The thesis gives an excellent discussion of our basic understanding of different wavemodes, using a full-waveform and multi-component approach. Focus lies on the dependency on porosity and permeability where especially the latter is difficult to estimate. In this thesis, this sensitivity is shown for interface and reflected wavemodes. For each of the pseudo-Rayleigh and pseudo-Stoneley interface waves, unique estimates for permeability and porosity can be obtained when impedance and attenuation are combined. The pseudo-Stoneley wave is most sensitive to permeability: both the impedance and the attenuation are controlled by the fluid flow. Also from reflected wavemodes unique estimates for permeability and porosity can be obtained when the reflection coefficients of different reflected modes are combined. In this case, the sensitivity to permeability is caused by subsurface heterogeneities generating mesoscopic fluid flow at seismic frequencies. The results of this thesis suggest that estimation of in-situ permeability is feasible, provided detection is carried out with multi-component measurements. The results largely affect geotechnical and reservoir engineering practices. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aPorous materials$xAcoustic properties$xMathematical models 606 $aFluid dynamics 615 0$aPorous materials$xAcoustic properties$xMathematical models. 615 0$aFluid dynamics. 676 $a620.1/064 700 $aDalen$b Karen N. van$01764101 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910437790803321 996 $aMulti-component acoustic characterization of porous media$94204830 997 $aUNINA
