A Season-Wise Geotechnical and Morphological Study of Alteration in Coastal Profile Along the Shores of Puducherry, India
Soil erosion in the coastal area (coastal erosion) is often a crucial issue in geotechnical aspects mainly with regards to the sediment transport phenomena accompanied by turbulent characteristics of breaking sea waves. This study takes into account a stretch of 1 km of coastline along Veerampattinam coastal stretch essentially to examine the erosion and accretion characteristics which would further lead to the estimation of sediment budgeting for the study area. A study of coastal wave dynamics was performed to understand the seasonal variations of the wave characteristics. The changes in the coastal morphology of the area have been studied periodically using a GPS device and this quantifies the volumetric changes in the beach morphology. The net sediment transport rate and also the quantity of the suspended sediments in motion is also estimated. The experimental results which suggest accretion along the southern part of the Veerampattinam breakwater and thereby erosion along the northern part are quite coherent with the practical observations. The study reveals that in the north-easterly monsoon and post-monsoon seasons, the zone of study experiences rampant erosion with around 20,000 m3 of coastal sediment deposition. The study reveals that the phenomena of coastal erosion in the study area can be addressed by a sediment transfer amounting 24,436 m3 of beach sand from the south side to the northern side of the breakwater.
