Resumen:
A mechanism is proposed for the formation of tidal creeks in salt marshes which is exemplified by themarshes of the Rio Gallegos estuary, Argentina. It has been observed that salt pans are elongated in the meanwind direction and are likely to extend by wave erosion ofthe surrounding marshes. Interconnection betweenthe pans leads to growth and interaction with existing creeks and channels. Tidal exchange of the waters thenpromotes further erosion, or subsequently to filling in by the introduced suspended sediment. This mechanismcontrasts with headward erosion by existing creeks.
