It is well known that tectonic deformation along fault zones introduces heterogeneity and anisotropy into aquifers which can impact regional groundwater flow patterns. Therefore, fault zones have to be taken into consideration in hydrogeological studies, particularly where groundwater resource assessment and contamination are concerned. This is especially relevant with topical issues such as underground storage of nuclear waste and CO2 sequestration as faults can act as effective seals or conduits for fluid migration. However, the effective study of the impacts of fault zones on groundwater flow pathways will require an interdisciplinary effort of hydrogeologists and structural geologists. Nevertheless, researchers in these different fields both concerned with the hydrogeological characterization of faults employ very different techniques and approaches in the collection of field data to elucidate fault zone hydrogeology with usually little exchange and/or appreciation of eachothers results. This session will bring together research from both the structural geology and hydrogeology communities who have addressed the subject of faults and fluid flow, and combine evidence for the behaviour of shallow crustal faults. We welcome abstract submissions from all approaches to this question, including but not exclusive to: fault outcrop and microstructure studies, laboratory experiments, paleo-fluid flows analysis, boreholes and/or surface water data and groundwater flow modelling.
