Surface Water Mineralization in Bonoua Region, Côte d'Ivoire, Across Rainy and Dry Seasons

A 2026 study by Privat Tohouri analyzes 28 water samples from rivers and lagoons in Southeastern Côte d'Ivoire's Bonoua region. The dataset, shared on figshare, captures physicochemical parameters, major ions, nutrients, and trace metals from two seasonal sampling campaigns. Results show pronounced seasonal contrasts in mineralization, with electrical conductivity increasing over 100% during the dry season.

Use Cases

• Modeling spatio-seasonal variability of water mineralization based on physicochemical parameters and major ions.
• Assessing water quality using indices like the Modified NSF-WQI based on parameters such as EC, NH₄⁺, and PO₄³⁻.
• Identifying dominant hydrochemical processes and facies shifts using Piper and Gibbs diagrams.
• Analyzing multivariate relationships between mineralization factors, nutrients, and redox-sensitive elements via Principal Component Analysis.

Strengths

• Includes 28 samples with paired seasonal measurements (14 rainy season, 14 dry season).
• Analyzes a range of parameters including physicochemical properties, major ions, nutrients, and trace metals.
• Applies multiple established analytical methods: Piper diagrams, Gibbs diagrams, ionic ratios, PCA, and a Modified NSF-WQI.

Limitations

• Dataset scale is limited to 14.4 KB; the underlying data table structure and row count are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Geographic scope is restricted to a single region in Côte d'Ivoire, limiting generalizability.
