Laboratory of Hydraulics, Hydrology and GlaciologyOpen OpportunitiesDifferent designs of Macro-Roughness Elements (MREs) like boulders, rootstocks, and logjams have been implemented along the Töss River as part of a restoration project. The different designs alter flow velocity fields at different scales, with consequences on flow heterogeneity and local morphology. Field experiments, which started in 2023, quantify these developments using Large Scale Particle Image Velocimetry. (LSPIV). - Water and Sanitary Engineering

| River restoration projects often use macro-roughness elements (MREs) like logjams to ensure flow variability and different riverbed morphologies. In doing so, practitioners aim at increasing habitats and “artificial” refugia for aquatic species. On the other hand, such structures alter flow dynamics and hence sediment transport, making it difficult to predict their development under flood conditions. - Water and Sanitary Engineering

| Ice avalanches are an important mass movement in glacierized mountain areas. In this project, we analyze glacier retreat scenarios until the end of the century with an eye towards future hotspots for ice avalanche activity. To assess the future risks from these processes, we intersect the knowledge about glacier retreat with that on the expected formation of glacial lakes and future infrastructure projects. - Glaciology

| The failure of the Bu Mansour Dam in 2023 produced a flood that was devastating to the city of Derna, Libya. Unfortunately, the failure process and the magnitude of the flood discharge remain uncertain. The purpose of this thesis will be to model a potential dam failure mode, simulate the downstream routing of the resulting flood, and assess the flood intensity in the city. - Water and Sanitary Engineering

| In this Master’s thesis the hydroabrasion resistance of six different invert materials used at the Solis Sediment Bypass Tunnel (SBT) shall be systematically investigated. Based on field inspection data from 2012 to 2025, the study aims to assess abrasion depths, hydraulics and bedload transport rates , to validate a recently developed mechanistic abrasion model. - Water and Sanitary Engineering

| The wide range of restoration measures in channelized, morphologically degraded rivers includes dynamic river widening. This method is based on the reactivation of bank erosion, sediment redistribution, and channel shifting processes within certain spatial limitations. The goal is to restore the morphodynamic processes typical for river-floodplain systems and to increase the diversity of aquatic and terrestrial habitats. - Water and Sanitary Engineering

| Der Tagesspeicher Val d’Ambra ist auf Sedimentablagerung empfindlich. Schwebstoff lagert sich im See und am Einlaufrechen der Fassung ab und führt dort zu Verstopfungen. Jährlich muss die Anlage ausser Betrieb gesetzt werden, um eine mechanische Reinigung des Sees und der Wasserfassung auszuführen. Ziel dieser Arbeit ist es, eine Optimierung der Wasserfassung im Sinne einer Spülmöglichkeit und eines optimierten Unterhalts des Rechens zu entwickeln. - Water and Sanitary Engineering

| Low-level outlets (LLO) are key safety structures of reservoir dams. Recent research at VAW have investigated the influence of hydraulic and geometrical parameters on LLO flow behaviour, but further research is needed to validate the results at prototype scale. The aim of this work is to complement the measurements taken in the LLO of Spitallamm dam, Switzerland, quantitatively evaluating scale effects and contributing to the development of safer design guidelines for LLO. - Water and Sanitary Engineering

| Glaciers worldwide are retreating due to climate change, leading to diverse consequences such as sea level rise, changes in water availability, increased natural hazards, and disruptions to tourism. In the European Alps, glaciers are a key attraction, drawing millions of visitors annually. One of the touristic attractivities of glaciers is their role in skiing. However, climate change in and especially recent extreme negative mass balance years have significantly impacted summer skiing (e.g., Abegg and Mayer, 2023). This MSc project aims to assess the effects of climate change on glacier-based ski resorts across the Alps. Potential study sites include Hintertux, Les Deux Alpes, Saas Fee, and Tignes, though other locations may also be considered. - Glaciology
