Scoring Curve

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

Evidence & Context

Given this evidence, a benchmark reference value range of 100 - 1080 mm/hr is proposed for Soil Water Infiltration Rate in Alpine Humus Soils within Australian alpine and subalpine protected natural areas.

Metric Definition:

Soil Water Infiltration Rate (SWIR) is a critical soil physical property that governs the partitioning of precipitation into surface runoff, soil water storage, and groundwater recharge.

Benchmark Definition:

This benchmark defines the typical range of soil water infiltration rates in Alpine Humus Soils of Australian alpine and subalpine protected areas, indicating healthy soil function for water absorption and movement.

Justification:

The benchmark is based on direct, field-based measurements of saturated hydraulic conductivity (Ksat) values for Alpine Humus Soils in the Snowy Mountains, representing a range from functional to optimal health.

Notes

No upper detrimental threshold — higher values are always better up to natural saturation. The range reflects natural variability in Alpine Humus Soils, with the lower end representing highly functional soils and the upper end indicating optimal soil structure and hydrological benefit.
