Abstract
From the perspective of vegetation density, this research studies the influence of vegetation on turbulence characteristics and Reynolds shear stress in partly vegetated channel via a series of experiments. Natural reed is employed to simulate the emergent vegetation in rivers. Different vegetation densities including vegetated and unvegetated cases are considered in the research. The results of the research demonstrate that emergent vegetation may force the water flowing from vegetated areas to unvegetated areas and the forcing intensity increases with reed density. It is also found that the relative turbulence intensity declines along the vegetated channel in the direction of flow. Vegetation is found to reduce the total-average Reynolds shear stress therefore reduce the soil erosion. However, the Reynolds shear stress reduction is found disproportional to the vegetation density, and an optimal vegetation density range is quantitatively determined in the research. The findings of the research are significant to the practice of river ecological restoration.

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 it
