Project summary
The stretch of the River Ripoll in which the project is located, is bounded longitudinally by longitudinal structures (walls and breakwaters) amending river morphology and determine the formation of river banks. The river also has transversal structures. The existing vegetation does not correspond to the potential vegetation due to the high population pressure on land that has suffered over time. There is an important agricultural pressure and few spaces are not occupied by gardens.
The main objectives of this project are: remove the set up gardens in the area of the project; restore the original profile of the channel prior to the installation of the orchards; minimize the impact caused by waste, trash and debris; eliminate the presence of alien species; recovery hydrological, landscape and ecology of the river; encourage the stabilization and protection of river banks against erosion; enhancing the role of River Biological Corridor; inform the public about the river area as well as the objectives and work involved in the project.
