NAUTICAL BOTTOM DETECTION IN SHALLOW WATER: CASE STUDY PATIMBAN PORT
The nautical bottom is defined as a limit at the bottom of the sea water column that can provide navigational disturbances and damage to the ship's hull. This limit cannot be detected accurately using acoustic method but rather detected using rheological measurements. However, current techno...

| Summary: | The nautical bottom is defined as a limit at the bottom of the sea water column that
can provide navigational disturbances and damage to the ship's hull. This limit
cannot be detected accurately using acoustic method but rather detected using
rheological measurements. However, current technology has not been able to
provide more efficient measurements compared to the acoustic method, specifically
in a large area. This study aims to define the nautical bottom in the Patimban Port
Development Area by by combining data from sediment sampling, measuring
electromechanical methods (free fall cone penetrometer), and measuring acoustic
methods (dual frequency single beam echosounder).The results show that the
nautical bottom in the Patimban waters could be defined by determining the
relationship between yield stress and seabed sediment density. The nautical bottom
in this study area is defined by density values ranging from 1.29 t/m3 to 1.32 t/m3
and yield stress ranging from 0.01 kPa to 0.10 kPa.
