Bangalore is the third most populated city and capital of the Indian state of Karnataka. It is called the Silicon City, the Garden City, the IT Hub, the Pub City of the Nation and with many such nicknames. Bangalore is positioned in the south east of the Deccan plateau (which lies in the center of Mysore Plateau).
Population of Bangalore
This capital covers an area of 1741 square kilometer at an elevation of 3020 feet to be found at 12.97°N 77.56°E on the globe. 8.5 million multi-cultural people, reside in Bangalore. Annual growth of Bangalore is 2.69 %and the population density is calculated as 8,367 per kilometer square. Bangalore is divided into two major segments called the Urban Bangalore
and the Rural Bangalore. Many new districts have been carved out of
these two segments. Most of the people live in the urban segment and the
others are a part of the rural Bengaluru.
Temperature/ Climate of Bangalore
Because of the elevation, the city’s temperature remains to be cool, moderate and pleasant all throughout the year. The Tropical Savanna Climate doesn’t let the temperature drop below eleven degrees in winters and till now; the maximum recorded temperature is 38.9 degrees. Usually the weather maintains itself between 20 degrees to 36 degrees. The silicon city of India gets about 970mm of rainfall per year and thunderstorms are very common in Bangalore. One of the wettest months recorded in Bangalore was the October of 2005.
Topography of Bangalore
The groundwater lies in silty (between sand and clay) to sandy (rock & mineral) layers. The soil on this land is the red soil and the red laterite.This ranges from loamy to clays type of soil.
The city has two main topological terrains-the North (leveled plateau) & the South Taluks (uneven landscape). These Taluks, from the middle of which, a famous ridge passes through the North-Northeast to South-Southwest have slopes and valleys around them. Rainfall on the ridge divides itself in the three valley system & .Doddabettahali is the highest point on the ridge.
The founder of the state- Kempe Gowda-I constructed many water bodies such as lakes so that the city gets access to the water supply. The Diwan of Mysore in 1926-Mirza Ismail specially made the Nandi Hills Waterworks for the same purpose. Kempambudhi Kere was one of the most prominent lakes of Bangalore; however, it vanished with the modern development.
Bangalore has not been affected by any major earthquakes only mild tremors have been noticed. This is because of the flat, plateau location of the Silicon Valley.
Rivers in Bangalore
Kaveri River supplies 4/5th of the total amount of water in Bangalore, rest of which comes from the reservoirs on Arkhawati River. 211 million of US gallons of water are supplied in the city making it the highest, as compared to any other national state capital. However, in years of low rainfall the garden city does face cases of water shortages.
Some of the most prominent lakes of the city are Sankey Tank, Madivala tank, Hebbal lake and Ulsoor lake. There are no major rivers which flow through the garden city of India but in the proximity of 60 kilometers from here at Nandi hills, the South Pennar and the Arkhavati cross each other.
The 1922-made sewerage system of the city is spread across two hundred and fifteen square kilometers. Bangalore’s sewage is carried away by the Vrishabhavati River as well as the Arkhavati River.
