To bring to fruition the capability of nature-based solutions (NBS) in mitigating hydro-meteorological risks (HMRs) and facilitate their widespread uptake require a consolidated knowledge-base related monitoring methods, efficiency, functioning ecosystem services they provide. We attempt fill this knowledge gap by reviewing compiling existing scientific literature on including ground-based measurements (e.g. gauging stations, wireless sensor network) remote sensing observations from...
Shallow landslide initiation typically results from an interplay of dynamic triggering and preparatory conditions along with static predisposition factors. While data-driven methods for assessing susceptibility or establishing rainfall-triggering thresholds are prevalent, integrating spatio-temporal information large-area prediction remains a challenge. The main aim this research is to generate spatial model that operates at daily scale explicitly counteracts potential errors in the...
Abstract. This study investigates rock glacier destabilization based on the results of a unique in situ and remote-sensing-based monitoring network focused kinematics Äußeres Hochebenkar (Austrian Alps). We consolidate, homogenize, extend existing time series to generate comprehensive dataset consisting 14 digital surface models covering 68-year period, as well measurements block displacement since early 1950s. The are derived from historical aerial imagery and, more recently, airborne...
Rising temperatures and drier conditions due to climate change will force Alpine forests towards their ecological limits. For an informed decision on climate-smart tree species composition, we need area-wide information about the current future moisture regime in forest areas. this task, soil-vegetation-atmosphere transport (SVAT) models combination with digital mapping techniques have proven useful tools. However, depending selected algorithm (e.g. random - RF, generalized additive GAM,...
Summary Spatio‐temporal variations of precipitation are presumed to influence the displacement rate slow‐moving deep‐seated landslides by controlling groundwater recharge, pore‐water pressure and shear strength. Phases landslide acceleration responding long‐lasting rainfall snowmelt events occur under site‐ event‐specific time delays. Assessing recharge simultaneous recording in a sufficient spatial temporal resolution is essential deepen understanding mechanisms landslide's deformation...
The combination of climate change and social ecological factors will increase risks societies face from hydrometeorological hazards (HMH). Reducing these is typically achieved through the deployment engineered (or grey) infrastructure but increasingly, nature-based solutions (NBS) are being considered. Most risk assessment frameworks do not allow capturing well role NBS can play in addressing all components risk, i.e., hazard characteristics exposure vulnerability social-ecological systems....
Abstract. Physically based modelling of slope stability on a catchment scale is still challenging task. When applying physically model such (1 : 10 000 to 1 50 000), parameters with high impact the result should be calibrated account for (i) spatial variability parameter values, (ii) shortcomings selected model, (iii) uncertainties laboratory tests and field measurements or (iv) that cannot derived experimentally measured in (e.g. calibration constants). While systematic common task...
Deep-seated gravitational slope deformations (DSGSDs) endanger settlements and infrastructure in mountain areas all over the world. To prevent disastrous events, their activity needs to be continuously monitored. In this paper, movement of Reissenschuh DSGSD Schmirn valley (Tyrol, Austria) is quantified based on point clouds acquired with a Riegl VZ®-6000 long-range laser scanner 2016 2017. Geomorphological features (e.g., block edges, terrain ridges, scarps) travelling top landslide are...
In small Alpine catchments, floods are mostly triggered by surface runoff generation during convective heavy precipitation events. Their magnitude also depends on the antecedent soil moisture content, which was shown in several previous studies. This study aims at understanding (a) sites change their response to rainfall events with high intensity under very moist pre-conditions what extent and (b) site characteristics this on. Therefore, we conducted repeated simulation experiments (40-80...
The Copernicus Sentinel-1 mission provides synthetic aperture radar (SAR) acquisitions over large areas with high temporal and spatial resolution. This new generation of satellites providing open-data products has enhanced the capabilities for continuously studying Earth surface changes. Over past two decades, several studies have demonstrated potential differential interferometry (DInSAR) detecting quantifying land deformation. DInSAR limitations challenges are linked to SAR properties...

Following pre-processing steps including registration ground filtering, buildings segmented extracted from datasets. The roofs,...
Abstract The development of better, more reliable and efficient susceptibility assessments for shallow landslides is becoming increasingly important. Physically based models are well‐suited this, due to their high predictive capability. However, demands large, high‐resolution detailed input datasets make them very time‐consuming costly methods. This study investigates if a spatially transferable model calibration can be created with the use parameter ensembles this alleviate process these To...
In contrast to the complex nature of slope failures, physically-based stability models rely on simplified representations landslide geometry.

Abstract. Terrestrial and airborne 3D imaging sensors are well-suited data acquisition systems for the area-wide monitoring of landslide activity. State-of-the-art surveying techniques, such as terrestrial laser scanning (TLS) photogrammetry based on unmanned aerial vehicle (UAV) imagery or acquisitions have advantages limitations associated with their individual measurement principles. In this study we present an integration approach point clouds derived from these aiming at improving...
The use of nature-based solutions (NbS) to address the risks posed by hydro-meteorological hazards have not yet become part mainstream policy response, and one main reasons cited for this, is lack evidence that they can effectively reduce disaster risk. This paper addresses this issue, providing model-based from five European case studies which demonstrate effectiveness different NbS in reducing magnitude hazard thus risk, present-day possible future climates. In OAL-Austria, a deep-seated...

Abstract. In complex mountainous terrain the mapping efficiency is a crucial factor. Unmanned aerial vehicle (UAV) based laser scanning (ULS) has capability for efficient mapping, as it allows realizing higher flight velocities, flying altitude above ground level (AGL) and larger distances between neighbouring strips, compared to image techniques. However, fully utilising of system in mission planning (especially projects, where occlusions differently inclined surfaces are present) prone...
