Soil Water Infiltration Rate

AUS-TGP-CON-SWI General High confidence

Benchmark Value

10 mm/hr

Thresholds: Lower: 10, Upper: —

Direction: Higher is desirable ↑

Form: MinimumOnly

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 3 benchmarks together — the OptimalRange form drives the primary score, while 2 guard(s) constrain the result.

Contributing Benchmarks

OptimalRange Primary Point Guard MinimumOnly Guard

Evidence & Context

A lower critical threshold is proposed at an infiltration rate of ≤10 mm/hr.

Metric Definition:

Lower critical threshold infiltration rate indicating functional collapse of soil water absorption capacity

Benchmark Definition:

The infiltration rate below which the soil is considered functionally collapsed and unable to absorb rainfall effectively.

Justification:

This threshold is based on direct field measurements of cultivated, degraded soils in the target biome.

Notes

Below this threshold, severe ecological consequences occur including accelerated runoff, soil erosion, and loss of productivity. ConsistencyResolver applied 2026-03-23 00:16 UTC: UpperThreshold 10 → (check: MaxBelowPointValue, rationale: Clearing the UpperThreshold field to move the threshold to LowerThreshold, consistent with the ecological meaning and Notes.) ConsistencyResolver applied 2026-03-23 00:16 UTC: LowerThreshold → 10 (check: MaxBelowPointValue, rationale: The Notes state 'Below this threshold, severe ecological consequences occur' and 'A lower critical threshold is proposed at an infiltration rate of ≤10 mm/hr', indicating this is a lower threshold. Moving the value from UpperThreshold to LowerThreshold will auto-correct the form to MinimumOnly, resolving the contradiction.) [Auto-corrected BenchmarkForm: MaximumOnly → MinimumOnly] ConsistencyResolver applied 2026-03-23 00:16 UTC: UpperThreshold 10 → (check: MaxBelowOptimalLow, rationale: Clearing UpperThreshold to null aligns with moving the threshold to LowerThreshold, enabling the form auto-correction from MaximumOnly to MinimumOnly.)
