This extended abstract briefly discusses some initial results from an ongoing collaborative research project between University College Dublin, Queen’s University Belfast and the British Geological Survey as well as industry partners Aecom, Canal & River Trust and the Environment Agency. The project, funded by the Natural Environment Research Council (NERC), is investigating the application of geophysical techniques for improving flood defence management at a number of sites in Northern Ireland and England. The expanded abstract focuses on initial results from one case study, where a number of geophysical methods have been used to forensically examine the cause of a reservoir embankment leak. Although geophysical surveys can provide useful information in isolation, when used in conjunction, or calibrated, with relevant geotechnical properties, they can be valuable tools for assessing geotechnical infrastructure condition and for identifying possible seepage pathways through reservoir embankment dams.
