Groundwater Resources Assessment

1.Aims of the groundwater resources assessment

  • Develop an initial hydrogeological conceptual model for each catchment.
  • Using surface water catchments to access groundwater resources as internationally recognised management unit and have calibration point for all of the water in catchment.
  • Provide a basis for prioritising further investigation into groundwater resources in the catchment accross the east of Ireland.
  • Identify existing information which is not available for these series of reports which would be useful for further analysis.
  • Identify information gaps e.g. yields in aquifer propoerties which could be addressed by the GSI's Groundwater section by carrying out fieldwork.


  • Examine all relevant and available regional scale mapping and data to develop a conceptual understanding of the groundwater resources within the catchment.
  • This uses surface water catchments (the internationally recognised management unit for water resources, as they have a calibration point for all of the water in the catchment) to assess groundwater resrouces.
  • Use the conceptual understanding to divide the catchment into different hydrogeological zones.
  • Use results of assessment to prioritise areas for further investigations into the development of future groundwater resources and identify potential constraints.
