Short Summary

This study evaluates a subsurface water management system using a sheet pipe (SPC) enveloped in calcite-reinforced sand, demonstrating improved water flow rates and productivity in rice cultivation compared to traditional methods.

Objective

• To optimize agricultural water usage and mitigate excess runoff and soil saturation through the implementation of a subsurface irrigation and drainage system using sheet pipes.

Study Configuration

• Spatial Scale: Agricultural farmlands (specifically narrow or hard-to-access areas).
• Temporal Scale: Short-term flow capacity tests (seconds) and crop cultivation cycles.

Methodology and Data

• Models used: Comparative flow capacity tests and agricultural productivity experiments with eight rice varieties.
• Data sources: Experimental measurements of discharge accumulation and water productivity metrics.

Main Results

• Flow Efficiency: The sheet-pipe (SPC) system with calcite-reinforced sand achieved a discharge of 12,000 g in 90 s, outperforming the perforated PVC pipe (PP-C) which took 100 s, and exceeding the performance of geotextile-covered alternatives.
• Water Productivity: In rice cultivation trials, the average water productivity based on evapotranspiration was 1.4 kg·m⁻³, while productivity based on total water input was 0.1 kg·m⁻³.

Contributions

• Introduces a scalable subsurface irrigation solution using calcite-reinforced sand that enhances water flow efficiency over traditional geotextile covers, providing a sustainable management option for constrained agricultural environments.
