In order to investigate the effect of land reclamation time and soil bulk density on soil hydraulic parameters, a study combined laboratory experiments with theoretical analysis was conducted to examine the changes of soil saturated hydraulic conductivity, soil water characteristic curve, and diffusivity with two different bulk densities of four reclamation soils. Results showed that the land reclamation time had significant effects on soil particle component, soil structure, sodium salt content, and so on. Soil saturated hydraulic conductivity decreased with the increase of land reclamation time, while water-holding capacity and soil moisture diffusivity increased with the increase of land reclamation time. Soil saturated hydraulic conductivity, diffusivity and soil water content under the same suction force decreased with the increase of bulk density. With increasing reclamation time, the influences of soil bulk density change on soil hydraulic parameters became more obvious.
