Hydrodynamic Floodplain Modeling Based on High-resolution Lidar Measurements

Exploiting high-resolution measurements from Laser induced Detection and Ranging (LiDAR) for floodplain modeling is a current challenge for research in hydrodynamics. This challenge aims to improve efficiency in finite element mesh generation and consistency of simulations results. This concept reduces huge LiDAR data sets based on slope classification, routinely deriving case specific, adaptive surface meshes for hydrodynamic simulations and provides a mean for fast data exploitation. Applications of computational fluid dynamics commonly recognize, that mesh resolution is the only unbounded parameter value where specific boundaries and error bands have not yet been considered up to now [8]. Providing this model concept seeks stimulation for further efforts in that particular field of hydrodynamic mesh generation.
