حركة المواد الأرنية و مخاطرها الجيومورفولوجية على أسطح المنحدرات الجبلية المطلة على طريق نقيل سمارة إب-اليمن

Abstract EN

This study examines the geo-morphological risks to which the Smara Naqeel road is exposed to, resulting from the movement of ground materials that form the surfaces of the mountain slopes overlooking and parallel to the road, and highlighting the most important natural factors that increase the activity of the movement of materials contributing to the occurrence of landslides, and thus determine the spatial distribution of the types of landslides (landslips) on the side overlooking the road.

through a field trip to the study area and by using the descriptive and analytical approach, a set of results were reached : the most geo-morphological risks of slips and landslides are mostly concentrated on the right side of the Naqil Samara road, and most of their spatial distribution is concentrated in the third central region, and the fourth northern region of the road, with a percentage (41.51%) and (50%), respectively, of the total number of observed cases in the region of (212) cases.

it is one of the most dangerous areas for landslips and landslides, due to the steep slope of the slopes, the proximity of the distance from the road, and the huge collapsed and potentially collapsing rock masses.

further, the most active movement of ground materials include the phenomenon of falling reaching (37.7%) of the total number of landslides, followed by sliding which include (plane, rotational, wedge slip) by (30.7%) in addition to crawling by (18.4%).
