Water Turbidity
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 6 benchmarks together — the OptimalRange form drives the primary score, while 5 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
This benchmark represents the annual median turbidity range observed in estuaries of the Australian Wet Tropics graded as having "Very Good" ecological condition, including those with significant urban development (e.g., Trinity Inlet).
Water Turbidity measured in Nephelometric Turbidity Units (NTU) as an indicator of water clarity and ecological health in tropical marine estuaries.
Annual median turbidity range in NTU representing 'Very Good' ecological condition in tropical marine estuaries.
Derived from the Wet Tropics Healthy Waterways Report Card 2022-23, representing the highest achievable ecological health in urban-influenced estuaries.
