7. 5. Risk Assessment of Groundwater Drawdown in Subsidence Sensitive Areas

   Author : Jonas Sundell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse modelling; cost-benefit analysis; probabilistic; groundwater drawdown; urban hydrogeology; economic valuation; groundwater leakage; subsidence; value of information analysis.; spatial variability; uncertainty quantification; risk assessment;

   Abstract : Groundwater leakage into sub-surface constructions can result in drawdown, subsidence in compressible materials, and costly damage to buildings and installations. When planning for sub-surface constructions where there is a risk for land subsidence due to groundwater drawdown, the need for safety measures must be carefully evaluated and managed. READ MORE
