the land is sometimes amplified by the swelling-withdrawal of soils. In effect the marl clay layers are considered as unstable soils because of their volumetric changes depending on the duration and intensity of extreme climate changes (weather, droughts, ventilation.). This phenomenon, which is part directly or indirectly so-called natural disasters, can lead to significant costly damage and particularly intense (soil erosion, landslides, obstruction of the course of the water, hydraulic works and sanitation networks, cracks of the constructions and their annexes', deformations of pavements, etc.). The knowledge and mastery of this phenomenon are essential to prevent, limit or remedy the consequences and damage related to their impacts. We focus as well our contribution on the geotechnical characteristics of the soils of the city of Taza with highlighting of the hazards in susceptibility to erosion of soils in particular through their potential of swelling-removing and this for the benefit geotechnical zoning of Taza.
