Role of ICGW


The International Commission on Groundwater (ICGW) is responsible for the advancement of the science of groundwater hydrology, including the scientific basis for groundwater resource assessment and groundwater management.  It is also responsible for helping to bridge the gap between science and practice.  A primary objective is to give greater exposure to valuable new technologies and methodologies that are useful in groundwater resource and water quality studies.  This is accomplished through organized technology transfer activities and publications.  The Commission discharges its responsibilities in three ways.  First, it organizes and sponsors significant international and regional symposia.  Second, it collaborates with other IAHS Commissions and with other scientific organizations, including the American Geophysical Union (AGU), the International Association of Hydrogeologists (IAH), and the International Ground Water Modelling Center (IGWMC).  Third, it organizes working groups to develop reports which focus on new and important aspects of hydrogeology.  These activities are frequently coordinated with the International Hydrological Program (IHP) of UNESCO.

During its tenure the Commission plans to continue and emphasize areas in which it has traditionally been active, such as groundwater quality, environmental risk assessment and numerical modelling. In addition, it plans to develop new areas of emphasis, including innovative field and laboratory measurement techniques, advanced field data interpretation methods, characterization of heterogeneous media, and management of groundwater resources under uncertainty.

Projects undertaken by ICGW have resulted in significant contributions as reports and IAHS Red Books. The Commission also played a major role in several IAHS conferences.

Further information on ICGW is also contained in the Brochure of IAHS 80th Anniversary (pages 10,11)


Some 8 years have passed since the analysis of ICGW membership done by Past-President Mary Hill. We have revised the analysis of the international members of IAHS who manifested interested in the Ground Water Committee. We have requested IAHS the full list of members who expressed interest in the Ground Water Commission, updated at June 2016. The following figure shows the distribution of ICGW members all over the world.

Figure 1. World distribution of IAHS members who expressed interest in ICGW (updated June 2016)


The figure clearly shows the wide distribution of members, with very few countries where ICGW is completely absent.

Analysis of previous years memberships are available up to 2010. Figure 2 presents information similar to Figure 1, but showing the increase in membership by country for the period 2011-2016. Figure 3 shows the significant increase of members with interest in ICGW in Africa and Asia over the period 2011-2016. Figures 4-9 show the increase in membership between 2010 and June 2016 by continent and by country.

Figure 2. IAHS members who expressed interest in ICGW (updated June 2016): blue part of the chart represents memberships up to 2010 and the yellow part the new members for the period 2011-2016.
