“…Earlier studies on the spatial distribution of fluid flow and hydraulic properties on artificial ecosystems such as mine spoils observed high spatial heterogeneity (e.g. Buczko et al, 2001;Buczko and Gerke, 2005;Webb et al, 2008). Contrary, our findings showed that on material subjected to artificial separation, spatial variability can be very low.…”

“…The few studies conducted on mine waste disposal facilities or artificial catchments are based on indirect methods involving analysis of qualitative data on soil structure (Breshears et al, 2005;Buczko et al, 2001), while results of spatial analysis are often not reported probably due to small sample sizes that restrict such analysis (Gerwin et al, 2009;Holländer et al, 2009;Mazur et al, 2011;Wehr et al, 2005). Notable exceptions are two studies conducted in Germany, where geostatistical analysis of hydraulic parameters derived from pedotransfer functions developed for natural soils showed that particle segregation during transportation and dumping, and amelioration practices contributed to spatial variability on lignite mine spoils (Buczko et al, 2001;Buczko and Gerke, 2005). A dye tracer study conducted on covers in New Mexico, USA, a decade after installation showed that macropores caused by root intrusion and fauna enhanced drainage (Breshears et al, 2005).…”

“…In summary, analysis of existing studies suggests that K s integrates numerous complex interactions between the material properties, material handling and construction procedures and the effects of biological activities such as biointrusion and macroporosity (Breshears et al, 2005;Buczko et al, 2001;Buczko and Gerke, 2005;Webb et al, 2008). As the application of 2-D and 3-D water balance and solute transport models becomes increasingly common, it is critical to account for K s spatial variability in both horizontal and vertical directions.…”

“…Gerke, 2006). For modelling such overburden spoil piles, the spatial heterogeneity of sediment texture and bulk density was considered by taking technical dumping and mixing processes into account (Buczko and Gerke, 2005a). Experiments in 2-D-slab cells by Lebron and Robinson (2003) suggested that internal layering of different grain sizes can occur due to avalanching processes.…”

“…It remains challenging to transfer such sediment structures into hydraulic and transport properties such that the predicted flow paths reflect the internal structure of the artificial system not only for cross-sections (e.g. Buczko and Gerke, 2005b) but for catchments.…”

Abstract. Artificially-created hydrological catchments are characterised by sediment structures from technological construction processes that can potentially be important for modelling of flow and transport and for understanding initial soil and ecosystem development. The subsurface spatial structures of such catchments have not yet been sufficiently explored and described. Our objective was to develop a structure generator programme for modelling the 3-D spatial distribution patterns of dumped sediments depending on the technical earth-moving and deposition processes. We are focussing in a first step on integrating sediment dumping, particle size, and bulk density modification processes on the catchment scale. For the model development, the artificially-constructed hydrological catchment "Chicken Creek" located in Lower Lusatia, Germany, served as an example. The structure generator describes 3-D technological sediment distributions at two scales: (i) for a 2-D-vertical cross-section, texture and bulk density distributions are generated within individual spoil cones that result from mass dumping, particle segregation, and compaction and (ii) for the whole catchment, the spoil cones are horizontally arranged along trajectories of mass dumping controlled by the belt stacker-machine relative to the catchment's clay layer topography. The generated 3-D texture and bulk density distributions are interpolated and visualised as a gridded 3-D-volume body using 3-D computer-aided design software. The generated subsurface sediment distribution for the Correspondence to: T. Maurer (maurer@tu-cottbus.de) Chicken Creek catchment was found to correspond to observed patterns already without calibration. Spatial aggregation and interpolation in the gridded volume body modified the generated distributions towards more uniform (unimodal) distributions and lower values of the standard deviations. The modelling approach is generally applicable to all situations where large masses of unconsolidated sediment are moved and dumped thereby allowing generation of basic soil structures and patterns of hydrological systems.
