The Dynamics Characteristics of Soil Water Infiltration and Capillary Rise for Saline–Sodic Soil Mixed with Sediment

Yellow River sediment is the potential resource for saline–sodic soil reclamation. Experiments of one-dimensional columns were conducted to investigate upward and downward water transportation characteristics mixed with different addition (0, 10, 20 kg/m2 in top cm layer). The saturated hydraulic conductivity, ratio macroporosity, cumulative capillary adsorption infiltration rate all increased increase addition. No significant differences detected both initial rise treatments, respectively. average rates showed an increasing trend higher than rates. Philip model seems optimal choice dynamic simulation transportation. results may provide useful information salinization amelioration.
