Gully erosion in semiarid regions: The 2nd International Geography Symposium GEOMED2010

Gully erosion, as one of the most critical and destructive water-made types of erosion, results in displacement of huge mass of soil, sedimentation, and degradation. By considering importance of the subjects and with regard to the fact that studied region contains large and extensive gully which introduces potential hazard for croplands and habitats, and also make it difficult to pass through them, it is required to perform all possible actions which leads to bring an end to development and expansion of gullies. Therefore the choice of gully erosion in semiarid regions topic proposes a necessary research on the subject. Considering challenges faced in semiarid region, the study tries to evaluate all effective elements on formation and development of gullies or erosion-sensitive area by performing applied and scientific studies. In order to achieve pre–determined goals, and providing great assistance for appropriate planning and management, the research applied objectives such as: To understand gully erosion processes, To understand Impacts of gully erosion, and To manage the gully erosion in semiarid regions. In this study, I will use GIS and Ilwis for preparing the maps, and Excel for preparing the graphs
