Abstract
Changes in runoff and sediment transport in the Middle Reach of the Huai River have been studied by using 58 years of field data. The runoff yield from the Huai River watershed mainly occurs in the sub-watershed of the river. At the downstream Wujiadu station, the difference in total drainage area between the south and the north branches of the river is 43% while the difference in runoff yield is only 9%. Sediment yield mainly comes from the headwaters in the northern region with the upstream of the Huai River playing a secondary role. The data demonstrate that there has been little change in long-term average annual runoff in the Middle Reach of the Huai River (MRHR) but there has been a dramatic decrease in average annual sediment transport. This decrease in sediment transport in the Huai River has resulted in changes in the geomorphology of the Middle Reach of the Huai River with time. Further analysis indicates that both the main channel and the floodplain of the estuary of Hongzehu Lake have a tendency towards the deposition of sediment. A trend and regression analysis is used in the compilation of field data, calculations, and analysis.

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
