Abstract

En 中文

• First method to decouple elevation errors from pipe roughness calibration using residual standard deviation minimization. • Novel statistical framework isolates static elevation biases from dynamic pressure variability, avoiding parameter compensation. • Clustering-based preprocessing mitigates demand uncertainty and measurement noise for robust calibration. • Validated across three benchmark networks, enabling accurate roughness estimates without costly elevation surveys. • Transfers to real-world WDS with limited sensors or topographic data, enhancing model reliability for infrastructure management.
