Soil Water Infiltration Rate

AUS-TGP-LVG-SWI General High confidence

Benchmark Value

10 mm/hr
Thresholds: Lower: 10, Upper: —
Direction: Higher is desirable ↑
Form: LowerThreshold

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 7 benchmarks together — the OptimalRange form drives the primary score, while 6 guard(s) constrain the result.

Evidence & Context

Threshold Value: < 10 mm/hr, with severe dysfunction occurring at ~5 mm/hr.

Metric Definition:

Lower critical threshold for soil water infiltration rate below which soil function is critically impaired.

Benchmark Definition:

The infiltration rate below which soil function is critically impaired and degradation processes accelerate.

Justification:

Supported by quantitative data from NSW Local Land Services and qualitative descriptions of severely degraded woodlands.

Notes

Below this threshold, runoff increases dramatically, initiating erosion and reduced plant growth.
