Land subsidence and associated earth fissures attributed to ground water pumping are ongoing problems in many areas of the United States and throughout the world. In susceptible regions, the overlying developed ground water systems experience nonrecoverable vertical and horizontal movement of the land surface that disturbs infrastructure. These situations frequently increase risk of riverine and coastal flooding, and typically contribute directly and indirectly to other environmental hazards. The consequences associated with the development of ground water resources are constraints on the sustainable management of the affected regions' water resources. For subsidence and earth fissures related to ground water pumping, this session explores case studies of recently detected areas and updates on existing problem areas; innovative methods of mapping, measuring, and monitoring; mitigation strategies; methods for modeling; and sustainable water resources management in problem areas.
