• Koch, M., Seismicity and structural investigations of the Romanian Vrancea region: Evidence for azimuthal variations of P-wave velocity and Poisson's ratio, Tectonophysics,90, 91 - 115, 1982.

  A statistical analysis of local travel times of the Romanian Vrancea seismic region is performed and reveals lateral variations of the P-wave velocity and Poisson's ratio which are interpreted in terms of the geodynamics and of the petrology of the Carpathian subduction zone.

  A new 3D nonlinear inversion method including a full nonlinear 3D ray-tracing procedure is developed and applied to the inversion of teleseismic travel times and it is demonstrated that this method results in much less bias of the inverted structure of the lithosphere than the linear inversion approach used hitherto.

• Koch, M., Nonlinear inversion of local seismic travel times for the simultaneous determination of the 3D-velocity structure and hypocenters - application to the seismic zone Vrancea, J. Geophys., 56, 160 - 173, 1985.

  This paper describes the development of a new nonlinear inversion method for determining simultaneously 3D crustal structure and hypocentral locations and presents an application to determine for the first time the 3D lithospheric structure of the Romanian Vrancea seismic region and provides an interpretation in terms of the improved earthquake locations and of the geometry of the subduction zone.

• Koch, M. and D.A. Yuen, Surface deformation and geoid anomalies over single- and double-layered convective systems, Geophys. Res. Lett., 12, 701 - 704, 1985.

  A finite element method is used to model both whole mantle and two-layer mantle convection and the effects of the latter on the topography, gravity and geoid are studied as a function of the assumed viscosity contrast between the upper and the lower mantle and it is shown how the viscosity contrast affects these surface signals.

  The various authors apply their mantle convection codes on a a set of typical benchmark problems for mantle convection and compute some relevant parameters such as the internal temperature, the Nusselt number, and the topograpy and the geoid signals, compare them to each other, and discuss advantages and limitation of their codes.

• Koch, M., Methods, fallacies and challenges in seismic tomography, Supertimes, Newsletter of the Supercomputer Computations Research Institute, Florida State University, Tallahassee, FL, Fall 1991, 4 - 8, 1991.

  This paper reviews various known regularization methods to obtain stable solutions for the ill-posed linear seismic inverse probem, presents the development of some new techniques and applies all of them in a comparative manner to the 3D inversion of teleseismic travel-times and uses the methods to infere "optimal" lithospheric models.

  This paper discusses the origins of the difficulties in the numerical modeling of the advection diffusion equation when the advection term is dominating, presents the development of a new adaptive method of line, applies it to various forms of linear and nonlinear hyperbolic/parabolic flow problems arising primarily in porous media, presents the development of an inverse optimization method based on a quasi-Newton conjugate gradient method and applies the latter to the inversion of a real chemical chromatogram.

Ewing, C.A. Brebia, W.A. Gray and G.F. Pinder (eds.), pp. 149 - 156, Computational Mechanics Publications, Southampton, UK, 1992.

  A new mesh-adaptive collocation technique is developed and applied to the solution of the Buckley-Leverett equation which governs two-phase immiscible flow in the unsaturated zone of an aquifer or water-oil displacement flow in petroleum reservoir modeling and it is shown that the new method is able to better resolve saturation-shock like fronts than classical finite difference or finite element methods.

Ewing, C.A. Brebia, W.A. Gray and G.F. Pinder (eds.), pp. 155 - 162, Computational Mechanics Publications, Southampton, UK, 1992.

  The onset and development of hydrodynamic instability and fingering phenomena (Rayleigh-Taylor and Saffman-Taylor instabilities) in miscible, single phase, density- and viscosity-dependent solute transport in a porous media are studied by means of a mixed method of characteristics/ finite differences and the results are shown to compare favorably with predictions of a theoretical scaling analysis also developed here.

• Koch, M. and G. Zhang, Numerical simulation of the migration of density dependent contaminant plumes, Ground Water , 5, 731 - 742, 1992.

  Numerical simulations of density dependent contaminant plumes using a characteristics/ finite difference method are compared with an analytical scaling analysis and it is shown that, depending particularly on the solute concentration and on the value of the dispersivity of the aquifer, the migration of such plumes will be different from those where density effects are not considered.

  This paper is part I of a three-paper series and describes the development, validation and regularization properties of a new nonlinear inversion method which, contrary to other methods includes direct, refracted and reflected phases in the 3D ray tracing procedure and discusses results of numerical simulations on how to find optimal models in the tomographic inverse problem using local earthquakes.

  A new numerical method based on the idea of an influence function is developed to correct for the areas under overlapping variable T₁D_h relaxation signals in 13C cross-polarization NMR spectroscopy and is applied to determine in a more reliable way ratio's of the various functional carbon groups in structurally complex organic matter commonly encountered in organic geochemistry, such as peat from the Florida Everglades.

  The dynamics of density-driven miscible fingering in porous media is modeled numerically with the results demonstrating that the finger phenomenon behaves essentially as an initial-value controlled nonlinear dynamical system, however, with a self-similar or fractal geometric pattern whose fractal dimension has been determined as D = 1.56.

  This paper presents a finite-element analysis of experimentally observed creeping thermal plumes in a medium whose viscosity is strongly temperature-dependent, shows the numerical deficiencies of the method to model plumes with large viscosity contrasts, namely the inability of the method to enforce the div=0-condition, and proposes various new developments such as (1) better scaling of the fundamental equations, (2) use of an Augmented Lagrangian method and, (3) a multistep Newton method which is able to succesfully model the experimentally observed plumes.

  Using Monte Carlo realizations of the stochastic process for the Y = log K-permeability distribution in a heterogeneous porous medium, the dynamics and the morphology of density-driven fingers are modeled numerically and it is demonstrated that for the random medium, unlike in a homogenous medium where the evolution and the morphology of the finger instabilities are mostly affected by the initial instability- perturbation, it is its stochastic spatial realization that determines the fate of the fingers.

  Results of oil spill models operating on personal computers are compared to those operating on supercomputers when they are used for emergency response. The supercomputer model, which is a three-dimensional hydrodynamic model that computes currents using wind and tide predictions as input, appears to be superior to the PC model in predicting the future oil spill trajectory, particularly if scant observational data on earlier oil movement is available.

  The state of the art of oil spill modelling is reviewed and the necessity of highly efficient computational lgorithms for quick forecasting pointed out. A parallelized version of an oil-spill code is developed and implemented on a CM-2 Connection Machine and shown to allow real-time predictions of the fate and transport of an oil spill in case of an emergency.

  A new mesh-adaptive collocation technique is presented and applied to the efficient numerical solution of nonlinear single-and multiphase advection-dominated transport problems in porous media, as they arise in groundwater solute transport and petroleum reservoir modeling. Examples include, in particular, nonlinear adsorption, two-phase flow with capillary forces and Burgers' equation, all of which are notoriously difficult to solve by classical methods, but are easily solved by the new adaptive method.
