High resolution 3D seismic survey off-shore the Netherlands

TNO has carried out a high resolution 3D seismic survey off-shore Rotterdam. The new deployment concept that was tested with this survey results in high-quality 3D images of the shallow subsurface at relatively low cost, particularly in comparison with conventional 3D seismic data acquisition. Initially, the pilot survey aims to demonstrate the...

Quantifying sediment dynamics within the Dutch Wadden Sea using bathymetric monitoring series

During the last millennium, human intervention has had an increasing impact on the bathymetry of the Wadden Sea. The significance of these human-induced changes for the decadal-scale development of the Wadden Sea in light of natural sediment dynamics is still unknown. We compared a series of 20 th-century bathymetric grids and the top of the...

Geophysical investigation of a dutch levee and canal using various seismic and GPR techniques

A geophysical survey has been carried out on the Juliana Canal and levee in the south of the Netherlands. For a stretch of about 35 km along this canal various construction works are planned, to deepen and widen the canal. The canal is in a geological setting such that leakage from the canal to the surrounding landscape during the construction...

The sand extraction potential of embedded land surface lowering in the Netherlands

In the Netherlands, mineral extraction by means of dredging or quarrying meets with considerable societal resistance. Land surface lowering prior to large land reconstruction projects may raise fewer objections. We have calculated the potential yields of sand and gravel from land surface lowering embedded in planned building and construction...
