Abstract:
This study was conducted along the coast of Kerteh, Terengganu. The objectives
of this study are to determine the physical-chemical water parameters which are
temperature, salinity, pH and dissolved oxygen (DO) of the seawaters during
Southwest Monsoon and Northeast Monsoon at Kerteh, Terengganu and to
determine the different between within Southwest Monsoon and Northeast
Monsoon. The study was conducted in two months which were June 2011 and
February 2012. The data collected during high tide and low tide session based on
the tides table. The data were taken at 13 stations. The data were analyzed by
using the MATLAB software version 2008. The result showed that the level of
temperature, salinity, pH and DO of water was affected mainly by the input of
freshwater from Kerteh River and inflow of saltwater from the sea. The saltwater
intrusion into the estuary was prevented by the sufficient movement of the river
runoff causing the freshwater and saltwater to mixed and formed a vertical mixing.
The result also showed that water temperature and salinity during the high tide of
SW monsoon is warmer than the low tide and high tide of NE monsoon. This was
proved that Kerteh influenced by the monsoon climate.
