Obsah:
- <p>Effective flood resilience and climate adaptation strategies depend increasingly on accessible, science-based resources that support both decision makers and educate the general public. This study presents an open-source, interactive online tool for three-dimensional (3D) flood impact visualization, enabling users to explore flood depth and velocity layers, compare future climate and infrastructure scenarios, and assess exposure via a vulnerability index. The tool builds on calibrated and validated 2D HEC-RAS hydrodynamic models, served as tiled imagery overlays via Cesium Ion to ensure smooth, browser-based performance. Benchmarking against conventional 2D geographic information system (GIS) platforms helps optimize usability while maintaining resolution. Existing open-source platforms offer 2D static maps or imagery, whereas a 3D visualization approach better enables spatial context and elevation-aware interpretation of flood impacts, which is particularly valuable in complex urban terrain. The vulnerability index classifies each raster cell into one of four increasing vulnerability levels by combining maximum flood depth and velocity. The platform's architecture is modular and globally scalable, demonstrated here using New York City case studies of Hurricane Sandy (2012) and Hurricane Ida (2021). A key novelty of this real-time, Cesium-based visualization platform is its integration of protective measures, such as sea walls, alongside support for user-uploaded data to better enable dynamic visualization of resiliency efforts and their impacts. Furthermore, the integration of real-time visualization with scalable infrastructure and climate scenario toggles fills a critical gap in current open-source 2D and 3D flood planning tools, which often lack interactivity and scenario adaptability. Co-developed with input from the NYC Mayor’s Office and community stakeholders, the tool was iteratively improved to balance technical utility and intuitive design. By combining hydrodynamic modeling with interactive 3D geovisualization and an inclusive development approach, this platform offers a scalable, open-access solution for communicating, analyzing, and planning for future flood scenarios.</p>
