AB  - Urban flood modelling plays a key role in assessment of flood risk in urbanareas by providing detailed information of the flooding process (e.g. location, depth andvelocity of flooding). Accurate modelling results are the basis of reliable flood risk evaluation.In this paper, modelling of a flood event in a densely urbanized area within thecity of Glasgow is presented. Modelling is performed using a new three-dimensional (3D)flooding model, which is an unstructured mesh, finite element model that solves the NavierStokesequations, and developed based on Fluidity. The terrain data considered comesfrom a 2 m Light Detection and Ranging (LiDAR) Digital Terrain Model (DTM) andaerial imagery. The model is validated with flood inundation area and flow features, andsensitivity analyses are conducted to identify the mesh resolution required for accuracypurposes and the effect of the uncertainty in the inflow discharge. Good agreement hasbeen achieved when comparing the results with those published in other 2D shallow watermodels in ponded areas. However, larger vertical velocity (> 0.2 m/s) and larger differencesbetween the 3D and 2D models can be observed in areas with greater topographicgradients (> 3 %). Finally, performance of the proposed 3D flooding model has been analysed.Through the modelling of a real flooding event this paper helps illustrate the case that 3D modelling techniques are promising to improve accuracy and obtain more detailedinformation related to urban flooding dynamics, which is useful in urban flood controlplanning and risk management. To the best of our knowledge, this is the first paper toapply a 3D unstructured mesh finite-element model (FEM model) to a real urban floodingevent. It highlights some of the differences between the 3D and 2D urban flood modellingresults.
