Abstract Granulometric studies and depositional pattern of Kolar river stream sediments from Nagpur district, Central India, have been carried out to evaluate its statistical parameters such as mean, standard deviation, skewness and kurtosis. 16 locations were selected for sampling in which 2 samples from each location were collected for accuracy. In a total, 32 sediment samples, which include 6 from tributaries and 26 from the main channel, were collected. Samples were subjected to sieve analysis and results were used for identification of the environment by deposition and grain size parameter calculations. Plots of standard deviation, skewness and graphic mean clearly show that the sediments belong to the river environment. Bivariate plots between the grain-size parameters have been interpreted. Overall, the sediments are characterized by poorly to moderately sorted, very coarse to very finely skewed, platykurtic to leptokurtic but dominantly very leptokurtic sediments. Sorting of sediments from origin to confluence shows a trend from poorly sorted to moderately sorted. The skewness of the samples has a variable range with turbulent energy conditions and a calm and steady energy environment of sedimentation at different locations.
