Abstract
Surface sediment samples from the mangrove forest of Setiu river were analysed for the grain size analysis in order to understand better the accretion processes in the mangrove environment. There is a significant (P<0.05) relationship between sediment characteristics with the seasonal changes with a decreasing mean particle size occurring during monsoon seasons. The accretion rate in this study was determined using 230Thexcess and an average accretion rate of about 0.61 cmyr-1 was obtained. Those fairly high average accretion rates obtained indicating that this mangrove may be still prograding and in an immature stage with an estimated age of 163 years.
Keywords: Mangrove, 230Thexcess sediment characteristic
