Assessing the sensitivity of pluvial flood modelling to the topographic description of Urban Areas

Abstract

As the effects of climate change continue to unfold, pluvial flooding has become a significant concern. While the development of complex models for simulating pluvial flooding events has advanced, challenges related to input data persist. In this research we want to assess the sensitivity of flood models to the level of detail in the description of the topography at small scales. The case study presented below examines a portion of a neighbourhood in Genoa, where cases of pluvial flooding are frequently reported.
