Grain Size Studies of Coastal Sediments of Visakhapatnam to Bheemunipatnam, East Coast of India – Statistical Approach
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 3
Abstract
The present work aims to address the textural studies of coastal sediments of Visakhapatnam to Bheemunipatnam coast. The textural parameters of beach sub-environments reveals that the sediments are coarse to fine sand, well to moderately well sorted, negatively to positively skewed, meso to leptokurtic in nature. The textural analysis of coastal redsediments reveals that the majority of the sediments are predominantly consists of medium sand, moderately well sorted and positively skewed in nature. The textural parameters of Gosthani estuary sub-environments indicates that the sediments are of medium grain size, moderately well sorted, symmetrical skewed, mesokurtic in nature. C-M diagram shows the most of the foreshore, backshore and Gosthani estuary sediments are deposited by rolling and bottom suspension whereas dune and coastal red sediments are deposited by graded suspension and no rolling.Q-mode factor analysis of grain size data, it is concluded that the sediments of the area are deposited under three different energy conditions. The three factors correspond well with coastal red sediments, beach sediments, Gosthani estuary sediments which corresponds to relatively three different energies of the environments viz., moderate, current energy and medium to low energy environments respectively.
