Environmental and Water Resources Engineering welcomes guest speaker Chase Dwelle - "Uncertainty and Chaos in Urban Flood Modeling."
Each year floods affect nearly 250 million people, exceed $90 billion in economic losses, and pose public health risks to developed and developing cities. In order to better assess risks, models of flooding that rely on modern information about urban environments are needed. With recent advances in sensing technologies, flood modeling has moved from a data poor to data rich environment, but leveraging this new information for modeling poses challenges for efficient computation of flood events. By leveraging uncertainty quantification through polynomial chaos expansions, this research offers a way to assess risks in a probabilistic manner while still accounting for the physics of the studied environmental system.
