| Content Summary | The geological conceptual model is a key source of uncertainty in predictions of groundwater flow. Groundwater modellers typically have a prior knowledge about the reservoir data based on existing geologic maps, outcrops, lithological logs, pumping data and hydrogeological properties of the groundwater system. Uncertainties in the simulation results are largely dominated by uncertainties arising from the definition of the boundary conditions. Groundwater management in karst is often more difficult, because the geologic heterogeneity controlling the groundwater flow is often insufficiently mapped. The Alpine basement of Crete is composed of a number of fault bounded tectonic units with different lithologies, paleogeographical origin and metamorphic grade. Among others, a group of metamorphic rocks, composed mainly of phyllite and quartzite, has been described through time with variable names. This Group lies between Tripolitza nappe and Crete-Mani Unit/Plattenkalk Group or/and the Trypali Unit, and its maximum surface extension is located in W. Crete. Trypali Unit consists of carbonate formations with intensive karstification and forms a separate hydrogeological entity in the area. The stratigraphic position of Phyllite/Quartzite Series in western Crete (normal or overturned), as well as the extension of the Trypali Unit, still remains a matter of debate. In order to answer the main questions related to the hydrogeology of the region, the relation between the crystalline carbonate formations (Trypali Unit) and the metaclastic formations (Phyllite/Quartzite Series) was investigated and a new lithological map of an area (of about 80 km2) was created. This map can be used to clarify the hydrogeological regime in the area and to evaluate the available groundwater resources. | en |
