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… 



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.

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. Designed

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.

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 and

A Two–Parameter Model of Snow–Avalanche Motion

Abstract 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

Three-Dimensional Equations for Mass Centre Motion of an Avalanche of Arbitrary Configuration

The path over a surface with complex topography that a snow avalanche will take is usually not known in advance. To predict avalanche paths over such terrain, we propose a model for the motion of the

Flow-R, a model for susceptibility mapping of debris flows and other gravitational hazards at a regional scale

A new spreading algorithm is developed, an improved version of Holmgren's direction algorithm, that is less sensitive to small variations of the DEM and that is avoiding over-channelization, and so produces more realistic extents.
