Heterogeneous Clastic Beach Sediments Behaviour - a Comparative Study of Kaup and Malpe Beach System: a Marine Environment of Udyavarariver Basin, West Coast of India

Balakrishna S Maddodi, H.N. Udayashankara and N. Niveditha

The impact of assorted sediment properties depends on coastal processes which are commonly underestimated due to the exertion in portraying and calculating these natures of deposits. On Careful observations of proceeding in the study area reveals not only is sediment heterogeneity substantiality but also in terms of its effect on coastal processes are pragmatic. In majority of the coasts of India and abroad the heterogeneous sedimentary environment can be appreciated. Using geologic and oceanographic parameter descriptions as a guide, the sediment heterogeneity can be defined which give rapid changing sediment appearances which include mixed grain sizes or types, spatial diversity in sediment properties and bed forms. Foremost heterogeneous environments are - gravel-sand coasts, sorted bed form fields, sand-ridge fields, Chenier’s, Mud transgressed coasts, mixed tidal flats, Graded foreshores and Surf Zones. Sediment heterogeneity in each category can also be tabulated into different statistical ranges. These categories illustrate the a bund ant expected shapes of sediment changeability, which recommend that environmental depictions that simplify complication such as median grain size, which are inadequate to define the influence of coastal sediments. Research carried out on Udyavara River Basin comprises of Kaup and malpe beach sediments show high and Low energy level. This has been discussed on the sediment textural characteristics of the both beaches. To characterise the energy level of beaches the Sediment plays a role of document landform formation. Statistical parameters such as Graphical Mean Grain Size (Mz), Standard Deviation (σ1), Skewness (Sk) and Kurtosis (kG) are the tools to relinquish the aforementioned distress. The mean grain size (Mz) is being used to find out the dominance grain size. Standard deviation (σ1) shows the sorting nature of soil or sediment. Skewness (Sk) measures the costiveness of skewed and also kurtosis (kG) quantifies the sediments nature are mesokurtic to very leptokurtic.
