Join us for an insightful presentation examining how integrated hydrologic modelling can improve our understanding of groundwater flooding and support more effective flood risk management in urban environments.
Presentation Title: An Integrated Surface Water and Groundwater Model Case Study to Assess the Effects of Groundwater Flood Events
Abstract:
Jens Schumacher and Gordon MacMillan; Fluid Domains
This presentation will describe the numerical modelling work undertaken to assess the impacts of groundwater flooding in the City of Calgary. Groundwater flood events are estimated to contribute up to one-third of Calgary's average annual flood damage exposure (IBI, 2017).
An integrated modelling approach using HydroGeoSphere was employed to simulate the strong, dynamic, and bi-directional interactions between surface water and groundwater flow, which were considered essential for groundwater flood modelling.
The modelling decisions made to achieve the project objectives will be discussed, with particular focus on the calibration strategy and the methods used to evaluate structural and parameter uncertainties and their effects on model predictions. The presentation will also demonstrate how PEST was coupled with HydroGeoSphere to automate model calibration and support parameter uncertainty analyses. The results of the groundwater flood simulations, together with their associated uncertainties, will be presented.
