Water Quality Monitoring for Gully Remediation Sites in GBR Rangelands, 2016-2019

Australian gully remediation sites in the Great Barrier Reef rangelands contain water quality data collected over three wet seasons from 2016 to 2019. The dataset includes telemetered measurements of rainfall, stage height, turbidity, water temperature, and laboratory analyses of nutrients and total suspended solids. Data were collected by CSIRO as part of the NESP TWQ 2.1.4 project.

Use Cases

• Modeling sediment transport dynamics based on high-frequency turbidity and stage height time-series data.
• Analyzing the impact of gully remediation on nutrient loads using total nitrogen and phosphorus measurements.
• Correlating rainfall events with water quality parameter changes across multiple seasons.
• Studying particle size distribution in runoff using the sub-set of samples analyzed with laser diffraction.

Strengths

• Data covers three consecutive wet seasons (2016-2017, 2017-2018, 2018-2019), providing multi-year temporal context.
• Includes high-frequency, telemetered sensor data recorded at 1-minute intervals during runoff events.
• Laboratory analysis covers a full suite of nutrients including total nitrogen, total dissolved nitrogen, NH3, NOx, total phosphorus, total dissolved phosphorus, and FRP.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Some samples were only analyzed for TSS if not collected within 24 hours, potentially creating gaps in the nutrient data.
