The textural variations were studied through laboratory testing of the samples collected. The samples were first dried for about a fortnight. When they were completely dry, each sample was first measured and was then mechanically analysed for textural class grouping by sieving and sorting method. The textural classes that are identified are coarse sand, find sand and silt and clay.
The results of the textural analysis of the 14 samples are tabulated and grouped area wise as shown in Percentagewise textural distribution of the sample are also shown in the table.

Recent Global Research Developments in Sindhudurg Beach Morphology, Maharashtra.
Seasonal Variation in Textural Characteristics of Beach Sediments:
- A study by Kamble et al.[1] investigated sediment textural parameters along the Mithmumbri and Talashi coastal areas in Sindhudurg.
- The study divided the area into two sectors: erosional (Sector I) and depositional (Sector II).
- During pre-monsoon, sediments were fine to medium-grained, well-sorted to moderately sorted, and skewed.
- Post-monsoon conditions indicated medium to fine sand, signifying high energy.
- Achra, Vayagani, Tondavali, and Talashi beaches showed well-sorted sediments due to wave energy.
- Sector I’s foreshore zone experienced consistent beach erosion at various coasts.
- Linear Discriminant Function (LDF) suggested a shallow marine environment for both seasons.
Monsoon-Impacted Magnetic and Geomorphological Changes:
- The Redi beach in Sindhudurg was studied for morphological and magnetic mineralogical changes related to precipitation [2].
- Annual and seasonal data helped decipher erosive/accretion patterns in beach sediments.
Beach Morphology Study in Sindhudurg District:
- Researchers investigated beach morphology in the southern section of Maharashtra’s coastline [3].
- The study focused on extreme southern areas near the Goa border.
Sediment Textural Characteristics:
- Another study explored sediment textural characteristics using parameters like Graphical Mean Grain Size (Mz), Standard Deviation (σ1), Skewness (Sk), and Kurtosis (kG) [4].
- These parameters help understand sedimentary environments influenced by erosional and depositional agents.
