Grain Size Analysis of Quaternary Sediment from Kendari Basin, Indonesia

Kendari basin is a geomorphological unit, which is bounded by a ridge as the product of tectonic. It can be classified as inter fault-scarp basin. There are 20 samples taken with random sampling method along the watershed Wanggu. Sedimentary samples from Kendari basin are moderately well sorted to poor sorted, dominant coarse skewness to very coarse skewness, and very platycurtic to very leptocurtic. Based on the frequency distribution of the grain size of the sediment, generally samples of sediment from the river order 1 shows the appearance of bimodal. Mean phi shown grain size between coarse to moderatly, Sortation dominant poorly sorted, with skewness negative and kurtosis dominant platycurtic. Multivariate statistical analysis it appears that sediment samples are strongly influenced by the activity of the river.
