Geography

Kathmandu is in the northwestern part of the Kathmandu Valley to the north of the Bagmati River and covers an area of 50.7 km (19.6 sq mi). The average elevation is 1,400 metres (4,600 ft) above sea level. The city is bounded by several other municipalities of the Kathmandu valley: south of the Bagmati by Lalitpur Metropolitan City (Patan), with which it forms one urban area surrounded by a ring road, to the southwest by Kirtipur and to the east by Madyapur Thimi. To the north the urban area extends into several municipalities; Nagarjun, Tarakeshwor, Tokha, Budhanilkantha, Gokarneshwor and Kageshwori Manohara. However, the urban agglomeration extends well beyond the neighbouring municipalities, e.g. to Bhaktapur, and nearly covers the entire Kathmandu Valley.

Kathmandu is dissected by eight rivers, the main river of the valley, the Bagmati and its tributaries, of which the Bishnumati, Dhobi Khola, Manohara Khola, Hanumante Khola, and Tukucha Khola are predominant. The mountains from where these rivers originate are in the elevation range of 1,500–3,000 metres (4,900–9,800 ft), and have passes which provide access to and from Kathmandu and its valley. An ancient canal once flowed from Nagarjuna hill through Balaju to Kathmandu; this canal is now extinct.

The city of Kathmandu and the surrounding valley are in the Deciduous Monsoon Forest Zone (altitude range of 1,200–2,100 metres (3,900–6,900 ft)), one of five vegetation zones defined for Nepal. The dominant tree species in this zone are oak, elm, beech, maple and others, with coniferous trees at higher altitude.
