Global Groundwater Information System - GGIS
A GGIS is an interactive and transparent portal to groundwater-related information and knowledge. The system is meant for various categories of stakeholders, including both professionals and the general public. The GGIS is simple to use and completely publicly accessible. It leads the user from aggregated, global information (Global Overview) via related information sources (Meta-Information Module) towards a direct information exchange (Collaborative Environment). Global Groundwater Monitoring Network (GGMN) is the youngest and the most demanding GGIS module. Its purpose is to monitor a global change of groundwater resources.

GW-MATE - World Bank Groundwater Management Advisory Team
The GW-MATE initiative is designed to support the thrust from 'vision to action' on integrated water resources management of the World Water Forum in March 2000. GW-MATE is a core group of experienced specialists in the multidisciplinary and multifaceted area of groundwater management. In essence, the GW-MATE is operational in mode, interdisciplinary in character, and advisory in style.

International Groundwater Assessment Centre
IGRAC is dedicated to groundwater information and knowledge in the widest sense, on a world-wide scale and on a non-commercial basis. The World's groundwater resources are of key importance to sustainable development. However, making full benefit from the available groundwater resources and controlling effectively the ubiquitous groundwater-related problems are very demanding tasks. Sharing groundwater information and experience on a world-wide scale would be of great help in this respect. This is what IGRAC supports and promotes.

Participatory Groundwater Management
More than 2 billion people worldwide depend on groundwater for their daily supply. Major agricultural economies (North China, South Asia, North Africa/Middle East) depend on groundwater. Yet this positive developments have in many areas come at a price - falling groundwater tables and deteriorating groundwater quality. In many places Participatory Groundwater Management has a possible important role to play to addresss these issues - alongside other measures. To bring together the scattered experience and to equip persons keen to promote participatory groundwater management this training kit has been prepared. 8 PowerPoint modules and additional material.

British Geological Survey - Groundwater real-time data
The BGS collect groundwater level data in many of our research projects, and we host the National Groundwater Level Archive, the national repository for groundwater level data. We are currently working to make groundwater level data available via this website. You can view information on a limited number of sites. Why monitor groundwater levels? Measuring the groundwater level in a well in Scotland Groundwater level, as measured in an observation borehole, reflects the amount of water in storage in the monitored aquifer. When recharge exceeds natural discharge plus abstraction, groundwater levels rise. When recharge is less than natural discharge plus abstraction, groundwater levels fall. Comparisons of measured groundwater levels with long-term averages provide an indication of the state of groundwater resources within an aquifer. Observation over several years allows the prediction of aquifer response to current climatic and hydrological conditions. The data from the archive are used to prepare archive products such as the monthly hydrological summaries, annual summaries and the statistics volume. The data are used for quantitative analyses, for instance of annual recharge, and provide a valuable source of data for the calibration of groundwater models.

Hyporheic Network - Knowledge Transfer Network
Welcome to the homepage of the Hyporheic Network - a Knowledge Transfer network on groundwater - surface water interactions and hyporheic zone processes. The hyporheic zone is located at the interface of aquifers and rivers, and comprises the sediments in which there is exchange and mixing of groundwater and river water. It is an important zone for pollutant, energy and carbon cycling, and may be an important component of the riverine habitat.

International Symposium on groundwater Sustainablity (ISGWAS)
24-27 January 2006, Alicante, Spain. Achieving the long-term sustainable use of groundwater resources will depend as much on understanding socio-economic forces as on effectively monitoring and modelling climatic and hydrogeologic conditions. It is important to develop adequate monitoring and information networks, but it is also imperative to understand what institutional arrangements, economic incentives, legal structures and educational initiatives can be developed to insure the long-term sustainability of groundwater development and use throughout the world. This symposium will bring together experts from different disciplines and regions of the world in order to discuss challenges and propose solutions to contribute to the long-term sustainability of groundwater resources.
