Remedial Measures to Combat Sea Erosion Along West Coast of India

TL;DR: In this article, a groin field with six numbers were proposed, and field observations indicate littoral drift is directed towards west direction, and the details of studies and effect of groins were highlighted in the paper.
Abstract: The west coast of India from Kanyakumari (Cape Comorin) to Trivandrum bordering Arabian sea is a thickly populated one. Fishing is the main occupation of the hamlets. The coast is prone to southwest (June–September) and northeast monsoon (October–December) waves in every year. The southwest monsoon is severe along the coast creating heavy erosion resulting loss of valuable lands, roads, worship places and houses. Mandaikadu is one such affected coast located on the west coast of Indian Ocean. Studies in the form of field observations, bathymetry and numerical model studies were carried out. Based on the findings, groin field with six numbers were proposed, and field observations indicate littoral drift is directed towards west direction. The details of studies and effect of groins were highlighted in the paper.

TL;DR: In this paper , the authors proposed an approach to improve the fishing facility harbor at the confluence point of river Tampraparani in Kannyakumari, Tamilnadu.
Abstract: The coastline of Kannyakumari or Cape Comorin (80 4.1’ N 770 33.05’E to 8013.01’N 77014.02’E) bordering Arabian Sea is located southwest of the Indian peninsula. Fishing is the main occupation. During southwest monsoon from June to September, coast experiences high waves. Moreover coast has steep slope resulting in breaking of waves on the coast causing erosion. Because of this fishing operations are almost coming to a halt. This coast of Tamilnadu has its coastline oriented along East-west direction along its west coast bordering Arabian Sea. The coast is dominated by alongshore littoral drift and onshore-offshore transport. Here river Tampraparani confluences with Arabian Sea and to improve fishing facility harbor is proposed at the confluence point. The project was completed in 2013 with slight modifications which has resulted a highly complicated entrance condition. The details of observations, estimation of sediment transport and remedial measures suggested are highlighted in the paper.

TL;DR: Kraus et al. as mentioned in this paper made a numerical simulation of the long-term shoreline evolution of the sandy beach adjacent to Oarai Harbor, Japan and verified the model's predictive capability.
