Based on COMSOL (35), two dimensional transient cross sectional models were used to investigate water and solute transport in the soil column coupled with variable sand column forms, with “a” denoting no sand column, “b” with one vertical middle sand column, “c” with one long slanged sand column, “d” with two long slanged X shaped sand columns. The results showed that sand column obviously increased the transport efficiency of water and salt, which may attribute to the higher hydraulic conductivity and higher diffusion coefficients in sand columns than clay loam coastal saline. The efficiency of sand column depends on its position and its angle accordingly. The slanted columns were overall superior to the vertical ones in transport efficiency. Generally, “d” is the best type, “c” is the second best and “b” is the third, according to the efficiency of salt leaching and the efficiency of the utilization of water resources.
