Sediment response to catchment disturbances
Bibliographic record
Abstract
The surface of the planet undergoes a constant battle for balance between uplift and erosion. Plate tectonics cause land to be created and mountains to be born, while weathering and erosion act to lower the land surface. Rivers transport the products of weathering and erosion to storage points, or sinks; the ultimate sink being the deep oceans. For a given landscape, an equilibrium is reached whereby the rates of sediment distribution between sources and sinks are fairly constant. In the case of a river channel, the amount of water and sediment moved through a landscape is balanced by the energy available to do this, such that a change in either of the two generates adjustments in stream power. A change in environmental conditions often results in a response, the magnitude of which is a function of the type and intensity of “disturbance” to the system. In the case of the river channel, this might manifest itself in the form of channel aggradation or degradation, whereby sediments are either deposited or eroded in response to changes in available energy or sediment supply.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
