Extreme floods, such as the 2021 Central European Floods, can result in large amounts of debris being carried by the water, which can block waterways and worsen flood damage. The buildup of debris can lead to structural damage and bridge failures due to the combined effects of the flood's force and the debris.

A new approach to managing floods involves including debris transport in flood simulations. However, this is challenging because needs to be a comprehensive analytical framework for simulating debris transport exists. We aim to use stochastic methods to determine the timing of large-scale debris accumulation in urban areas. Such methods will greatly improve flood management by assessing and quantifying the inherent risks of these elements in urban floods.

We will use ground and remote sensing data and flood mapping to create maps showing where there is a risk of clogging and reduced water flow capacity in urban areas during flood events.
