The institution of IAH regional groups is envisaged and encouraged. In fact, research on coastal aquifers dynamic is carried out in all continents and it would be very useful and convenient to favour mutual exchange of information and publicize it.

Cross-coordination with other commissions will be developed by exchanging information by e-mail contacts, meetings at workshops and conferences, cooperating in specific programmes, and  preparing publications

We would like to organize the information collected with the questionnaire in a data base, linked to Google Map. The development of a data base on all main world coastal aquifers affected by salt water intrusion is in progress.

Given the difficulty of gathering a representative number of commission members on the occasion of IAH meetings, an effort will be made to organize regular conferences via internet with different regional groups so as to define local problems. National chapters will be invited to propose their representatives in the commission.
