Kochi is a city in the Indian state of Kerala. Kochi is located in the district of Ernakulam. Old Kochi loosely refers to a group of islands including Willingdon Island, Fort Kochi, Mattancherry and Mundamveli. Today, Kochi includes Ernakulam, old parts of Kochi, Kumbalangi, and outlying islands. For many centuries up to and during the British Raj, the city of Kochi was the seat of the eponymous princely state — the Kingdom of Cochin, which lay between 9.48° and 10.50° latitude and 76.5° and 76.58° E longitude. Location Kochi is located on the southwest coast of India, in the southern state of Kerala. The city lies at the sea mouth of seven major rivers which start from the Western Ghats and travel through Kerala’s midlands, lowlands and coastal areas, to drain out into the Arabian Sea. Earlier, Kochi was used to refer to the region encompassing Mattancherry, Fort Kochi, Mundamveli and Thoppumpadi. Today, Kochi comprises the mainland Ernakulam, old Kochi, Kadavanthra, the suburbs of Edapally and the exurbia of Kalamassery and Kakkanad to the northeast; Tripunithura to the south east; and a group of islands closely scattered in the Vembanad lake. Islands of Kochi Kochi includes an archipelago of various islands, from large to very small. The major islands in Kochi are : Fort Kochi Bolghatty Island Willingdon Island Vypin Ramanthuruthu Vallarpadam Kumbalam Kumbalangi Gundu Island Geographical features Kochi lies at the northern end of a narrow neck of land, about 19 km long and less than 1.6 km wide in many places, and is separated from the mainland by inlets from the Arabian sea and by the estuaries of rivers draining from the Western Ghats. As a result, Kochi is a natural harbour. Much of Kochi lies at the sea level, and the city along with the suburbs span an area of around 440 km². The city has a seacoast of about 30 miles. Willingdon Island is the largest Indian artificial island, created by dredging the Vembanad Lake under the direction of Lord Willingdon. The city has a rich network of backwaters, which has been declared as National Waterways by the Central Government. Soil and rock Kochi's soil consists mainly of recent sediments (Alluvium, Teri’s, Brown sands etc.). Hydromorphic saline soils are also found in the areas surrounding the backwaters. The major rock types are Archaean-basic dykes, Charnockites and Gneisses. Flora Climate Kochi’s climate is generally tropical, with no
