Which risk increases significantly where transverse dunes migrate onto coastal infrastructure?

💡 Explanation

Increased sand abrasion risk emerges because saltating sand particles gain momentum due to wind; this entrainment mechanism rapidly erodes surfaces. Therefore infrastructures risks structural failure, rather than accretion, because sand saltation is concentrated by dunes.
