Abstract A mechanism is proposed for the Formation of tidal creeks in salt marshes which is exemplified by the marshes of the Rio Gallegos estuary, Argentina. It has been observed that salt pans are elongated in the mean wind direction and are likely to extend by wave erosion of the surrounding marshes. Interconnection between the pans leads to growth and interaction with existing creeks and channels. Tidal exchange of the waters then promotes further erosion, or subsequently to filling in by the introduced suspended sediment. This mechanism contrasts with headward erosion by existing creeks.
