Modelling runoff generation in high-elevation Alpine catchments requires detailed knowledge on the spatio-temporal distribution of snow storage. With Sentinel-2 MultiSpectral Instrument (MSI), it is possible to map snow cover with a high temporal and spatial resolution. In contrast to the coarse MODIS data, Sentinel-2 MSI enables the investigation...

Satellite-based long-term observations of vegetation cover development in combination with recent in-situ observations provide a basis to better understand the spatio-temporal changes of vegetation patterns, their sensitivity to climate drivers and thus climatic impact on proglacial landscape development. In this study we combined field investigati...

Since the end of the Little Ice Age (LIA), formerly glaciated areas have undergone considerable changes in their morphodynamics due to external forces and system-internal dynamics. Using multi-temporal high-resolution digital elevation models (DEMs) from different remote sensing techniques such as historical digital aerial images and light detectio...
Article
In this paper, the hydrological impacts of future socio-economic and climatic development are assessed for a regional-scale Alpine catchment (Brixental, Tyrol, Austria). Therefore, coupled storylines of future land use and climate scenarios were developed in a transdisciplinary stakeholder process by means of questionnaire analyses and interviews w...

The Chair of Hydrology and River Basin Management of the Technical University of Munich (TUM) investigates within the SEHAG (Sensitivity of high Alpine geosystems to climate change since 1850) project changes occurred in the hydrosphere between 1850 and 2021 and how they are connected with the behavior of the different components of the high Alpine geosystem. Four objectives will be accomplished during the first three years of the project: Analyzing changes in the frequency and magnitude of modelled and observed hydrological extreme events (e.g., floods, droughts, extreme melting events driven by heatwaves, occurrence of rain on snow events and convective storms) in the three study areas eventually occurred in the timeframes 1850-1920, 1920-1980 and 1980-2021. Reducing uncertainty in hydrological model results in high elevation Alpine catchments constraining physically based models with highly resolved meteorological data, remote sensing data (e.g., glacier extension, snow cover), soil properties information (e.g., soil texture, permafrost and vegetation cover) and additional measurements such as streamflow water temperature and electrical conductivity. This objective will be achieved considering the data collected during the monitoring campaigns performed in the current research project (2019 - 2024) and therefore will be tested during both the first and the second phase of the project. Calibrating and validating a physically based hydrological model, describing with particular accuracy runoff generation caused by snow, glacier and permafrost melting processes. Particular emphasis will be given in elevation (and hence temperature) dependent processes. Moreover, the model will be developed also in the second phase (2022 - 2024) of the project to include temperature transport in the river network. Identifying the influences of climate, glacier and snow dynamics, geomorphologic changes as well as land cover changes to the hydrological response of Alpine catchments using calibrated models of different complexity (according to data availability) for the time frames 1850-1920, 1920-1980 and 1980-2021.
