A Preliminary Study on the Geoscientific Significance of the Core from Cangzhou Scientific Drilling Hole [PDF]

open access: yesE3S Web of Conferences
The Cangzhou area is one of the regions in China most severely affected by groundwater over- exploitation and land subsidence. To further elucidate the deep geological structure of this area and facilitate dynamic monitoring of key strata compression ...

The case for dynamic subsidence of the U.S. east coast since the Eocene [PDF]

open access: yes, 2008
The dynamic subsidence of the United States east coast is addressed using the discrepancy between regional and global estimates of sea level, elevation of paleoshorelines, and adjoint models of mantle convection that assimilate plate motions and seismic ...

Novel MRI-based vertebral bone quality score as a predictor of cage subsidence following transforaminal lumbar interbody fusion.

open access: yesJournal of Neurosurgery : Spine, 2022
OBJECTIVE Decreased bone mineral density as measured by dual-energy x-ray absorptiometry (DEXA) has been reported to be associated with cage subsidence following transforaminal lumbar interbody fusion (TLIF).

Constructing a Large-Scale Urban Land Subsidence Prediction Method Based on Neural Network Algorithm from the Perspective of Multiple Factors

open access: yesRemote Sensing, 2022
The existing neural network model in urban land-subsidence prediction is over-reliant on historical subsidence data. It cannot accurately capture or predict the fluctuation in the sequence deformation, while the improper selection of training samples ...

Spatiotemporal heterogeneity of land subsidence in Beijing

open access: yesScientific Reports, 2022
Land subsidence induced by groundwater level decline has spatiotemporal variations. Taking the Interferometric Synthetic Aperture Radar (InSAR) results and the groundwater subsidence data acquired by the monitoring stations as the source material, this ...

Prediction of subsidence due to underground mining by artificial neural networks [PDF]

open access: yes, 2003
Alternatively to empirical prediction methods, methods based on influential functions and on mechanical model, artificial neural networks (ANNs) can be used for the surface subsidence prediction.

Three-Dimensional Surface Displacement of the Eastern Beijing Plain, China, Using Ascending and Descending Sentinel-1A/B Images and Leveling Data

open access: yesRemote Sensing, 2021
Surface displacement is an common environmental geological phenomenon in the Beijing Plain. Research on surface displacement in the Beijing Plain has mainly focused on vertical surface displacement, whereas the horizontal displacement has scarcely been ...

Formation of offshore tidal sandbanks triggered by a gasmined bed subsidence [PDF]

open access: yes, 2002
Offshore gasmining is an example of a human intervention with a morphological impact. On land, it is usually attended with a dish-like bed depression.
