Abstract

The laboratory model test was conducted by dividing domestic reclaimed tideland into Sandy Loam (SL) and Silt Clay Loam (SiCL) to estimate soil moisture change and water supply according to soil characteristic when establishing irrigation plan for reclaimed tideland upland crop. In addition, the applicability of each scenario was verified using Van Genuchten model, which is the most widely used mathematical model for analyzing soil moisture characteristics of reclaimed tideland uplands crops. The required water supply according to the target soil moisture tension by reclaimed tideland is as follow. In the case of SL, soil depths of 0~10 cm, 10~20 cm were analyzed as 19 mm, 35 mm to reach the field capacity, and SiCL, 33 mm, 63 mm. The required water supply of SiCL was higher than that of SL. The study compared the simulation results from the scenarios of Van Genuchen model and the measured results from the laboratory model test based on according to the reclaimed tidelands. In the case of parameter, θs, θr, α, η were analyzed 0.55, 0.18, 0.064, 1.74 in SL and 0.46, 0.22, 0.105, 1.92 in SiCL. In terms of soil characteristics, SL with better water permeability was found to have higher applicability than SiCL. By Soil depth, applicability was found in 0~10 cm directly affected by water supply.
