Abstract

India is one of the most disaster-prone countries in the world mainly due to its high geo-climatic conditions and its higher degree of social vulnerability. Concerning socioeconomic and environmental perspectives, flood is one of the most devastating disasters in the coastal regions of Cuddalore in recent years. The main aim of this study is to create a flood vulnerability and livestock production risks hazard map for the coastal district of Cuddalore with the integration of Geographic Information System (GIS), and the Multi-criteria Decision-Making-Analysis (MCDM). The study was carried out in the most flood-prone areas of Cuddalore. Based on the geographical data a Geographical map was prepared with the technical assistance of the Department of Earth Sciences, Annamalai University using Arc GIS software. The details included in the flood hazard map are the rivers entering the Cuddalore district, their route to the draining Bay of Bengal, their longitude latitude on touching the selected block, available lakes, their drainage pattern, and artificial drainage canals passing through the selected blocks. In addition, connecting roads were also marked. The prepared map can be used to forecast the possibility of flood occurrence and formulation of mitigation strategies in the future.

Conclusion

Currently GIS techniques are used to identify the flood-vulnerable areas in the Cudddalore district of Tamil Nadu based on the different environmental parameters such as rainfall, slope, soil, land use/land cover, geomorphology, and drainage density. From the obtained results it was observed that 40% of the areas are highly vulnerable, 30% of areas demarcated as moderately vulnerable, and 30% are low vulnerable areas in the study area. Based on this study it is put forth that the livestock in the low-lying areas suffer to the deep end because of the typographical location. To overcome this misshapen the farmers must be educated on the flood hazard map which would render the required information to prevent monitory loss.
