Habitat and ecology

Ecological role

Supports Atlas reasoning about ecosystem function, dependencies, threats, conservation leverage points and cross-module consequences.

Process and seasonal context

Definition

Downstream transport of suspended and bedload sediment by streams and floods.

Drivers

rainfall; slope; vegetation; soil properties; waves; currents; disturbance

Inputs

rock; soil; sediment; organic matter

Outputs

soil; suspended sediment; deposited sediment; coastal sand

Spatial scales

soil patch → slope → watershed → coast

Temporal scales

event → centuries

Validity and limits

Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
