Extraction of groundwater can lead to significant subsidence, including depression of the ground surface or fissuring of the ground. Damage to property and infrastructure and increased flood potential, particularly in coastal plains and deltas, result from these ground movements. Problems are already widespread in areas that rely primarily on water supply from groundwater reservoirs and are becoming more extensive as exploitation of groundwater increases particularly in arid and semi-arid areas. This working group has been convened to examine the nature, extent and mechanisms of subidence associated with groundwater withdrawal and methods for recharging aquifers to reduce the impacts of these ground movements.
The Chairman if the Working Group is Prof Dr Qingcheng He.
