Modeling of Hydrodynamic Regimes for the Thuan An Estuary
Bibliographic record
Abstract
Located in the southeast of Hue city in Thua Thien Hue province, Thuan An estuary plays a crucial role as a waterway and flood drainage pathway for the Huong River. Importantly, the morphology of the Thuan An estuary has been subjected to continuous change during monsoon seasons with the process of sediments in the estuary and erosion along the northern and southern coasts. Remarkably, the process of sediments directly impacts flood drainage and navigation along the waterway, as well as the sustainable development of Thua Thien Hue marine economy. Therefore, the goal of this study is to insightfully provide hydrodynamic regimes using a Delft3D model combined with ArcGIS software. The results showed that the estuary is wave-dominated lowland coasts. The coastal barrier is formed from sand that is transported along the shoreline by wave-driven longshore currents. During the northeast monsoon, river flow is significantly small, tidal currents combine with longshore currents by waves to form a strong longshore current with direction from northeast to southwest. Whereas, during the southwest monsoon, the sandbar extending from the southern side expands northward, leading to sedimentation accumulation at the river mouth channel. Specifically, a sandbar is formed at the river mouth with an accumulation of up to about 0.8 m.

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.
