Short summary
This paper describes the erosion processes of a small black marl catchment. It is based on terrestrial laser scanner digital elevation model campaigns. A detailed sediment budget is performed, leading to a seasonal sediment transport pattern described spatially and temporally. The link with precipitation intensities and duration is analysed, leading to a conceptual model of erosion that provides clear input for future research regarding potential impacts of climate change on erosion processes.
