Flood Resilience Digital Twin (FReD): Empowering decision makers for improved management of flood risk
Date 2022 Authors Matthew Wilson, Greg Preston, Casey Li, Xander Cai, Luke Parkinson, Rose Pearson, Rob Deakin, Emily Lane Abstract Flood inundation is a frequent, widespread, and impactful hazard, which regularly causes damage to housing and infrastructure along with disruption to communities and businesses. Further, flood risk is expected to increase in future, due to […]
Uncertainty in Bathymetry Estimation
Date September 5-6, 2023 Submitted to The Fourth Spatial Data Science Symposium Authors M. Nguyen, M. D. Wilson, E. M. Lane, J. Brasington, R. Pearson Introduction River bathymetry plays a crucial role in flood modelling in the form of Digital Elevation Model (DEM). It increases the reliability, accuracy and continuity of the DEM. However, river […]
Building Future Urban Development Scenarios into Assessments of Future Flood Risk
Date September 5-6, 2023 Submitted to The Fourth Spatial Data Science Symposium Author Katherine Booker Supervisors Professor Iain White, University of Waikato and Professor Matthew Wilson, GRI University of Canterbury Research Problem The devastating impact of flood events demonstrates the need for more comprehensive assessments of future flood risk in urban policy. Risk assessments based […]
Data processing for flood risk assessments
Project summary Alongside the uncertainty research, the GRI is working with NIWA to help produce consistent, open-source methodology for the national flood risk assessments. The methods developed are guided by a number of physically-based flood inundation modelling efforts that have been attempted internationally both at national and global scale. The research programme is specifically addressing […]
Uncertainties in flood risk assessments
Project summary Flooding is one of New Zealand’s most damaging hazards. This research programme is supporting the changes that are needed to our flood risk management. The overall aim of the programme is to provide the first, high-resolution flood hazard assessment for every catchment in the country. The research is producing New Zealand’s first consistent, […]
Digital Twin Digital Twin for Flood Resilience
Project summary This project aims to create a “digital twin” prototype as a proof-of-concept system to assist with more efficient flood risk management. Flood inundation is a frequent and impactful hazard that can cause significant damage to infrastructure, housing, and communities. This technology creates a digital representation of an entity such as a building, city […]
USING RISKSCAPE TO MEASURE THE IMPACT OF FLOOD UNCERTAINTY ON DECISION-MAKING
Date 7 November 2023 Submitted to The Waterways Postgraduate Student Conference Author Clevon Ash Supervisors Prof Matthew Wilson, Prof Iain White, and Dr Carolynne Hultquist Abstract Flooding is a major hazard in Aotearoa. In 2022 and 2023 alone, the combined cost of damage was more than 3.5 billion dollars. To address this problem, flood hazards […]
Analysis of New Zealand daily weather patterns (DWTs) and large-scale climatic patterns as extreme rainfall and flooding drivers
Research team Andrea Pozo, Matthew Wilson, Marwan Katurji, Fernando Méndez, Emily Lane Summary The overall aim of this research project is the generation of flood inundation maps for a specific study site, namely the Wairewa catchment (Little River, Canterbury) for the benefit of community stakeholders. To this end, accurate analysis and characterization of extreme rainfall […]
Reducing Flood Inundation Hazard and Risk across Aotearoa New Zealand
Flooding is one of New Zealand’s most damaging hazards, which will also change the most rapidly in intensity and nature as a result of climate change. At the same time, urban development is leading to increased flood exposure. These dual challenges make reducing flood risk extremely difficult for our current planning and response systems. There […]
