Motaf-Mond

The geomorphology of the Ra’s-e-Motaf-Mond area is governed by the sediment discharge of Mond River.  The study of Mond Watershed has been presented that every year the river carries about 11,600,000 m3 of sediment on average into the Persian Gulf.  Of this volume, about 12% was estimated to be sand.  Therefore, it was estimated that on average approximately1,390,000 m3 of sand is delivered every year to the littoral system by Mond River.  Most of this sand is subsequently carried towards the south by long shore currents and deposited in Motaf Area. 

A detail examination of sediment samples has been collected along Mond River and along the shoreline south of the river mouth. The focus of this study was to look at variations in percentage riverine vs. marine originated sediment in the samples as well as angular shape of sand grains and the grain size. The results are summarized in Figures 7.1 to 7.3.
