Pluvial Flash Flood Hazard and Risk Mapping in Croatia: Case Study in the Gospić Catchment

Since the beginning of 21st Century, Europe has been affected by destructive floods. European Union Member States have an obligation to develop flood hazard and risk maps as support Flood Risk Management Plan (FRMP). The main objective this study is propose a methodological framework for assessment pluvial flash floods in Croatia at catchment level, which can be integrated into FRMP. Therefore, methodology based on source–pathway–consequence approach presented, complies with EU Floods Directive. This comprehensive high-resolution open data available States. Three scenarios are defined low, medium, high probability, design storms different durations. proposed consists analysis, vulnerability assessment, analysis. Pluvial hazards analyzed using 2D hydrologic–hydraulic model. GIS analysis identify receptors potentially flooding susceptibility potential damage depth–damage curves. assessed both qualitatively terms levels quantitatively direct damages expressed monetary terms. developed was applied tested case Gospić Croatia, surrounds small rural town frequently
