Abstract

    The science of geomorphology is no longer a science based on description and classification of terrestrial shapes. Rather, it turned to the applied approach, so that its study became a pillar in surveying and evaluating land resources and employing their results in preparing development programs for the investment and maintenance of resources from environmental hazards and changes taking place in the landscape as well as building investment plans and managing its resources are in order to achieve the basic goals of the human beings which are safety, prosperity and stability.Geological surveys are a modern style used in applied geomorphology to identify the qualifications to develop plans for any area and also seek to uncover the spatial relationships between man and his environment through his response and challenge to them.The current studies of geomorphology focus on its applied aspects due to the current development in its contemporary techniques such as remote sensing and geographic information systems, which facilitated research procedures and detection of the components of the region easily and with high accuracy and with the lowest costs and effort and in a short time compared to the traditional methods, especially the applied ones.As sophisticated systems are available for creating maps and linking them to various databases of land resources, the importance of studying this area increases, as it is located in areas where dry and semi-arid climates prevail, as it becomes more vulnerable to environmental risks. The study of water erosion (Al-Zubaidi Basin) is important to identify the sensitivity of the surface for the environmental assessment of its reflection on land uses and to build a model for water erosion. For the qualitative evaluation of water erosion, PAP-CAR based on the basin area methodologyThe region is sensitive to geomorphological processes (mofotectonism, morphomimeclimatic and morphodynamics) due to tectonic activation, climatic extremism, dynamic energy and water flow due to the variation in the types of rocks and their characteristics, which led to a variation in their impact on the degree of the predation of the area and its response to the water erosion process and its reflection on land uses.
