We present an analysis of ground deformation induced by large-scale seasonal rainfall in Southern Africa, based on GPS and GRACE time series simulations elastic flexural response to hydrological loading. This study including South Zambia, Angola, North Namibia Botswana displays a latitudinal precipitation gradient between tropical semi-arid conditions. data display annual variations water mass ...

Underground coal mining often causes persistent land subsidence, which would lead to huge threats to infrastructure and safety in the coal area [1, 2]. Traditional levelling and GPS methods are able to produce reliable measurement of ground subsidence [3]. However, these field surveys are time-consuming and cannot provide deformation map with high spatial sampling density. Synthetic aperture ra...

Deep porous reservoirs are subject to charge and discharge of fluids (oil, gas or water), either naturally or induced by human exploitation. This leads to a variation in pressure inside the reservoir and consequently to a deformation of the overlying material. The knowledge of the ground surface displacements allows inferring the fluid migrations and the hydromechanical properties in the porous...

This paper introduces a method to estimate deformation of elastic bodies using monocular camera images. As this issue is originally an ill-posed problem, sparse constraints are used in the objective function. Using a motion capture system, estimation performance is evaluated by the ground truth deformation of a rubber object. The results show that 12 patterns of elastic deformation by a pull of...

the ground reaction curve (grc) is a vital component of the convergence-confinement method, which possesses many applications in the underground space designs. it defines a relation between the tunnel wall deformations and the ground pressure acting on the tunnel walls. generally, grc includes descending and ascending branches. according to many researchers, the descending branch trend for the ...

Abstract. Monitoring ground deformation at national and regional level with millimetre-scale precision, nowadays, is possible by using Advanced Differential Interferometric SAR (A-DInSAR) techniques. This study concerns the results of European Ground Motion Service (EGMS), part Copernicus Land Service, which detects measures land displacement scale. provides reliable consistent information rega...

Full three dimensional static and dynamic mean field calculations using collocation basis splines with a Skyrme type Hamiltonian are described. This program is developed to address the difficult theoretical challenges offered by exotic nuclei. Ground state and deformation properties are calculated using static HartreeFock, Hartree-Fock+BCS and constrained Hartree-Fock models. Collective propert...
