Abstract: Research project FloRiCiMo aims to couple semantic digital city models with hydronumeric models for the simulation of river floods in urban areas. Despite containing large volumes of data that can be used in the simulation of physical processes (terrain elevation; flow obstacles like houses, bridges or culverts etc. ) and for risk analysis (damage potential evaluation), digital city models have mainly been used for visualization purposes so far. In order to allow for city-model-based flood simulations, this research project addresses issues such as the semi-automated fixing of geometric imperfections, web-based queries for user-defined data extraction, and data transformation for the generation hydronumeric models. 2D (floodplain scale) and 3D (local scale) numerical simulations are then performed based on the data extracted from the city model, and results are imported back and post-processed in the digital city model for visualization purposes. Linking semantic 3D city models with hydrodynamic modules offers numerous advantages in the management of river floods in urban areas, including centralized data management, enhanced communication and easy inspection of simulation results, to name but a few. This paper presents the basic idea, methodical concepts and the results of the first phase of the project
