The study of landslides in the Inaouene watershed (northeastern Morocco) provides information on the relationships between landslides and morpho-structural analysis. Landslides affect part of the slopes and slopes of the valley. The configuration of this relationship is controlled by the combination of several predisposing factors. Two localities were studied, located in similar morpho-structural contexts, but characterized by a different lithology. The first determining factor was lithology, in particular the dominance of friable geological formations, especially marls in the locality of Chebabate and limestone soft formations in the locality of Tahla. The second factor was the tectonics, which is well individualized in the limestone of Tahla; in spite of friable lithology of the marls of Chebabate, one manages to disturb traces of the tectonics notably with the level of intercalation of the sandstone benches. Another factor that controls the dissection and the evolution of the landslides is the precipitation by the effect of abundance of the water of impregnation in the formations. The fieldwork is devoted to the measurement of the different faults encountered in the two localities to make the stereographic projection in order to elaborate canvas. The principal objective of this study is to find the relation between the evolution of the risks of erosion and landslide as well as the various factors, who control their spatiotemporal evolution. The results obtained will help managers and decision-makers in the development of watersheds in order to take the necessary steps to reduce the negative impact of this natural hazard on the environment, the population and their property.

滑坡与形态结构分析之间的关系：以摩洛哥东北部为例

对Inaouene流域（摩洛哥东北部）的滑坡研究提供了有关滑坡与形态构造分析之间关系的信息。滑坡影响山谷的部分山坡和山坡。此关系的配置由多个易患因素的组合控制。研究了两个地点，它们位于相似的形态结构环境中，但具有不同的岩性特征。第一个决定性因素是岩性，尤其是易碎的地质构造的优势，尤其是切巴贝特（Chebabate）地区的泥灰岩和塔赫拉（Tahla）地区的石灰岩软岩层。第二个因素是构造，在塔赫拉的石灰岩中很好地个体化了。尽管切巴巴特（Chebabate）沼泽的岩性很差，一个人设法干扰构造的痕迹，尤其是在砂岩台阶的夹层水平上。控制滑坡的解剖和演变的另一个因素是由于地层中大量浸水的影响而导致的降水。实地调查致力于测量两个地区遇到的不同断层，以进行立体投影，从而制作出精美的画布。这项研究的主要目的是发现侵蚀和滑坡风险的演变与控制其时空演变的各种因素之间的关系。获得的结果将有助于管理人员和决策者开发集水区，以便采取必要步骤减少这种自然灾害对环境的不利影响，
