Electrical resistivity tomography (ERT) is widely used to image the Earth's subsurface and
has proven to be an extremely useful tool in application to hydrological problems …

Ground surface dynamics is one of the processes influencing the future of the Wadden Sea
area. Vertical land movement, both subsidence and heave, is a direct contributor to changes …

Satellite radar data were used to estimate subsurface model parameters of the Bergermeer
gas field. Directly using combinations of the line-of-sight measurements in both ascending …

Deformation during CO 2 injection can lead to problems, like seismicity or fluid leaks, but
small strains have the potential to be a useful signal for monitoring. The objective of this …

Anthropogenic land subsidence can be evaluated and predicted by numerical models,
which are often built over deterministic analyses. However, uncertainties and …

Groundwater level knowledge is one of the crucial information for sustainable use of
groundwater resources and efficient and effective conjunctive management of surface and …

Although the beginning of reservoir geomechanics dates back to the late 1960s, only
recently stochastical geomechanical modelling has been introduced into the general …

Here a numerical technique based on the method of lines (MoL) for solving Richards'
equation is presented. The Richards' equation deals with modeling infiltration of water into …

In recent years, the awareness about the critical importance of correctly dealing with
uncertainty in numerical models is spreading over an increasing number of application …

In this paper a new data assimilation technique is proposed which is based on the ensemble
Kalman filter (EnKF). Such a technique will be effective if few observations of a dynamical …
