Description
Transport of solutes with groundwater flowing in fractures in connected flow paths the bedrock. These flowpaths meet, to a greater or lesser extent, so that water from different conductive fractures is mixed. Advection thereby leads to a situation where different water types replace each other and/or are mixed.
