This contribution presents a project for 3D modelling and analysis of a valley floor for hydrological simulations. An RPAS (Remotely Piloted Aerial System) is used to mount either a high-resolution photogrammetric camera or a thermal infrared camera in two different, consecutive flights recording an image sequence. The images of the photogrammetric camera are used to generate both a digital terrain model and an orthoimage mosaic. The images of the thermal camera are coregistered to this orthoimage. This allows the localization and identification of surface water flow that is not derivable from the terrain model only. The results can be used to improve and evaluate process based hydrological models.     «
