Abstract：

New　analytical　solutions　of　pore-water　pressure　(PWP)　distributions　in　a　vegetated　multi-layered　slope　are　derived　considering　the　effects　of　roots　on　water　permeability.　PWP　distributions　are　significantly　affected　by　root-induced　reductions　in　water　permeability　due　to　increases　in　the　root　volume　ratio　(Rv).　Under　drying　conditions,　negative　PWP　increases　with　Rv.　The　negative　PWP　induced　by　root　water　uptake　increases　with　the　desaturation　coefficient　(αi)　or　the　ratio　of　the　transpiration　rate　to　saturated　water　permeability　(Tp/ksi).　As　the　overall　water　permeability　underneath　the　vegetation　layer　decreases,　the　negative　PWP　induced　by　root　water　uptake　increases.　©　2018　Elsevier　Ltd
