چکیده

Bottom sediment samples from Pahang riverestuary were analyzed for the sediment characteristics in order to understand better sedimentation processes in the estuary. The mean, sorting, skewness and kurtosis values of each sample were determined by the Moment’s method. This study showed that the sediment characteristics were not significantly differ (p > 0.05) with the seasonal changes, except for sorting (p < 0.05). The sediment mean size becomes finer towards the estuarine area with the range of very coarse sand to fine silt. This indicates that the characteristics of deposited sediments at each station are much dependant upon the combination of physical forces such as freshwater run-off, tidal currents and waves.

The temporal variation of organic carbon during the pre-monsoon and post-monsoon seasons in Pahang River-estuary, Pahang, Malaysia

The percentage of organic carbon contents of 62 bottom sediments in Pahang riverestuary were analyzed using the wet dichromate oxidation method. The sediments particle sizes at the same stations were also measured using the dry sieving and laser diffraction methods. In this study, the concentrations of organic carbon are relatively higher during pre-monsoon season and become much lower during t...

Physico-chemical Characteristics and Dissolved Trace Metals in the Pahang River Estuary, Malaysia

Water samples from Pahang River estuary were analysed for Cu, Pb, Zn and Cd at 63 stations during the monson and non-monsoon seasons. Concentrations ranges of dissolved metals in the Chukai estuary were relatively low compared with other estuaries and are not significantly influenced by seasonal changes. Concentration of Cu in both monsoons ranged from 0.57 – 1.01 μgl-1, Pb ranged 0.88 – 1.34 μ...
