摘 要：New Sohag City has an area of approximately 1300 acres (546 hectares) and is located within Sohag Governorate limits, about 18 km away from old Sohag City. It is established to reduce the population within the old Sohag city and to create better economic conditions in a new appropriate living environment. The main target of this study is to apply the relevant surface geophysical methods to image the shallow subsurface setting, to define the shallow lithological layers and to locate any geological structures that may be cause cracks in buildings, and any unstable materials, which may decrease the bearing capacity or human activities, hence increasing hazards in the study area. This study embraces, Electrical Resistivity Tomography (ERT), Shallow Seismic Refraction (SSR), and Ground Penetrating Radar surveys (GPR). The integrated interpretation of all techniques classified the subsurface layers into two layers. A strong reflector separating the upper gravel and calcareous sandy layer from the lower clayey layer. They gave also interesting information about the geotechnical competent of the ground and some structural features in the study area.
