Irrawaddy and Salween River Sediment and Flow Data from Myanmar

2017-2019 hydrological measurements capture peak monsoon and dry season conditions for two major Myanmar rivers. The dataset includes suspended sediment concentrations, particulate organic carbon, and particle size distributions collected at various depths and lateral cross-sections. Acoustic Doppler Current Profiler data was used to measure flow velocity and calculate total river discharge.

Use Cases

• Model sediment transport dynamics using suspended sediment concentrations and particle size distributions across seasons.
• Analyze the relationship between particulate organic carbon concentrations and hydrological conditions like discharge.
• Compare flow velocity and discharge patterns between the Irrawaddy and Salween Rivers during monsoon and dry periods.
• Investigate seasonal variability in suspended sediment compositions linked to collected water velocity data.

Strengths

• Data covers two distinct hydrological seasons—peak monsoon and peak dry—across four sampling campaigns from 2017 to 2019.
• Includes multiple measured variables: flow velocity, discharge, suspended sediment concentration, organic carbon, and particle size.
• Measurements were taken at various depths and lateral positions, providing a spatial profile of river conditions.

Limitations

• Limited temporal scope with only four sampling points over three years, not continuous monitoring.
• Geographic coverage is restricted to two specific sites in Myanmar, limiting broader regional analysis.
• Sample size and data volume are unspecified, potentially constraining statistical or machine learning modeling.
