Gully Density

AUS-AIF-URB-GUL General Moderate confidence

Benchmark Value

10 m/ha
Direction: Lower is desirable ↓
Form: MaximumOnly

Scoring Curve

Scoring curve unavailable

The scoring engine could not generate a curve for this benchmark context. The primary form is Point, but the benchmark data may be missing required fields (e.g., optimal range bounds for an OptimalRange benchmark). This is typically a data quality issue in the benchmark pipeline.

Evidence & Context

A gully density exceeding 10 m/ha (equivalent to 0.1 km/km²) represents a critical transition point.

Metric Definition:

Gully Density is defined as the length of active gullies per unit area, typically expressed in metres per hectare (m/ha).

Benchmark Definition:

This benchmark marks the maximum acceptable gully density in urban areas of Australia's Arid Inland Floodplains & Ephemeral River Systems before severe ecological and economic degradation occurs.

Justification:

This threshold marks the transition to a significantly degraded landscape state with severe ecological and economic consequences.
