Abstract:
Long-term monitoring of fluvial morphology and related processes in the Spöl River (Swiss National Park) Natural morphodynamics of rivers and fluvial processes have been altered for centuries, but recently, the paradigm in river management has changed. One benchmark example is the Spöl River, where a long-term artificial flood program started in 2000 to recover part of its mountain river character. After 16 years, many studies showed that the artificial floods mitigated some of the effects of the river regulation. However, the morphodynamics effects of such events are still not fully understood and to date there is not a detailed morphological map of the Spöl available. Moreover, the differences in flow regimes (regulated and more natural) between the upper and the lower (up- and downstream the Ova Spin Reservoir) parts of the river may lead to different morphologies, but this has not been analysed in detailed so far. Other natural processes, such as natural recruitment of instream wood to the river are still limited under the flow regulation. This limitation can be solved partly by adding artificial wood, however, instream wood dynamics in the Spöl has not been analyzed till now and many open questions remain. The aim of this research project is to fill these gaps. To do this unmanned aerial surveys will be carried out to gather hyperspatial and multispectral imagery, which will then allow construction of highaccuracy digital surface models. During the first phase of the project the main fluvial landforms will be identify, classify and map along the Spöl, which will also allow to compare the upper and lower river reaches. The second phase will be focused on analyzing morphological changes after artificial floods, and the third phase will aimed to analyze instream wood dynamics. The expected results will improve the understanding of regulated flow effects on the river morphodynamics and related processes and about the use of unmanned aerial systems to monitor fluvial processes; outcomes will also contribute to the biological and ecological monitoring of the Spöl (e.g., characterizing physical habitats) and will be of interest of other river restoration programs.
