Slope failure characterization: A joint multi-geophysical and geotechnical analysis, case study of Babor Mountains range, NE Algeria

Purpose. The research purpose is to apply an original combined approach the study of landslide occurrence in Tarzoust region, based on geophysical approaches. This extremely important because landslides damage roads and buildings many parts North Africa, especially city Tarzoust, NE Algeria. Significant slope failures have resulted serious disasters region. Methods. In this we use Vertical Electric Soundings (VES) Seismic Refraction Method (SRM) for underground exploration, as well Electrical Resistivity Tomography (ERT) support latter two methods. Findings. clayey nature terrain confirmed, very often covered by a mantle superficial colluvium formations. depth bedrock shear surface has been precisely determined. ERT reveals that already experienced instability past. Originality. originality combination data from various sources different approaches planning deployment land. Practical implications. Our proven geological geotechnical with deterministic methods can help engineers decision-makers land management. recommendations consist topographic, inclinometric piezometric monitoring slip development effectiveness reinforcement measures new housing, equipment programs regional planning.
