Abstract
The application of geomorphic principles to land reclamation after surface mining has been reported in the literature \nsince the mid-1990s, mostly from Australia, Canada and the USA. This paper discusses the reclamation problems of contour \nmining and quarries on slopes, where steep gradients are prone to both mass movement and water erosion. To address these \nproblems simultaneously, a geomorphic model for reclaiming surface mined slopes is described. Called the ‘highwall–trench– \nconcave slope’ model, it was fi rst applied in the 1995 reclamation of a quarry on a slope (La Revilla) in Central Spain. \nThe geomorphic model does not reproduce the original topography, but has two very different sectors and objectives: (i) the \nhighwall–trench sector allows the former quarry face to evolve naturally by erosion, accommodating fallen debris by means of a \ntrench constructed at the toe of the highwall; (ii) the concave-slope base sector, mimicking the landforms of the surrounding \nundisturbed landscape, promotes soil formation and the establishment of self-sustaining, functional ecosystems in the area \nprotected from sedimentation by the trench. The model improves upon simple topographic reconstruction, because it rebuilds \nthe surfi cial geology architecture and facilitates re-establishment of equilibrium slopes through the management and control of \ngeomorphic processes. \nThirteen years of monitoring of the geomorphic and edaphic evolution of La Revilla reclaimed quarry confi rms that the area is \nfunctioning as intended: the highwall is backwasting and material is accumulating at the trench, permitting the recovery of soils \nand vegetation on the concave slope. However, the trench is fi lling faster than planned, which may lead to run-off and sedimentation \non the concave slope once the trench is full. The lesson learned for other scenarios is that the model works well in a twodimensional \nscheme, but requires a three-dimensional drainage management, breaking the reclaimed area into several watersheds \nwith stream channels.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
