英文摘要	The problem of water erosion is the result of the combined effect of rains and runoff water. This latter usually occurs as a result of poor drainage and soil compaction in the context of the semi-arid climate marked by short stormy rains. Broken aggregates washed fine elements, formation of a slaking crust, accumulation of excess water in puddles, and formation of runoff water with high turbidity, are the most frequently known processes used in the control of water erosion. Therefore, soil losses are produced at a rate that is accelerated with the current climate changes and the exacerbated pressure of man at the expense of the already scarce soil resources which are naturally restored at the rate of a few millimeters per year in ideal bioclimatic and human conditions. Land degradation and the environmental effects that could result from it remain among the main challenges for Assirian peasant society. The risk of erosion in the region of Assir finds its origins in its very jagged topography, sometimes unsuitable for farming with very difficult access and in the proliferation of city life. Indeed, the deterioration of the natural plant cover is only one witness among others of this degradation of soil resources and insidious erosion dynamic. Faced with this problem, an ancestral anti-erosion control strategy was introduced early on, based essentially on the agricultural terraces set up on the slopes, the corridors, and the intramontane basins, delimited by retaining walls and dry-stone cords. However, we must insist on the partial awareness of the scientific communities of the threatened situation of these ancestral works. The results of the modeling of soil loss through the RUSLE as a derivative model from the original equation (USLE) and the FAO formula have shown a significant specific loss of soil which is variable between 40 tons/ha/year (RUSLE) and 41.2 tons/ha/year (FAO). These results are obtained by modeling process without the appropriate adjustment by modifying certain input parameters and with no intervention on the models. As a result of the structural adjustment granted to the quantifying models (RUSLE and FAO), the soil loss was significantly decreased, especially for the FAO formula, and remained steady between 36.1 tons/ha/year (FAO) and 40 tons/ha/year for the RUSLE equation.
