Methodological principle

Ground-penetrating radar is a technique that uses high-frequency electromagnetic waves to acquire information on subsurface composition. The electromagnetic pulse is emitted from a transmitter antenna and propagates through the subsurface at a velocity determined by the dielectric properties of the subsurface materials. The pulse is reflected by inhomogeneities and layer boundaries and is received by a second antenna after a measured travel time (Schrott and Sass, 2008, Geomorphology).

Processed refraction seismic profile Methodological principle

The principle of seismic refraction is based on elastic waves travelling through different subsurface materials, such as sand, gravel, and bedrock, at different velocities. The denser the material, the faster the waves travel. On the basis of measured apparent velocities conclusions about subsurface structures can be drawn (Schrott and Sass, 2008, Geomorphology).
