Description :
The Zohreh River delta is developed since the late-Holocene. The AA. aim to determine the coastal sedimentary processes of this delta and to detect the evolutionary trend of the deltaic plain at the northern Persian Gulf, based on field measurements, numerical modeling, remote sensing and laboratory analyses. The results showed that flash floods and turbidity currents transport sediment to the deltaic area, and tidal currents play an important role in sediment redistribution and in the high diversity of sedimentary facies. Flood plains, tidal flats, crevasse splays, nebka, and sabkha are the most important sedimentary facies in the study area. The rate of long-term progradation of the delta implies an increase of sediment supply from the catchment area due to land use changes and river bank erosion. A key part of this research is presenting the implications of the permanent shoaling trend which is prograding toward the international shipping corridor at the north of the Persian Gulf.
