- Abstract
The article presents a numerical modeling study which evaluates the magnitude that soil moisture hysteresis and infiltration volume affects the function of capillary barriers. It mentions that HYDRUS-1D was used in the capillary barrier system simulation under infiltration conditions for the three configurations of the capillary barriers including fine sand over medium sand (FM), medium sand over gravelly sand (MG), and fine sand over gravelly sand (FG). The study reveals that the hysteresis effect is infiltration-evaporation dependent and has different volumetric water content with that of hysteretic and non-hysteretic models. It concludes that the inclusion of numerically modeled soil moisture hysteresis is essential for practicable engineering designs with problems in barrier leakage.
