This paper describes the use of a unique spatio-temporally resolved precipitation and temperature dataset to assess the spatio-temporal dynamics of water resources over a period of almost seven decades across the Sierra Nevada mountain range, which i

Closed depressions are scale-invariant landforms that are the most distinctive and characteristic landform in karst terrains at the millimetre-to-kilometre scales. The purpose of this paper is twofold. The first is to raise awareness of the geoherita

This paper investigates the relationship between rainfall, groundwater and Gravity Recovery and Climate Experiment (GRACE) data to generate regional-scale estimates of terrestrial water storage variations in the Andalucía region of southern Spain. T

Many features of a karst massif can either be modelled using fractal geometry or have a fractal distribution. For the exokarst, typical examples include the geometry of the landscape and the spatial location and size-distribution of karst depressions

Digital elevation models (DEM) are digital representations of topography that are especially suitable for numerical terrain analysis in earth sciences and engineering. One of the main quantitative uses of DEM is the automatic delineation of flow netw

The objective of the work presented in this paper is to provide a quantitative measure of grade heterogeneity at the selective mining unit scale within relatively large estimated resource blocks. The purpose of the work is to provide a means of evalu

Traditional geostatistical simulation techniques rely on the assumption of multi-Gaussianity. Although the normal score transform is widely used to convert data to a Gaussian distribution, it only guarantees that the normal scores will be univariate

Closed terrain depressions are geomorphic features that show scale invariance over the wide range of scales on which they occur, from metres to thousands of kilometres. They are also global features that are present on all continents. Morphometric an

One of the most challenging aspects of multivariate geostatistics is dealing with complex relationships between variables. Geostatistical co-simulation and spatial decorrelation methods, commonly used for modelling multiple variables, are ineffective

In rock physics and petrological applications, pore identification from cast thin-section (CTS) images is a widely used means of estimating porosity and evaluating types of pores and pore structure parameters. Common problems encountered in current a
