A method for the mathematical analysis of the cross-sectional geometry of tidal inlet channels
Journal of the International Association for Mathematical Geology - Tập 8 - Trang 635-647 - 1976
Analysis of channel cross sections is hindered by lack of parameters to describe the shape of the cross section. In the situation of a sample of cross sections taken across tidal inlets, if the cross section is expressed as an observation vector, principal-component analysis can be used to derive eigenvectors for the data set. By neglecting eigenvectors that explain little variance, mathematical r......
Rock Quality Designation Model Formulation and Simulation for Correlated Fracture Intact Lengths
Journal of the International Association for Mathematical Geology - Tập 32 - Trang 985-999 - 2000
An important factor in the rock quality assessment analysis from discontinuity measurements along a scanline is the correlation of intact lengths. The autorun model and first order autorun coefficient are proposed as a method for objectively quantifying intact length correlation structure and discontinuity occurrences along any scanline. Necessary definitions for the methodology are presented on a......

Macroscopic Electroosmotic Coupling Coefficient in Random Porous Media
Journal of the International Association for Mathematical Geology - Tập 33 - Trang 63-93 - 2001
A general analysis of electroosmotic phenomena is given for random porous media through which an electrolyte flows. A dimensional analysis demonstrates the crucial importance of the dimensionless coupling parameter a, which is usually very small when compared to 1; this suggests an expansion in terms of a and a numerical scheme that avoids the instabilities occurring in the direct solution. For me......

Stochastic models for the completeness of stratigraphic sections
Journal of the International Association for Mathematical Geology - Tập 21 - Trang 37-59 - 1989
Properties of stratigraphic completeness are determined here from a Brownian motion model of sediment accumulation. This avoids flaws inherent in application of a discrete-time random walk to the time span, rather than thickness, of sediment layers. Both discrete and continuous models show that the concept of stratigraphic completeness is meaningful only when the time scale is specified. From the ......
