Abstract
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 works is a significant risk. To be able to adapt the construction works to the specific circumstances on hand, a number of geophysical methods were selected to determine the required characterisation of the subsurface. From these techniques the sub bottom profiles and side scan sonar on the canal, the S-wave reflection and GPR measurement on the levee provided most useful information.
