Review: Saltwater intrusion in fractured crystalline bedrock

Abstract During the past few years, number of regional and national assessments groundwater quality in regard to saltwater intrusion coastal aquifers has increased steadily. However, most international literature on is focused plains with unconsolidated material. Case studies, modelling approaches parameter studies dealing those systems are abundant. While hydrogeology fractured rock been intensively studied both studies—mainly relation deep-laying crystalline bedrock as potential waste repositories—case shallow rocks still an exception. This review summarizes actual knowledge rock. In combination short overviews processes intrusion, flow genesis these systems, highlights importance fracture its specific characteristics. Fracture properties a direct consequence geological history well current situation area. A holistic assessment water areas hosting therefore requires different order investigate impact through system.
