Topography representing digital elevation models (DEMs) are essential inputs for computational models capable of simulating the run-out of flow-like landslides. Yet, DEMs are often subject to error, a fact that is mostly overlooked in landslide modeling. We address this research gap and investigate the impact of topographic uncertainty on landslide-run-out models. In particular, we will describe two different approaches to account for DEM uncertainty, namely unconditional and conditional… 

Emulator-based global sensitivity analysis for flow-like landslide run-out models

Gaussian process emulation is integrated into landslide run-out modeling and applied to the open-source simulation tool r.avaflow to investigate interactions and it is promising to extend the approach for other computationally expensive tasks like uncertainty quantification, model calibration, and smart early warning.

The impact of terrain model source and resolution on snow avalanche modeling

Abstract. Natural hazard models need accurate digital elevation models (DEMs) to simulate mass movements on real-world terrain. A variety of platforms (terrestrial, drones, aerial, satellite) and

Probabilistic prediction of rock avalanche runout using a numerical model

Rock avalanches can be a significant hazard to communities located in mountainous areas. Probabilistic predictions of the 3D impact area of these events are crucial for assessing rock avalanche risk.



DEM uncertainty propagation in rapid flow-like landslide simulations

Catastrophic events, such as landslides, cause loss of life and devastation of economies all over the world. Often rapid flow-like landslides are even more devastating due to their high velocity and

Uncertainty due to DEM error in landslide susceptibility mapping

Terrain attributes such as slope gradient and slope shape, computed from a gridded digital elevation model (DEM), are important input data for landslide susceptibility mapping. Errors in DEM can

Uncertainties associated with digital elevation models for hydrologic applications: a review

Abstract. Digital elevation models (DEMs) represent the topography that drives surface flow and are arguably one of the more important data sources for deriving variables used by numerous hydrologic

Impact of Uncertainty of Floodplain Digital Terrain Model on 1D Hydrodynamic Flow Calculation

Quantifying DEM Uncertainty and its Effect on Topographic Parameters

Digital elevation models (DEMs) are representations of topography with inherent errors that constitute uncertainty. DEM data are often used in analyses without quantifying the effects of these


Snow avalanches can develop a massive destructive power in mountainous regions. An intensive effort has therefore led to the development of simulation tools to quantify their impact and to develop

Techniques for quantifying the accuracy of gridded elevation models and for mapping uncertainty in digital terrain analysis

We first provide a critical review of statistical procedures employed in the literature for testing uncertainty in digital terrain analysis, then focus on several aspects of spatial autocorrelation

Digital elevation model uncertainty and hazard analysis using a geophysical flow model

This paper describes a new methodology to quantify the variation in the output of a computational fluid dynamics model for block and ash flows, when the digital elevation model (DEM) of the terrain
