Retention, storage and drainage of rainwater in and along forest roads

The aim of this project is to develop a new water drainage system for forest roads based on the principle of retention. Instead of the densest possible surface layers, forest roads are to be constructed with infiltration-capable superstructures, which allows the water to infiltrate the adjoining forest in a delayed and damage-free manner by means of retention and storage. It is intended to reduce the concentrated run off from pipe culverts to such an extent that, if possible, the pipe culverts will no longer be the starting point for debris flows and pluvial floods in the settlement area in the future. Reduced water runoff on the surface of forest roads is also expected to decrease the erosion and reduce damage due to heavy rains. This, in addition to a reduction in required maintenance measures, will also ensure an extension in the life of the forest roads.
