Abstract:
Background and Objectives: Landslide is a geologic process in which gravity causes rock, soil, artificial fill or a combination of the three to move down a slope and can be activated by the slow weathering of rocks as well as soil erosion. This study aimed to investigate the lithological structures involved in the failure process, determine the landslide material and the influence of groundwater on the landslide occurrence. Materials and Methods: Integrated methods of 2D electrical resistivity and seismic refraction tomographies were carried out using resistivity meter and seismography with their accessories spaced at 2 m apart with a total length of 120 m and geo-referenced by differential GPS systems. Results: The interpreted results delineate three layer formations: First, second and third layer represent impermeable layer, permeable layer and saturated zones, respectively. Relatively low velocity, elastic and engineering parameters corresponds to the permeable materials in near surface with depth and thickness of about 4.75-11.50 and 4 - 4.75 m with higher porosity. Conclusion: These approach reveals that the complexity of the subsoil and sliding processes that affect the slopes movement and rock volume in the area. Hence, the results prove that the study area is liable to landslide and this can affects the environments, motorists and high speed heavy duty trucks movement through the area.
