Estimation of Hydraulic Conductivity from Grain Size Distribution: A Case Study of Sediments From Panzara River, Tapi Basin, Northern Maharashtra (India)

The aim of this work was to determine the grain size of the sediments and estimation of hydraulic conductivity. A total 20 sediment samples were collected from 13 different locations from both the bank of Panzara river channel, Dhule district (Maharashtra). Geologically, this region belongs to Deccan Volcanic Province of upper Cretaceous to lower Eocene age. Weight percentage frequencies and cumulative weight percentage frequencies of the sediment samples were computed. The grain size parameters like graphic mean (Mz), graphic standard deviation (ϭ 1), graphic skewness (SK) and graphic kurtosis (KG) were also computed. The coefficient of curvature (Cc), coefficient of uniformity (Cu) and hydraulic conductivity (Hc/K) were also calculated. The grain size results showed that sediments are moderate to poor sorted.
