Form: Point

Scoring Curve

This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.

Evidence & Context

Median turbidity during flood events reached 1000 NTU in Cooper Creek.

Metric Definition:

Median turbidity during flood phase in NTU.

Benchmark Definition:

Notes

High turbidity during flood is not detrimental but a natural ecological driver. No upper detrimental threshold — higher values are always better up to natural saturation.
