Gully Density

AUS-TSW-IND-GUL General Moderate confidence

Benchmark Value

0 km/km²
Direction: Lower is desirable ↓
Form: Point

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

The benchmark value for Gully Density in an Optimal state is 0 km/km² of active gullies.

Metric Definition:

Gully Density: The benchmark value for Gully Density in an Optimal state is 0 km/km² of active gullies. An "active gully" is defined as a channel that shows clear signs of recent or ongoing erosion, such as sharp, unvegetated, and unstable headcuts or sidewalls; fresh sediment deposits (splays) at its outlet; or evidence of recent deepening or widening.

Benchmark Definition:

A state of high geomorphic stability and developing ecological function where erosional processes are minimal.

Justification:

Directly derived from a well-documented, quantitatively monitored, and successful leading-practice case study (Ginkgo) that falls squarely within the target biome and land use context.
