L'expérience algérienne dans le domaine des études de retenues collinaires The Algerian expérience in the domain of small dams studies
Bibliographic record
Abstract
SUMMARY The objective of this paper was to summarize the information obtained from studies of small dams in Algeria from 1987 to the present With the growing consumer demand, Algeria chose to maximize its surface water resources by the construction of small dams. Following the inadequate performance of these projects, the public administration re-evaluated its responsibility for designing small dams. The lack of experience with such studies resulted in a big investment in dam design. To improve this situation, the Algerian Consul ting engineers developed their own calculation methodology. In contrast to big dams, small dams are unique due to their particular characteristics. The studies hâve become more consistent and as a resuit the construction delays hâve decreased from 12 to 6 months, thus reducing the overall cost, which passed from 2 500 000 to 1 200 000 DA ($50 000 to $25 000) without affecting the quality and the reliability of the design. These improvements hâve been achieved thanks to a certain normalization of the studies and a rationa lisation of the tasks, such as the hydrological study, the geological and geotechnical investigations (bores, excavations, laboratory tests), the hydraulic design of the construction works, the calculation of the reinforced concrete works and the drawings. The reduction in delays was obtained thanks to technical improvements and Computing tools. The working studies were divided into six distinct projects: topographical; hydrological; geological and geotechnical; feasibility; plan ning; and call for tenders. The hydrological study highlights only essential parameters that are required for the continuation of studies. The geological and geotechnical study, performed on the basis of data collected in a recon naissance campaign and data from limited laboratory tests, defines the type of embankment required, considers the possible treatments for the foundations, and generâtes the geotechnical parameters needed for scaling the hydraulic structure.

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.
