　　The structure and pore related functions of a tilled soil layer vary dynamically under the impact of wetting and drying(WD)cycles.Our objective in this study is to characterize the variation of soil structure as a function of WD cycles as indicated by bulk density(ρb)and water retention characteristic(WRC).
