Hydrodynamics of the Vadose Zone of a Layered Soil Column

Getting into the heart of water movement vadose zone is essential due to direct impact on aquifer recharge, flood hazards, irrigation planning and resources management in general. Since soil profiles nature appear layers, present study accomplishes a deep investigation water’s motion through layers with different hydraulic properties. A series experiments were conducted laboratory where infiltration, tension, moisture conductivity data collected analyzed. In particular, transparent column was filled two soils (loamy sand over sand), TDR probes, along ceramic capsules connected pressure transducers, set column. Using experimental unsaturated modeling, parameters obtained, simulation prediction. An drainage, imbibition, characteristic curves and, general, hydrodynamics has been achieved. The results current suggest method estimate crucial that are involved soil-water interaction have an runoff, horizon saving.
