Surface magnetic resonance (also known as surface NMR, proton magnetic resonance and magnetic resonance sounding) is a powerful ground-based geophysical method used to non-invasively detect, measure and image groundwater. ...

Clay exploration: The exploration of clay deposits is of great importance for the nonmetallic minerals industry mainly. Due to the higher conductivity of clay compared to coarser sediments such as sand and gravel geoelectric is an appropriate method to determine the expansion and thickness of clay ...

Karst structures: Solution processes are a common phenomenon in limestones and dolomites which can lead to karstification causing in many cases cavities. They can be air-filled or filled with fine-grained material, which decrease the soil stiffness and thus the load capacity. Exploratory drillings, which are generally used for soil investigations, provide only local information about the subsoil conditions and are not suitable to detect small-scaled structures in a geologically heterogeneous environment. ...

Strength characterization: Seismic methods are suitable to study the strength characteristics of dyke and dams. Seismic measurements are sensitive to density changes and compactness of soils. Therefore, areas with inadequate compactness of dykes can be detected. A correlation with SPT/CPT (Standard/Cone Penetration Testing) is often done because these methods also depend on the mechanical properties of the ...

Ship locks and lifts: A ship lock is an engineering structure which enables ships to overcome the level difference between two waterways. Water level is raised or lowered by filling or emptying the lock chambers. Filling and emptying a lock chamber is a central process of the ship lock which causes high cyclical loads on the underground. therefore, an a-priori estimate of the soil behaviour under loads is crucial for geotechnical engineers to select the best design parameters and to avoid undesired deformations on ...
