2.1 Study Area

Delhi is located at 28°61′N, 77°23′E, and lies in Northern India. The national capital territory (NCT) is stretched over an area of 1483 km2. Delhi is located approximately 213–305 m above sea level. Delhi stands in the middle of the Indian subcontinent, between the Himalayas and Aravalli’s range bordered by Haryana in East and by Uttar Pradesh across the river Yamuna. Yamuna enters Delhi near Palla village after covering a distance of about 400 km from its origin and exits from Delhi (NCT) at the village Jaitpur after traversing a distance of 50 km within the NCT (Report: Knowledge, Attitude, and Practice of Delhiities towards the River Yamuna). Two prominent features of Delhi’s geography are Yamuna flood plain and Delhi ridge. The ridge forms the most dominant feature in this region. Aravallis extend from Gujarat through Rajasthan to Haryana up to Delhi. The spurs of Aravallis are popularly known as ‘Delhi ridge in Delhi’, which is divided into Northern, Central, South central, and Southern ridge.

Delhi sprawls an area of 1500 km2. Its east–west length is approximately 51.9 km and the northwest width approximately 48.48 km. The spread of Delhi is somewhat circular. The transportation network in Delhi is predominately road based. Delhi has the largest road length of 1284 km/100 km2 of area in India. The road network in the city is 22,487 km long. Engineering, clothing, and commercial activities predominate although electrical goods are gaining importance. Most industries are located in the west, south, and southwest of the city. Delhi has two major thermal power plants, which are not sufficient to cater to the total power need of the city. Generator sets are thus used in commercial, residential, and industrial areas as backup power. Cooking, generator sets, various internal combustion engines, burning of organic wastes landfill, sewage treatment plants, slums, and open defecation are some of the sources of VOCs in Delhi.
