Investigation of textural attributes of sediment in Ifelodun County, Nigeria

Abstract

Stream sediments were collected from different areas in Ifelodun county within latitude 8°45¹N to 8°5¹N and longitude 4°46¹E to 5°6¹E. 13 samples of sediments were obtained from each of the eight locations totaling 108. A German standard sieve set of mesh with shaker was used for grain size analysis. The results of grain size analysis range from medium to very coarse sand as the majority of sediment composition before investigation of textural parameters. The result of textural parameters was obtained and used to differentiate the depositional environment of the sediments. The mean, sorting, skewness and kurtosis defined the sediment as very coarse, poorly sorted, vary from very fine skewed to near symmetrical with mesokurtic environment, although the other extreme tails also exist. Positively skewed and poorly sorted sediments characterized low energy environment.
