Improving confidence in CSO spill prediction: Automating model verification to 3 years of data.
The study presented in this paper proved successful and significantly advanced the understanding of how optimisation can be applied to improve model calibration for CSO spills.
Presented at CIWEM UDG 2025, this accompanying paper demonstrates how HEEDS optimisation can automate CSO model verification using multi-year EDM and groundwater data. The workflow calibrates runoff, infiltration and seasonality parameters automatically, achieving spill predictions within ±20% accuracy across 10 sites.
This HEEDS driven process reduces engineer time, improves consistency, and lays the foundation for continuous calibration as new data becomes available.
