Shield for Sand: An Innovative Barrier for Windblown Sand Mitigation

Background: Windblown sand mitigation for civil structures in arid environment is crucial. Indeed, the number of railways crossing deserts and arid lands is increasing. A number of sand mitigation measures already exist. Among them, sand barriers are particularly intended for line-like infrastructures. We reviewed patented sand barriers on the basis of their shape and porosity. Objective: A new solid barrier for windblown sand mitigation called Shield for Sand is presented. Shield for Sand has been designed with the aim of maximizing the sand trapping efficiency through an upper windward deflector and simplifying its maintenance by complaining to sand removal machines. The development of Shield for Sand follows the path traced by the Technology Readiness
