Coastal Protection

Coastal protection work

a) Objectives

Performance assessment of coastal infrastructure along the Indian coast to assist in the design of environmentally friendly structures for coastal protection

b) Importance of the project on economics and job creation

The components related to shore protection and infrastructure development have various socio-economic benefits. For example, the benefits of shore protection schemes include erosion control, storm protection, protection of income from fisheries (for fisherfolk) and agriculture, income from tourism and recreation, carbon sequestration, etc. These benefits can be quantified, and a benefit-to-cost ratio may be determined for each case. From a detailed benefit-to-cost ratio analysis along the Bay of Bengal, the ratio has varied from 1 in rural, remote areas to 15 in cities. This clearly indicates that for every rupee spent, there can be potential benefits of up to Rs15.

c) Methodology implemented

Performance evaluation(structural, hydrodynamic, geotechnical, ecological and environmental) at potential sites, including KadalurPeriyakuppam
Area drainage studies, including flooding at potential sites
Field testing of innovative materials, designs, strategies etc, for coastal protection
Design for enhanced and sustainable performance of coastal infrastructure
Sustainable utilization of dredge spoil for shoreline evolution study– ecological and physical effects
Assessment and evaluation of siting criteria for coastal infrastructure

d) Outcomes / Deliverables

Involved in oceanographic study, measurement and analysis of the data
