Sonadia is one of the most important
islands of Bangladesh.
South-eastern shore of the island, which is a growing sand bar, has to
encounter continuous and rapid morphological changes. So study of the sediment
characteristics of this Sand Bar is very important. In the present study, grain size analysis of this Sand Bar
has been done on the basis of laboratory analysis. Sediment samples were collected from 9 (Nine) stations
and texture analysis of sediment was completed following a standard procedure of sieve analysis of sand samples. The
average value of median (MD), mean (M), standard deviation (s), skewness (SK)
and kurtosis (K) of sediment of the Sand Bar of Sonadia Island was 1.93, 1.87,
0.44, 0.11 and 1.88 respectively. Highest median, mean, standard deviation, skewness and kurtosis of Sand Bar of Sonadia
Island was 2.98 (Station 2, Lower Shore), 2.68 (Station 1, Lower Shore), 0.83
(Station 1, Middle Shore and Station 2, Lower Shore), 0.65 (Station 2, Lower
Shore) and 3.59 (Station 1, Lower Shore) respectively. Lowest median, mean, standard
deviation, skewness and kurtosis of Sand Bar of Sonadia Island was 1.42
(Station 9, Middle Shore), 1.45 (Station 9, Middle Shore), 0.30 (Station 5,
Lower Shore and Station 8, Lower Shore), 0.04 (Station 5, Upper Shore) and 0.94 (Station 6, Upper Shore) respectively.
