Urban flooding modelling: role of geometric distortion in scale models and influence of urban forms
Summary
Flood losses are particularly severe in urban environments and urban flood risk is expected to increase during the 21st century due to fast urbanisation and more frequent extreme rainfall events. In response, concepts such as water-sensitive urban design, or the sponge city model are rapidly developing. To guide the design, sizing and implementation of these concepts, accurate risk modelling is required. Data from laboratory experiments is recognized as a valuable complement to field observations for validating flood risk management tools.
In this project, I aim to showcase the scientific added value of laboratory scale modelling for validating urban flood simulations. The project will address a twofold challenge: (i) provide missing and sound laboratory validation of urban flooding at the district level; and (ii) apply the validation procedure and data for guiding flood-resilient urban planning.
