  • Stochastic flow simulation in 3D porous media
    fluctuation assumptions are developed The hydraulic conductivity is modelled as an isotropic random field with a lognormal distribution and prescribed correlation or spectral functions It is sampled by a Monte Carlo method based on a randomized spectral representation The Darcy and continuity equations with the random hydraulic conductivity are solved numerically using the successive over relaxation method in order to extract statistical characteristics of the flow Hybrid averaging is used

  • Modelling of surface waves in poroelastic saturated materials by means of a two component continuum
    pdf PDF 1 2 MB Google View Download Kategorien Geomechanik Physikalisches Verhalten der Erde Geophysik Methodik Arbeitsmittel Abkürzungsverzeichnisse Geophysik Zur Langanzeige Zusammenfassung These lecture notes are devoted to an overview of the modelling and the numerical analysis of surface waves in two component saturated poroelastic media This is an extension to the part of the lecture notes by K Wilmanski WIAS Preprint No 945 which is primarily concerned with the classical surface waves in single component media We use the simple mixture model which is a simplification of the classical Biot s model for poroelastic media Two interfaces are considered here firstly the interface between a porous half space and a vacuum and secondly the interface between a porous halfspace and a fluid halfspace For both problems we show how a solution can be constructed and a numerical solution of the dispersion relation can be found We discuss the results for phase and group velocities and attenuations and compare some of them to the high and low frequency approximations For the interface porous medium vacuum there exist in the whole range of frequencies two surface waves a leaky Rayleigh wave and a true Stoneley wave For the interface porous medium

  • A comparison of Bayesian hierarchical space-time models for earthquake data
    hdl handle net 11858 00 1735 0000 0001 331A 5 Dateiname 07 04 pdf PDF 191 4 KB Google View Download Kategorien Signalanalyse Geophysik Zur Langanzeige Zusammenfassung Stochastic earthquake models are often based on a marked point process approach as for instance presented in Vere Jones 1995 This gives a fine resolution both in space and time making it possible to represent each earthquake with corresponding foreshocks and aftershocks separately However it is not obvious that this microscopic approach is advantageous when aiming at earthquake predictions In the present paper we take a macroscopic point of view considering grid cells of 0 5ʿx 0 5ʿ or about 50 km x 50 km and time periods of 4 months which seems suitable for predictions Hereby also the effects of foreshocks and aftershocks are circumvented More specifically we will discuss different alternative Bayesian hierarchical space time models in the spirit of Wikle et al 1998 For each time period the observations are the magnitudes of the largest observed earthquake within each grid cell In our models these largest observed earthquakes are represented by hidden system state variables called potentials The potentials at each time period and grid point are decomposed into a
