Framework and Case Study for Converting Open-Channel Irrigation to Pressurized Pipelines

A structured framework and case study data for modernizing agricultural irrigation from open-channel canals to pressurized pipeline systems. The research, authored by Sana Jina and last updated in April 2026, uses the Letaba irrigation scheme in Limpopo, South Africa, to analyze pipeline layouts, pressure management, and economic feasibility. The 330.8 MB dataset integrates hydraulic modelling, energy analysis, and multi-criteria decision analysis.

Use Cases

• Evaluate pipeline layout alternatives and pipe diameters based on hydraulic modelling scenarios.
• Assess pressure management and energy recovery potential using pressure-reducing valves and pump-as-turbine systems.
• Compare modernization strategies based on technical, economic, and sustainability indicators via multi-criteria decision analysis.
• Estimate capital costs and operational savings for irrigation system conversions based on the incorporated economic assessment.

Strengths

• Dataset size is 330.8 MB, indicating a medium-scale collection of models and analyses.
• Framework is applied to a concrete case study, the Letaba irrigation scheme in Limpopo, South Africa.
• License is CC-BY-4.0, permitting broad sharing and adaptation.
• Analysis integrates multiple methodologies: hydraulic modelling, energy analysis, economic evaluation, and multi-criteria decision analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
