Abstract EN

This study was conducted to assess the influences of soil surface conditions and initial soil water content on water movement in unsaturated sodic soils of reclaimed coastal areas.

Data was collected from column experiments in which two soils from a Chinese coastal area reclaimed in 2007 (Soil A, saline) and 1960 (Soil B, nonsaline) were used, with bulk densities of 1.4 or 1.5 g/cm3.

A 1D-infiltration model was created using a finite difference method and its sensitivity to hydraulic related parameters was tested.

The model well simulated the measured data.

The results revealed that soil compaction notably affected the water retention of both soils.

Model simulations showed that increasing the ponded water depth had little effect on the infiltration process, since the increases in cumulative infiltration and wetting front advancement rate were small.

However, the wetting front advancement rate increased and the cumulative infiltration decreased to a greater extent when θ 0 was increased.

Soil physical quality was described better by the S parameter than by the saturated hydraulic conductivity since the latter was also affected by the physical chemical effects on clay swelling occurring in the presence of different levels of electrolytes in the soil solutions of the two soils.
