Bankfor^NET is an online tool that simulates hydraulic streambank erosion that can be expected in relation to the channel morphology, bank material, vegetation roots and the discharge scenario. It is a is a one-dimensional, probabilistic model which applies randomness to the soil erosion parameters. The model uses an empirical excess shear stress equation, where the effects of roots are implemented by adapting the material dependent critical shear stress to consider the spatio-temporal distribution of root area ratio (RAR), the dynamics of channel geometry, and stream discharge (cf. Gasser et al., 2020). This tool aims to support experts in the quantification of bank erosion hazards and the effects of biological measures.

FINT (Find INdividual Trees) is an application software for Windows for detecting individual trees on the basis of a detailed surface model (such as those created on the basis of aerial or terrestrial laserscanning data). FINT delivers postitions of dominant trees, tree heights and tree diameters.The user manual can be found here. A Python code, based on the algorithms of FINT and developed respectively improved within the framework of the Swiss research project FINT-CH, can be freely obtained from this download page.

RockavELA is a rock avalanche runout modelling tool which is based on a trajectory specific energy line angle (ELA). For each trajectory the ELA is adjusted for the normalised area under the trajectory profile. More details on the usage and background of the model will follow in the course of 2023. RockavELA can be used for free and can be downloaded here: default RockavELA_install(11.33 MB)

Rockfor^NET is an online tool that estimates the degree of protection of a forest regarding rockfall given the defined conditions. Secondly, it provides the optimal characteristics of a rockfall protection forest given those conditions.

RockFreq is an online tool to derive release scenarios of rockfall events and block volumes for given return periods. The scenarios are calculated using a power-law model which parameters are estimated based on the structure of a rock face and data on block volumes deposited downslope. The manual can be found here:  pdf RockFreq v1.0 Manual (EN)(1.79 MB) .

Rockyfor3D (developed by Luuk Dorren, with support from, amongst others, Frédéric Berger, Christoph Schaller, Nicolas Zuanon and Franck Bourrier) is a software that explicitly and realistically integrates the barrier effect of trees on falling rocks. The model is a spatially distributed, probabilistic, process-based model and uses a Digital Elevation Model for the representation of the terrain and raster maps for the input parameters.

The main calculations carried out by Rockyfor3D are:

• the 3D trajectory of each simulated rock
• the translational and rotational velocity along its trajectory
• the energy loss and transfers during a rebound on the slope or during a tree or net impact

SlideForce (bèta version 0.7) is a spatially-explicit model for the simulation of the runout of shallow landslides and resulting hillslope debris flows. The basis for this model stems from Flow-R (Horton et al., 2013) and has been further developed within a scientific project financed by the Swiss federal office for the environment FOEN, carried out by the Bern University of Applied Sciences – HAFL (cf. pdf SlideForce Project report(98.31 MB) ; report in French with summaries in English and German).

SlideforNET is a web application designed for field assessment of rainfall-induced shallow landslide probability in vegetated slopes. Specifically, this tool is designed to quickly quantify the stabilizing effects of different types of vegetation through the basal and lateral root reinforcement. The user manual can be dowwnloaded here: pdf SlideforNET User Manual(10.07 MB) .

SlideforMAP (bèta version) is a probabilistic model to assess shallow landslide probability on a regional scale with an explicit focus on vegetation scenarios. SlideforMAP uses a finite slope stability calculation that includes the role of root reinforcement both lateral and basal, and soil compression at the toe. SlideforMAP generates a large number of randomly positioned landslides on the raster with randomly generated soil properties, soil thickness, and landslide area to compute the probability of failure at the regional scale. Root reinforcement can be taken into account by either using single-tree detection data available for 10 different tree species, or a land-use raster.

SOSlope is a hydro-mechanical model of slope stability that computes the factor of safety on a hillslope discretized into a two-dimensional array of blocks connected by bonds. Bonds between adjacent blocks represent mechanical forces acting across the blocks due to roots and soil (cf. Cohen and Schwarz, 2017).

The main calculations carried out by SOSlope are:

• the displacement in meters of each cell of the input terrain model
• the factor of safety of each cell
• the location, the number of failed cells, the area and the volume of each landslide
• the mobilised root reinforcement under tension and compression
