Sedimentological studies of samples from Famgbe River were carried out with aid of a mechanical sieve method. 10 loose sediment samples collected along the bank of Famgbe River were subjected to granulometric analysis to determine their textural characteristics and depositional processes. Standard sedimentological methods involving sieve analysis were utilized to determine the various size distribution of each sample. This was further subjected to statistical analysis (mean size, sorting, kurtosis, skeweness). Results show that the samples were very coarse to coarse grain in size (-0.77ϕ to 0.77ϕ), poorly to moderately sorted (0.53ϕ-1.48ϕ), nearly symmetrical to positively skewed (-0.01ϕ to 0.25ϕ) and very platykurtic to leptokurtic (0.14ϕ t0 1.4ϕ) with dominantly coarse grained. Most of the samples are moderately sorted, positively skewed and leptokurtic nature of sediments. This suggests that the sediments were transported by saltation and traction and being deposited during a high energy condition in a fluvial environment.
