Possible Re-Alignment of the Lower Mississippi River and Influences on Navigation
Bibliographic record
Abstract
This paper presents the navigation implications of a possible Mississippi River mouth re-alignment plan from the perspective of one of the teams selected to compete in the changing course design competition (see changingcourse.us and deltaforall.com for more information). The goals of the competition are to: create a sustainable and functioning deltaic system in areas adjacent to the Mississippi River and below New Orleans; continue to meet the needs of navigation, flood protection and coastal industries and communities; contribute additional innovation, competition, and private sector engagement in time to inform Louisiana’s next coastal master plan in 2017 in terms of a possible option for river mouth re-alignment. In this design competition, the primary challenges arise from the meeting of the natural and built environments and the tremendous changes underway. Navigation, shipping, fisheries, coastal industries, communities, and wetland health all face tremendous pressure from these changes. This paper presents a river mouth re-alignment alternative that would provide for a smaller but sustainable delta footprint, at the same time as providing immediate opportunities for dramatic flood risk reduction and a massive upgrade to the navigation system.

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.
