Abstract:
Study on accretion rate was done on Pulau Layang-layang, Pulau Kambing and
Pulau Che Minah in the Kelantan Delta. They were chosen as sampling areas based on
the density of vegetation. The sediment deposits were collected and accretion markers
made of Perspex were buried on September 2006. Samples were collected based on
transect lines was set-up with 3 m intervals sampling points and transects line was set
up to determine the accretion rate for January and February 2007. Sediment samples
were analyzing for sedimentological characteristic using laser diffractometer (MALVERN
Master Sizer 2000). This study found that the accretion rate for January and February is
significantly different. The average accretion rate for Pulau Che Minah is 1.61 cm m-
1
•
Pulau Layang-layang with 1.29cm m-
1
and Pulau Kambing with 0.44cm m-
1
. For
February, the average accretion rate is 1.11 cm m-
1
, is 0.30cm m-
1
and 1.13cm m-
1
for
Pulau Layang-layang, Pulau Kambing and Pulau Che Minah respectively. Characteristic
of surface sediment at three sampling sites are dominated by fine silt, poorly sorted, with
varied of skewness but very leptokurtic.
