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
- Landward transport and later redistribution of sand during high surf, storm surge and wave runup.
- Drivers
- tides; waves; wind; river flow; storms; reef geometry
- Inputs
- water; sediment; heat; solutes; plankton
- Outputs
- mixing; transport; flushing; erosion/accretion; inundation
- Spatial scales
- estuary → shoreline → reef → nearshore
- Temporal scales
- tidal → seasonal → event
- Validity and limits
- Context-specific; do not extrapolate across habitat, season, elevation, salinity or disturbance state without evidence.
