3D-shallow subsurface characterisation, modelling and visualisation for the construction of a Radial Collector Well at Macharen, southern Netherlands

Detailed characterisation and 3D-modelling of the shallow subsurface was carried out for the construction of a Radial Collector Well (RCW) at the drinking water pumping station of Brabant Water at Macharen (near ‘s Hertogenbosch, province of Noord-Brabant, southern Netherlands). The objective was to assess the lithological and hydraulic properties of the uppermost 30 m of the subsoil in order to find the optimal depth and orientation of the 4 horizontal collector arms of the RCW.
