Nowadays, the mapping of sediment distribution are crucial in research as it can be
interpreted into other information and can be used in further study. Study on
bathymetry mapping was conducted at the coral reef area between Pulau Bidong and
Pulau Karah waterway by using Sound Navigation and Ranging (SONAR) technology
which is Multibeam Echo-sounder R2Sonic. The aims of the study was to determine
the sediment size, to obtain the backscatter image and to produce sediment
distribution map by using multibeam technology. Grain size analysis was used to
analyse the ground truth data. Database from multibeam were processed to retrieve
the bathymetry map and backscatter strength by using multiples software. The grain
size analysis results were medium sand, course sand, very course sand and granules.
Results for multibeam, the backscatter strength were range from -67.8002 to -15.201
and the sediment distribution map from integration of both data was obtained.
