Water Turbidity

AUS-TMS-AGR-WTU General Moderate confidence

Benchmark Value

No specific value — see range
Range: 0 to 5 NTU
Optimal Range: 0 to 5
Direction: Lower is desirable ↓
Form: OptimalRange

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.

Evidence & Context

Proposed Benchmark for High Environmental Health (Low Flow Conditions): Dry Season / Baseflow: < 5 NTU. Wet Season Baseflow / Recessional Flow: < 10 NTU.

Metric Definition:

Water turbidity measured in Nephelometric Turbidity Units (NTU), indicating the clarity or cloudiness of water due to suspended particles.

Benchmark Definition:

Water turbidity as a measure of suspended and colloidal matter affecting water clarity in tropical monsoonal savannas under agricultural crop production during dry season baseflow conditions.

Justification:

Derived from data in minimally disturbed tropical savanna catchments and existing horticultural areas under management, supported by regional water quality objectives.
