Estimated Sediment Loads and Gully Runoff for Restoration Effectiveness, 2016-2019

Preliminary estimates of discharge, total suspended sediment, and total nitrogen loads from gully sites in the Great Barrier Reef rangelands. Data were generated from monitoring during three wet seasons spanning June-July 2016 to 2019 as part of the NESP TWQ Project 2.1.4. The Australian Ocean Data Network hosts this dataset, which is intended to be viewed in the context of its parent project on gully remediation.

Use Cases

• Modeling the impact of gully remediation on sediment loads based on estimated discharge and concentration data.
• Assessing changes in water quality over time using flow-weighted annual average mean concentrations (FWAAC).
• Comparing event mean concentrations (EMCs) for individual runoff events at specific sites like Mt Wickham.
• Evaluating the effectiveness of restoration practices on reducing total nitrogen in agricultural runoff.

Strengths

• Data covers three consecutive wet seasons (2016-2017, 2017-2018, 2018-2019), providing a multi-year perspective.
• Methods are explicitly documented, including the use of stage-discharge rating curves and relationships between turbidity and TSS/TN.
• The dataset is part of an ongoing monitoring program (NESP TWQ Project 5.9), suggesting potential for future updates.

Limitations

• The description notes high uncertainty in discharge and load calculations for semi-arid systems, and data collection faced challenges like sensor malfunctions and damage.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
