Geomorphological Effects of Kathraba/Alaghwar Road by Using GIS

This study deals with the geomorphological effects of the Kathraba/Alaghwar road in AlKarak Governorate in southern Jordan, intending to clarify the geomorphological effects to which the study area is exposed, the quality of the engineering facilities and assessing the slippage of lands, the emphasis was placed on the Kathraba / Alaghwar road, due to its high economic importance and great terrain diversity, in terms of steepness and meandering, and this was done by studying geological and topographic maps, satellite images and climatic elements that were obtained, and using the GPS device, GIS software, Google Earth and through it, maps of the study area and terrain sections were extracted. The study concluded that the road construction affected the geomorphology of the area in terms of the spread of cutting and filling sites along the road and the risk of landslides, and it was found that the Kathrba / Alaghwar road falls within a very high slippage range.  The study recommended the use of specialists in the field of geology and geomorphology before starting the projects, increasing the number of hydraulic installations along the road, and establishing retaining walls in areas with high susceptibility to landslides.
