Urban 3D visualisation rarely considers integrated data visualisation in disaster management. In general, such methods should incorporate interoperable approaches and data to avoid duplicating efforts and to reduce costs. To achieve such interoperability, it is important to investigate the link between the types of potential hazards and the needs of the appropriate 3D model. Then again, risk communication is one of the key components for managing tsunami risk. 3-D Visualization of the tsunami inundation has paramount potential for being an effective visual risk communication tool. This paper presents the application of the rule-based approach to derive the relation between the hazard type and the level of detail, for 3D dynamic inundation visualization model for tsunami in Fethiye Bay of Turkish Southern Coast. The 3D urban model features (and the spatial resolution) considered in this approach are compliant with the level of detail (LoD) definitions specified in CityGML.
