Abstract
The retreat of the coastline, especially fast in areas with sand dunes of Pleistocene-Holocene unconsolidated deposits, is becoming a very serious problem in zones where towns, fishery villages, holiday houses and hotels are present. About ten years ago, decision-makers decided to build groins and revetments thinking the problem solved. However, the problem was not solved and each year the engineering coastal structures became increasingly hard, the groins increased and, simultaneously, the retreat of the cliffs accelerated while the beaches lost sediments. Now the challenge is to find an alternative that can effectively protect the damaged occupied areas and to prevent the accelerated downdrift erosion. One alternative measure could be artificial beach, nourishment successfully done in Praia da Rocha (Algarve). However, this practice is not useful on other segments of the Portuguese coastline where source sediments are not available. Two different and illustrative examples of the kind of protection and management that has been done on the Portuguese coastline discussed for the Ofir-Apulia and the Espinho-Furadouro areas.

How this classification was reachedexpand
Full frame distilled prediction
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.
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; both teacher heads agree on what is shown here.
