Abstract

fetched live from OpenAlex

The sensitivity of Blue Nile flows (which contribute the bulk of the Nile water) to changes in future rainfall during the June-September rainy season based on output from three General Circulation Models (GCMs) was determined up until 2100. The study attempted to quantify uncertainties arising from: (a) use of different GCMs; (b) different greenhouse gas emissions scenarios; and (c) downscaling coarse-scale GCM output to a finer-scale required for hydrological modelling. A multidimensional stochastic rainfall generator was developed to produce high-resolution gridded rainfall data required by the distributed hydrological model (Nile Forecast System). The assessment also incorporated future evapotranspiration changes over the basin, although in a more simplistic way. Two of the GCMs (Canadian Climate Centre's CGCM2 and UK Hadley Centre's HadCM3) led to reductions in future mean flow and Q5 (daily flow exceeded 5% of the time) during the rainy season, whilst use of the third GCM (Max Plank Institute's ECHAM4) led to general increases in future mean flow and Q5. Changes were more pronounced by the 2050s and 2080s.

Full frame distilled prediction

Teacher imitation

Not 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.
