Abstract

Buried perforated corrugated pipes have been proposed as dual-purpose systems for subsurface irrigation and drainage in upland fields. This study evaluated the hydraulic performance of a buried perforated corrugated pipe equipped with a V-shaped impermeable sheet using the HYDRUS-2D model. The pipe was installed at a depth of 45 cm, and soil water movement during irrigation and drainage was simulated under controlled boundary conditions. During irrigation, water supplied through the perforations moved upward and reached soil depths of 35, 30, and 25 cm after approximately 10, 36, and 80 minutes, respectively. The increase in soil water content was greatest near the pipe and gradually decreased toward the soil surface. The V-shaped impermeable sheet effectively reduced downward water loss, promoted upward water movement, and increased the soil water content in the root zone by approximately 3.9% compared with the configuration without the sheet. During drainage, soil water moved efficiently toward the perforated pipe, although the impermeable sheet caused a slight reduction in the drainage rate. Overall, this proposed system effectively enhanced water movement into the root zone while maintaining satisfactory drainage performance. These findings demonstrate the potential of the system as an integrated subsurface water management technology for precision agriculture. The simulation results provide practical information for optimizing pipe design and supporting automated irrigation and drainage management to improve water-use efficiency and crop production in upland fields.
