Groundwater Irrigation Suitability Index for the Collo Plain, Algeria

Thirty groundwater samples from the Collo Plain in northeastern Algeria were analyzed for major physicochemical parameters. The data includes pH values from 6.90 to 7.90 and electrical conductivity from 1356 to 3388 μS/cm, used to compute a weighted Irrigation Water Quality Index (IWQI). Author Faouzi Zahi published the dataset on figshare in May 2026, integrating hydrochemical analysis with GIS and remote sensing.

Use Cases

• Map spatial distribution of irrigation water quality based on the computed IWQI values.
• Identify areas of groundwater degradation for targeted monitoring based on the described northeastern sector near Ouled Mazzouz.
• Support irrigation planning decisions using the provided IWQI classification (good, poor, very poor).
• Evaluate the influence of described factors like paleomarine transgressions and agricultural practices on water quality.

Strengths

• Includes 30 groundwater samples with measured pH and electrical conductivity ranges.
• Provides a computed Irrigation Water Quality Index (IWQI) with values from 35.5 to 87.9 and a mean of 56.8.
• Integrates multiple analysis methods: hydrochemical, GIS, remote sensing, and Analytical Hierarchy Process (AHP).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 5.5 KB, indicating limited scope.
