3.2 Marine Data Collection
The marine data collection campaign was carried out for two weeks starting
from 23 May 2014 to 7 June 2014. The bathymetric or hydrographic surveying
work was carried out along the Kuantan coastline covering an area of 250
km2, starting from Beserah to Kampung Alur, that is about 50 km long along
the coastline and 5 km length towards the sea. Bathymetric measurements for
Sungai Kuantan and Sungai Pahang were conducted from the estuary towards
approximately 15 km upstream for both rivers. The current and wave data were
collected using equipment Acoustic Doppler Current Profiler (ADCP) model
AWAC AST (1 MHz and 600 kHz) produced by Nortek AS, Norway in two separate
locations, ADCP A and ADCP B. Refer to Table 1 for the coordinate and the
depth where the instruments were deployed. The measurement of tidal data
is based on mean sea level (MSL), measured at two locations using Aquatec
520P water level logger by Aquatec Group UK. The device is also capable of
measuring and recording temperature and air pressure. In this study, the time
interval of 10 minutes has been configured to allow the instrument to record the
tidal changes. The equipment was mounted on the pole piers under water by
divers at both locations (Table 2). The locations of these equipments are ploted
in Figure 1.
