Abstract
Comoé Dam in Burkina Faso is an embankment dam of 24 m maximum height above the riverbed and around 1170 m crest length. The dam foundations on the abutments are lateritic ground made of a superficial hard duricrust covering a lateritic carapace, soft to firm layer of 6 to 10 m thickness with canaliculus and cavities. The bedrock is made of highly weathered dolerite at the top, sound and watertight at depth. Since the first impoundment of the dam in 1991, uncontrolled seepage appeared at the downstream toe of the embankment on both abutments, particularly on the left bank. Seepage flow gradually increased with time. In 2010, the situation became critical with development of subsidence downstream in the left abutment. Remedial works launched in 2013 included a positive sheet piles cutoff of 40 m maximum depth, tubes-à-manchettes grouting and compaction grouting. Because of the political crisis and economic difficulties, works stopped before completion of compaction grouting and tubes-à-manchettes grouting on the left bank. Although remedial works have not been completed, already a significant reduction in seepage flow and pressures has been observed.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
