First preparations for UAV surveys

First preparations for UAV surveys

Clemens started to mount the first ground control points (GCPs) for the coming UAV surveys. Still the glacier fore-field was almost covered by snow. Anyway, big boulders estimated not to move have been the targets of this sunny day.

The PhD student Clemens Hiller presented the ongoing project work and first results at the session Evolution of glacial-periglacial-paraglacial landscapes and debris-covered glaciers of the General Assembly of the European Geoscience Union. His Poster can be visited here.

Installation of discharge station

Installation of discharge station

Lucky us the locals from Galtür came forward to install our discharge sensor after winter-break. Because of lockdown in Austria and Paznaun valley in particular, we had no chance to reach the field site from Innsbruck. Nice to have a transdisciplinary project! Thanks again to Gottlieb Lorenz (Jamtalhütte), Otmar Hauser (Illwerke VKW) and Martin Walter (municipal Galtür)!      

Final field work 2019

Final field work 2019

Winter is getting closer and almost base flow conditions can be assumed. In general, a low water level is required to survey the cross section of the channel at runoff gauges. However, like observed in many other Alpine catchments this year, discharge remained relatively high in contrast to average fall conditions. Nevertheless we used one of the last snow-free days in the Jamtal catchment to make a photogrammetric survey of the entire channel section next to our discharge radar. In…

Workshop on rockfall in periglacial areas

Workshop on rockfall in periglacial areas

The ARGE Alp Workshop – “Felsstürze am Gletscherrand – Einflussfaktoren | Auslösemechanismen | Schlussfolgerungen für die Praxis” took place in the beautiful mountain scene of Hohe Tauern at the Mountain Hotel Rudolfshütte on 18 – 19 September. Experts from Geology, Geomorphology, Hydrology and Glaciology shared their experience, research and practice on increasing number of rockfall events from mountain faces next to glaciers.  In addition to the presentation of progress and results from the ÖAW/ESS project GlacierRocks, the excursion to the…

Field site visit with project partners

Field site visit with project partners

Again we went out to Jamtal for runoff measurements and survey of the Jamtalferner glacial and paraglacial area. This time the project partners Gabi Schwaizer (ENVEO) and Severin Hohensinner (BOKU) joined the field trip. We used the time to arrange data exchange of remotely sensed information for the analysis of historic evolution of the stream morphology and defined the areas and periods for analysis of the debris-cover on the glacier.   Deep chanels in the sediments recently uncovered from the ice…

Hidden.ice presented @International Mountain Conference

Hidden.ice presented @International Mountain Conference

On 08-12 September 2019 the International Mountain Conference took place in Innsbruck. Within an expert workshop on “Natural hazards assessment – potential, limits and uncertainties of process models and interactions of processes with protection structures and buildings” the motivation of the Hidden.ice project was presented and highly dynamic processes tackled by the project have been discussed. The poster could be visited all over the four days at the exibition area outdoor .

Terrestrial laser scanning @Jamtalferner

Terrestrial laser scanning @Jamtalferner

Just a few days after the helicopter based ALS aquisition stable rock areas have been recorded a second time in cooperation with the project partners of  KU Eichstätt. The TLS data will help to minimize location errors of the final point cloud and increase overall point density for surface analysis of the study area. During the day glacier melt runoff increased markedly and river crossings have been unavoidable. Later the field team got company by cows showing high interest for…

Survey of glacier forefield and first look on runoff data

Survey of glacier forefield and first look on runoff data

On 9 August the first airborne laser scanning survey was performed using a scanning system mounted to a helicopter. The same day fixed position points were established for the upcoming surveys of the glacier tongue and the glacier forefield at Jamtalferner. The first look on the runoff data shows a number of high runoff situations caused by heavy rainfall in addition to glacier melt, but not reaching the peak runoff caused by strong snow melt conditions right after installation of…

Successful installation of runoff measurement

Successful installation of runoff measurement

We joined the installation of the new runoff measurments at Jambach in the Silvretta mountain range with the first meeting of the project’s stakeholders. A fruitfull discussion evolved about challanges and management of the debris load transported towards the water intake downstream. Thanks to all helping hands and cooperations arranged!
