Abstract:
Natural morphodynamics of rivers have been altered for centuries through the regulation of their flow regimes. This paradigm in river management has changed over the course of the last few years, and in some cases pioneering regime-based criteria have been applied to partially recover river integrity. One benchmark example is the Spöl River, where a long-term artificial flood program started in 2000 (with the release of 15 high flows during the last 8 years). One of the main purposes of this program was to improve morphological and therefor habitat heterogeneity in the river. After 20 years of the starting of this project, many studies showed that the river recovered part of its mountain river character, and the artificial floods mitigated some of the effects of the river regulation. However, the morphodynamics effects of such effects are still not fully understood and to date there is not a monitoring program for physical processes (e.g., sediment and instream wood transport) in the Spöl available. The aim of this research project is to fill this gap and to improve the understanding of regulated flow effects on river morphodynamics. The better understanding of the fluvial processes occurring in the river (i.e., erosion and deposition of sediment, transport and deposition of wood), will provide an important analytical tool for the SNP and the artificial flood program in particular. Moreover, results will be of interest for the research community in general, as they are expected to improve knowledge about the use of artificial flooding as part of river restoration programs.
