Riverbank Landslides
Slope reduction
The technical dashboard illustrates essential information on the NBS for sustainable river management and on the fundamental actions developed to assess their efficacy and impact. The different sections include: a cartographic interface to track test and monitoring sites, real-time data from sensors, monitoring and modelling results, and a synthetic measure of performance.
The conventional approach to restore bank landslides requires a constant supply of rocks and stones to recreate the original shape of the watercourse and consolidate the banks. The land reclamation consortium estimated that about 37500 tons of such materials are needed yearly, resulting in economic costs, material and soil consumption, carbon dioxide emissions, and simplification of the rural landscape and ecosystem. The proposed solution consists of reshaping the watercourse, giving more space to the water, reducing the slope of the banks and favouring its re-naturalization through local trees and shrubs transplantation
The conventional approach for ordinary maintenance of the river banks as well as of the banks in the dense drainage networks in the basin consists in operating the complete cut of all the vegetation. The proposed solution consists in leaving a strip of uncut vegetation along the foot of the banks. Plant roots are able to consolidate the bank, preventing erosion, and the vegetation increases biodiversity. Maintenance is then carried out in the center of the watercourse channel, preserving regular flow and flood defence, and on the upper part of the bank, guaranteeing safe and smooth maintenance operations.
