To study the variations in beach morphology : A Part from the Book Chapter : Morphological Uniqueness of Beach Sindhudurg District, Maharashtra, India

To study the variations in beach morphology field work was carried out in October-November 1989 after the end of the monsoon season to collect sand samples for textural analysis and chemical analysis. It was found during the study that beach heights varied from 0.3 mts to 1 mt above the level of the intertidal zone. It was also found that even in hand samples most of the beaches had a greater proportion of sand compared to silt and clay. The pH values of the beach sand samples were also determined in the laboratory.

A study was also carried out to find out if there was any relationship between texture and angle of the beach. The gradients of individual beaches were measured with the help of the Abney level and the beach samples were collected from every site, the gradient was measured. Fourteen samples taken from different locations spread all over the shores of the study area. shows the location sites from which beach samples were collected.

Recent Global Research Developments in Beach Morphology in Sindhudurg District, Maharashtra

Study Area:

  • The study focuses on the extreme southern section of the Maharashtra coast.
  • Specifically, it examines the shores of the Sindhudurg district, which extends between 15°45’ N latitude and 16°30’ N latitude.
  • The coastline in this area has a general orientation from north-northwest to south-southeast.
  • The total length of the coastline in the study area is approximately 100 kilometers.

Beach Sediments:

  • Beaches consist of sediments derived from the disintegration of land materials.
  • These sediments include sand and gravel eroded from terrestrial rocks.
  • The composition of beach sediments reflects the nature of the source rocks and can be used to assess relative contributions and transport processes.

Research Methods:

  • The study likely employed various methods, such as grain size analysis and surface texture examination of sand-sized quartz grains.
  • These techniques help understand the energy flux of transporting agents and the depositional environment.
