Sinking Land: Optimal Control of Subsidence

Sen, Suphi; Verhoeven, Dewy; Weikard, Hans-Peter - 2023

Land subsidence threatens the living conditions of roughly 1.2 billion people worldwide in deltaic regions characterized by soft top soil. Economic activity in deltaic regions requires lowering the groundwater levels to keep the land sufficiently dry to maintain productivity, which, however,...

Evaluation of allowable withdrawn volume of groundwater based on observed data

Xu, Ye-Shuang; Huang, Run-Qiu; Han, Jie; Shen, Shui-Long - In: Natural Hazards 67 (2013) 2, pp. 513-522

To control land subsidence due to groundwater withdrawal, it is important to estimate allowable withdrawn volume of groundwater in a soft deposit. This technical note presents a simple approach for estimating the allowable withdrawn volume of a deposit. A regression analysis method was used...

Land subsidence caused by internal soil erosion owing to pumping confined aquifer groundwater during the deep foundation construction in Shanghai

Zhang, X.-S.; Wang, J.-X.; Wong, H.; Leo, C.-J.; Liu, Q.; … - In: Natural Hazards 69 (2013) 1, pp. 473-489

Land subsidence is presented in many factors in different areas with urbanization. Internal soil erosion, owing to pumping confined groundwater during the deep foundation pit construction, has contributed to land subsidence. Four governing equations are presented to describe the process of...

Causes of Land Subsidence in the Kingdom of Saudi Arabia

Amin, Ammar; Bankher, Khalid - In: Natural Hazards 16 (1997) 1, pp. 57-63

The occurrence of land subsidence in the Kingdom Saudi Arabia is either natural or man-made. Natural land subsidence occurs due to the development of subterranean voids by a solution of host rocks in carbonate and evaporite terrains, over many areas of Saudi Arabia. Man-induced land subsidence...
