Interactive comment on “ The Gravitational Process Path ( GPP ) model ( v 1 . 0 ) – a GIS-based simulation framework for gravitational processes

  title={Interactive comment on “ The Gravitational Process Path ( GPP ) model ( v 1 . 0 ) – a GIS-based simulation framework for gravitational processes},
  author={Volker Wichmann},
In his manuscript, V. Wichmann presents a GIS-based simulation framework for gravitational processes, i.e. a compilation of model components and their software implementation. It includes various well-known as well as recently developed approaches that conceptually or semi-physically represent displacement processes (but not initiation processes). This simulation framework can be of great interest and value to a broad range of academic, government and corporate users especially since its… Expand


System for Automated Geoscientific Analyses (SAGA) v. 2.1.4
The wide spectrum of scientific applications of SAGA is highlighted in a review of published studies, with special emphasis on the core application areas digital terrain analysis, geomorphology, soil science, climatology and meteorology, as well as remote sensing. Expand
Simulation of debris flows in the Central Andes based on Open Source GIS: possibilities, limitations, and parameter sensitivity
A GIS-based model framework, designed as a raster module for the Open Source software GRASS, was developed for simulating the mobilization and motion of debris flows triggered by rainfall. DesignedExpand
r.randomwalk v1, a multi-functional conceptual tool for mass movement routing
The key functionalities of r.randomwalk are demonstrated, a flexible and multi-functional open-source tool for backward and forward analyses of mass movement propagation that can be combined with release indicator scores or probabilities, and with exposure indicator scores. Expand
Geomorphic coupling and sediment connectivity in an alpine catchment - exploring sediment cascades using graph theory
Through their relevance for sediment budgets and the sensitivity of geomorphic systems, geomorphic coupling and (sediment) connectivity represent important topics in geomorphology. Since theExpand
A new modelling approach to delineate the spatial extent of alpine sediment cascades : GIS and SDA applications in geomorphology
The delineation of sediment cascades in alpine geosystems requires the identification and localisation of the effective geomorphic processes. In order to classify the terrain on that basis, modellingExpand
Calculating catchment area with divergent flow based on a regular grid
Abstract A new procedure is described for determining the catchment areas for all cells in a regular elevation grid, a problem of fundamental importance in analyzing drainage patterns, mineralExpand
A review of rockfall mechanics and modelling approaches
Models can be useful tools to assess the risk posed by rockfall throughout relatively large mountainous areas (>500 km2), in order to improve protection of endangered residential areas andExpand
Modeling of geomorphic processes in an alpine catchment
Within the SEDAG project the sediment yield of various processes (including soil erosion, rockfall, debris flows, shallow landslides and full-depth avalanches ) is studied in two catchment areas inExpand
A Two–Parameter Model of Snow–Avalanche Motion
Voellmy’s (1955) method for computing the run-out distance of a snow avalanche includes an unsatisfactory feature: the a priori selection of a midslope reference where the avalanche is assumed toExpand
Integrating field measurements, a geomorphological map and stochastic modelling to estimate the spatially distributed rockfall sediment budget of the Upper Kaunertal, Austrian Central Alps
Abstract The estimation of catchment-scale rockfall rates relies on the regionalisation of local measurements. Here, we propose a new framework for such a regionalisation by the example of a caseExpand
