Geological Study:
The geological nature of the terrain is one of the main factors contributing to landslides and various geotechnical problems and risks, as well as are water and slopes (rockfalls, flooding, seismicity, clay shrinkage and swelling, rising water tables, excessive settlement of compressible soil, etc.), which could destabilize the structure and its environment. To this end, it is essential to understand the geological nature of the region and its surroundings. The first step is to identify the soil by visual observation of the different layers, confirmed by examining geological maps and conducting a geological survey.
Hydrogeological study:
Water is the main factor in geotechnical risks. Therefore, the objective of the hydrogeological study is to identify the various water resources existing in the study area and its surroundings: groundwater, wadis, etc.
Piezometric measurements and water sampling will be carried out in order to measure the groundwater level and determine the chemical characteristics of the water. Lugeon and Lefranc permeability tests will also be performed.
The hydrogeological study also makes it possible to define the prevailing climatic conditions in the study area.
