Outline of Research at the Start	In this project sediment connectivity as a framework for the analysis of sediment transfer within two large landslides in Japan is evaluated. This evaluation is based on quality-maximized, high-resolution digital elevation models derived from UAV imagery on seasonal scale and from aerial photography on decadal scale. Advanced remote sensing technology is applied and further developed to include large scale geomorphic processes in the analysis. The findings aim to improve predictions of sediment supply from large landslides.
