  15. Identification of Effective Transboundary Aquifer Areas (ETAAs)

  16. OBJECTIVES

  17. - The ETAA approach offers an alternative way to assess priority areas within the natural boundaries of each HGU.

  18. - The ETAA approach offers an alternative way to assess priority areas within the natural boundaries of each HGU. - A more refined, practical and effective aquifer boundary can be delineated.

  19. - The ETAA approach offers an alternative way to assess priority areas within the natural boundaries of each HGU. - A more refined, practical and effective aquifer boundary can be delineated. - A more comprehensive and local approach for governance and management options in a more feasible way.

  20. - The ETAA approach offers an alternative way to assess priority areas within the natural boundaries of each HGU. - A more refined, practical and effective aquifer boundary can be delineated. - A more comprehensive and local approach for governance and management options in a more feasible way. - Applicable not just at the binational level but also at the domestic level.
