As part of the NoeSLIDE project, six sites were initially involved in the investigations (see Figure 4). Some of them are examined at irregular intervals without automatic measuring systems, some of them very intensively with their own power and broadband internet connection. Currently 2 of the 6 sites are still being closely monitored, the others have been completed. The six sites, which are spread across the Waidhofen / Ybbs, Amstetten and Scheibbs districts, are:

  • Salcher landslide (ongoing)
    One of the main research site in the NoeSLIDE projects is in Gresten (district Scheibbs). This study site has its own page with detailed information; please refer Salcher Landslide Observatory

  • Hofermühle landslide / mudflow (ongoing)
    The second main investigation site is the Hofermühl landslide in Konradsheim (Waidhofen an der Ybbs district). A separate page is also dedicated to this location, see Hofermühle.

  • Eckerwirt mudflow (completed)
    The Eckerwirt location is only a few hundred meters west of the Hofermühle location in Konradsheim and is very similar to it, but somewhat larger in size. Due to its activity (mudflow) it has already been extensively investigated by the regional Geology Office of Lower Austria, the WLV and the GBA. In order to determine any surface changes, this area was included in the course of the TLS measurements at the Hofermühle.

  • Amtmann rock fall / tipping (completed)
    The Amtmann is an approximately 30m high, free-standing rock formation in the Ybbstal valley and only a few meters from the busy Ofenlochstraße (B31). As a natural monument, the field structure cannot be blown up; it is therefore checked at regular intervals by the Amstetten road construction authority. In order to investigate possible movements of the rock tower (tilting tendencies, vibrations), a wireless sensor node network was installed on the rock. The evaluation of multi-temporal TLS data was, among other things, used to investigate possible fall processes (rockfall) and the formation of gaps.

  • Ofenloch rock fall / rock fall (completed)
    The Ofenlochstraße (B31) between Waidhofen / Ybbs and Opponitz is highly endangered by rock falls. Several technical protective measures have therefore already been installed along this road and are controlled and maintained by the Amstetten road construction authority. In order to be able to determine extensive changes in the corresponding endangered rock faces, a rock face on the right bank of the Ybbs was recorded at regular intervals using TLS as part of the NoeSLIDE project.

  • Brandstatt landslide (-)
    The Brandstatt landslide is a large-scale and deep landslide that is coupled with smaller and more superficial processes. The movement rates are low but have a high damaging effect. The area was therefore i.a. investigated by the GBA on behalf of the regional geology of Lower Austria. In order to investigate superficial changes, the area was recorded using TLS as part of the NoeSLIDE project.
