Abstract

This work aims to examine the influence of the variability of the initial apertures on dissolutional growth of fissures and the evolving cave systems. To this end, the initial apertures were spatially uncorrelated and lognormally distributed and the influence of the coefficient of variation of the aperture data (σ/μ) was investigated in several scenarios on the basis of a set of 4 realisations. It is found that a small degree of heterogeneity leads to cave patterns similar to those obtained with uniform initial apertures. However, with increasing heterogeneity the karstification process decelerates and a significant amount of variability between the different realisations follows
