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
- Retention, settling and grain-size sorting where river flow meets tides and salinity gradients.
- 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.
