  Ahmedabad lies in western India at 53 metres (174 ft) above sea level on the banks of the Sabarmati river, in north-central Gujarat. It covers an area of 505 km 2 (195 sq mi). The Sabarmati frequently dried up in the summer, leaving only a small stream of water, and the city is in a sandy and dry area. However, with the execution of the Sabarmati River Front Project and Embankment, the waters from the Narmada river have been diverted to the Sabarmati to keep the river flowing throughout the year, thereby eliminating Ahmedabad's water problems. The steady expansion of the Rann of Kutch threatened to increase desertification around the city area and much of the state; however, the Narmada Canal network is expected to alleviate this problem. Except for the small hills of Thaltej-Jodhpur Tekra, the city is almost flat. Three lakes lie within the city's limits— Kankaria, Vastrapur and Chandola. Kankaria, in the neighbourhood of Maninagar, is an artificial lake developed by the Sultan of Gujarat, Qutb-ud-din, in 1451.
  
  According to the Bureau of Indian Standards, the town falls under seismic zone 3, in a scale of 2 to 5 (in order of increasing vulnerability to earthquakes).
  
  Ahmedabad is divided by the Sabarmati into two physically distinct eastern and western regions. The eastern bank of the river houses the old city, which includes the central town of Bhadra. This part of Ahmedabad is characterised by packed bazaars, the pol system of closely clustered buildings, and numerous places of worship. A pol (pronounced as pole) is a housing cluster which comprises many families of a particular group, linked by caste, profession, or religion. This is a list of pols in the old walled city of Ahmedabad in Gujarat, India. Heritage of these pols has helped Ahmedabad gain a place in UNESCO 's Tentative Lists, in selection criteria II, III and IV. The secretary-general of EuroIndia Centre quoted that if 12,000 homes of Ahmedabad are restored they could be very helpful in promoting heritage tourism and its allied businesses. The Art Reverie in Moto Sutharvado is Res Artis center. The first pol in Ahmedabad was named Mahurat Pol. The old city also houses the main railway station, the main post office, and some buildings of the Muzaffarid and British eras. The colonial period saw the expansion of the city to the western side of the Sabarmati river, facilitated by the construction of Ellis Bridge in 1875 (and later the modern Nehru Bridge). The western part of the city houses educational institutions, modern buildings, residential areas, shopping malls, multiplexes and new business districts centred around roads such as Ashram Road, C. G. Road, and Sarkhej-Gandhinagar Highway.
  
  The Sabarmati Riverfront is a waterfront area being developed along the banks of the Sabarmati river in Ahmedabad, India. Proposed in the 1960s, its construction began in 2005, and it opened in 2012.
