Led by Te Whare W膩nanga o Waitaha | 91制片厂 (UC) Professor Matthew Wilson, UC researchers are developing tools to enhance the accuracy and efficiency of flood modelling.
"The work focuses on flood risk assessment and hydrology using digital twins鈥攃omputer simulations powered by geospatial data and cloud computing鈥攖o model and visualise floods and their potential impacts." Professor Wilson, Director of the Geospatial Research Institute | Toi Hangarau says.
The models predict the effects of extreme rainfall, considering climate change and urban growth, and offer insights for disaster response and planning.
"Obviously, we know the areas that flood regularly because of past experience, but our system allows assessment of less frequent or more extreme events that might occur鈥攑articularly with climate change. It can also be used to consider how future flood risk could change with additional urban development," he says.
A successful prototype has already been developed in New Zealand, and the team is working to implement the model on a cloud computing system, enabling faster and more efficient flood risk assessments across the country.
As part of new MBIE-funded research, the model is currently being extended to explore flood mitigation scenarios, including nature-based solutions such as wetland restoration and native forest planting.听
鈥淭hese approaches not only reduce flood risk but also provide additional environmental benefits, which the model will quantify and compare to other scenarios such as hard engineering infrastructure.鈥
The next step for the team鈥攕caling the technology to enable implementation anywhere globally鈥攑resents significant challenges. However, a Fellowship provides a valuable opportunity to advance this work. Professor Wilson, one of four recipients of the 2024 inaugural IIT Delhi India-New Zealand Centre Fellowships, will head to India in March to collaborate with water resource researchers in the Department of Civil Engineering at IIT-Delhi.
鈥淢y fellowship at IIT Delhi will support this work, providing a valuable opportunity to collaborate with researchers in India. With open-source data and software, we can share ideas, technology, and insights while applying the technology in an Indian context. Given the scale of India, successfully implementing it there would be a significant step towards global adoption.
鈥淥ur goal is to provide accessible, scalable tools that help communities to visualise and make informed decisions about flood risks and mitigation strategies,鈥 says Professor Wilson. 鈥淭hrough collaboration and technology, we can make a real difference in addressing one of the most pressing challenges of our time,鈥 he says.
