Geomorphological characteristics of Nha Trang bay and adjacent area

Abstract

The bottom topography of Nha Trang bay and adjacent area is very diverse and complex, especially in architecture of terrain morphology. It was partitioned by a system of many large and small islands in Nha Trang bay, and created many features of the terrain types on the surface of the seabed such as: deep creek, valley trough mix between the islands that was favorable condition for the marine transportation. The sediment types were differentiated quite clearly on the surface of the seabed topography from the coarse grain of gravelly sand to mud-clay. Therefore, the geomorphology was also varied. By the traditional research method, the geomorphology was divided into 9 geomorphological units and was shown on an overall picture through three different dynamic zones: two geomorphological units for surf wave zone; five geomorphological units for wave zone of destruction and deformation, and two geomorphological units for offshore wave zone.
