Risk assessment of a water supply system under climate variability: a stochastic approach
Bibliographic record
Abstract
A model is developed to assess risk to a municipal water supply system under the influence of population growth and climate variability. To incorporate the uncertainty in water use, a model that combines time series Monte Carlo simulations and a deterministic artificial neural network (ANN) is developed to simulate the daily water demand under climate variation. The model is first applied to assess how climate change alters the risk of a current water supply system and is then used to estimate the effects of demand management programs and system expansion. The model quantifies water supply system risk in terms of reliability, resiliency, and vulnerability (RRV). The model evaluates 11 scenarios defined by combining various population growth forecasts, demand management programs, system expansions, and global climate model (GCM) scenarios. The simulation results suggest that a rise in temperature and a change in precipitation magnitude will negatively impact the performance of the case study system.

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.
