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.

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.

• Use Rockfor^NET

Rockyfor3D (developed by Luuk Dorren, with support from, amongst others, Frédéric Berger and Franck Bourier IRSTEA Grenoble) is a Windows application that explcitly 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. Rockyfor3D is continuously developed further on the basis of new scientific findings and experiences from the practice. Currently, we are working on new rockfall rebound algorithms and we try to integrate the effect of obliquely felled trees in the model.

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 during a rebound on the slope or during a tree impact

Slidefor^NET is an online tool that estimates the degree of protection of a forest regarding shallow landsliding given the defined slope and forest conditions. It is based on a slope stability analysis that accounts for lateral reinforcement of tree roots.

• Use Slidefor^NET

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
