Calibrating Wastewater Hydraulic Model during Post Earthquake Rapid Rebuild Works

Abstract

Any modern water authority’s capital works program, operational/maintenance decisions, compliance with environmental consenting, future planning and programming works highly depend on the hydraulic modelling results. There are significant risks with this if the available models are not calibrated properly and if the model is not fit for purpose. As part of the post-earthquake rebuild process, 120 short-term and 13 long-term flow monitors were installed across different parts of Christchurch’s wastewater system. All these monitoring points needed to be calibrated to validate the wastewater network model and also to understand and assess the performance of wastewater network moving forward. Rapid changes in wastewater network configuration due to the fast tracked rebuild process created some unusual and unique challenges during calibration and validation works as the flow monitoring was done during different time periods and rebuild works forced the network to perform quite differently from time to time. This paper summarizes the challenges faced during model calibration and highlights the approaches adopted to address different calibration challenges and out-of-the-box scenarios.
