Abstract
World War II UXO detection is a present day subject due to the large amounts of ammunition that is still buried in the subsurface. These may pose a threat during digging activities at larger depths. Removal is a four phase process, including historical research and geophysical detection onshore and offshore. A range of geophysical techniques, including their (dis)advantages, is described. The methods selected are based on historical information, soil type, potential disturbing objects and efficiency.
Geophysical UXO detection, geotechnics and infrastructure planning are interrelated. UXO detection activities can be reduced by geotechnical information. Infrastructure planning delays can be reduced by on time initiation of UXO detection and removal and careful planning. Planning takes into account in detail the infrastructural activities that will be carried out, its phasing and possibilities for intermediate reporting of geophysical research outcomes.
