Contribution of bedrock structures to the bedrock surface topography and groundwater flow systems within deep glaciofluvial aquifers in Kurikka, Western Finland

One of the key challenges related to glaciofluvial aquifers is understanding how underlying bedrock structures and associated surface topography contributed deposition sediments generation groundwater flow pathways. In this study from Western Finland, we present a new digital elevation model Precambrian crystalline buried up 100 m beneath along Kurikka depression. We link structural anisotropy using additional data rock outcrops, boreholes gravity data. Brittle deformation zones are seen in bedrock-digital (DEM) as sharp breaks surface. These vertical fracture development interlinked elongate depressions delimit blocks with different elevations. A narrow, zigzagging trench, stepped floor, follows WNW-ESE NE-SW oriented forms major hydraulic connection between two parts aquifer. Furthermore, conductive conduits which connect shallow glacifluvial aquifer system deep bedrock. Understanding critical for successful modelling crystalline, fractured
