4.5. CONCLUSIONS
The best rated alternative location, with the lowest impact, is Enayam, while the worst rated one, with the highest
impact, is Colachel. Kanyakumari and Manavalakurichi obtained similar intermediate ratings. The Enayam
location has lower environmental impacts than the others with respect to dredging, cultural sites and its low
impact on property due to its low population. Port expansion will not need a wide extra inland area since the
land reclamation area will provide room for port facilities and industries.
The Manavalakurichi location has lower environmental impacts than Kanyakumari with respect to, tourism and
cultural sites and lower environmental impacts. Manavalakurichi has lower environmental impacts than Enayam
with respect to coastline and fishing. This is due to its special configuration whereby the port is not attached to
the coastline and connects inland via a bridge that allows the transport of sediments and therefore has a lower
effect on coastal processes. Its inland population density which could be affected by the expansion of the port is
lower than in Colachel and Kanyakumari.
The Kanyakumari location was better rated in regards to its proximity to the transport network and because the
coastline is more poorly preserved. In any case, a more in-depth weighting of the touristic and cultural factor
would rule out this option.
The Colachel location is the worst rated due to its possible impact on the surrounding beaches, which are in an
suitable state of preservation and where there is fishing. The beach located to the east of the port location would
become a pocket beach, retaining its sand and quality, but would be disconnected from the natural coastal
dynamics. In addition, the port is located right next to the heritage town of Colachel, with a dense population
and therefore with the potential to impact on underground water resources
