Abstract
Net and directionally-related mean sediment transport rates have been calculated for two stations within an estuarine system, using self-recording current meter and wave data. Analysis of the data set shows that: (1) because the relationship between sediment transport rate and near-bed current velocity is non-linear, the direction of net sediment transport may differ significantly from, or oppose, that of the near-bed residual current velocity; (2) in response to rotatory tidal currents and increasing wave action, net transport rates may remain unchanged-hence, it is the directionally-related mean transport rates (rather than the net transport rate itself) which should be used to describe the mobility of seabed sediments (such an observation implies that the time-scale on which the net sediment transport rate is meaningful is controlled by the time-scale on which changes in seabed morphology take place); and (3) under the influence of a combination of wave action and time-asymmetry of the tidal currents, changes in the direction of net transport rates may occur, implying that net transport during calm periods may reverse during storm periods.

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
