Abstract

Filtering and storage of precipitation, runoff, and subsequent groundwater recharge is governed by the structure and properties of the shallow subsurface and the soils formed therein. Hence, detailed knowledge about the three-dimensional structure, thickness and composition of the shallow subsurface is essential to quantify these processes; special benefit can be derived in connection with the hydraulic and material-specific properties. Geobodies can be mapped by complementary, non-invasive, geophysical methods. Associated with lithofacies, geophysical and other properties these “geobodies” can be fingerprinted. A 3D model containing e.g. porosity, field capacity, permeability, grain size and soil chemistry can be build. Geoelectrical resistance tomography and three-dimensional (3D) ground-penetrating radar surveys have been carried out in the catchment of the “Seebach” (Forbach, Bunter, Black Forest, Southern Germany). A test field was established and investigated with respect to the sedimentological and pedological architecture of the shallow subsurface, going along with lithofacies mapping, granulometry, and permeability investigations. The synthesis of all data resulted in a three-dimensional quantitative subsurface model of the shallow subsurface architecture. Together with the associated hydrological characteristics, this can serve as input parameters for water budget and sorption models.
