Physically the natural capital territory of Delhi can be divided into 3 segments - the Yamuna flood plain, the Ridge and the Plain. The Yamuna flood plains are somewhat low-lying and sandy and are subject to recurrent floods. This area is also called Khadar. The ridge constitutes the most dominating physiographic features of this territory. It originates from the Aravali hills of Rajasthan and entering the union territory from the south extends in a north eastern direction. It encircles the city on the north west and west. The point near Bhatti has a height of 1045 ft. Tughlaquabad fort is located on one of the highest spurs of the ridge. Leaving aside the Yamuna flood plain (khadar) and the ridge, the entire area of the national capital territory of Delhi is categorized as Bangar or the plain. A major proportion of the area of Delhi is plain and on this are located Delhi, New Delhi and Delhi cantonment along with a vast stretch of numerous villages. The land of the plain is mostly fertile.
Yamuna is the main river which passes through the territory. Apart from the flood channels of Yamuna, there are 3 canals i.e., portion of Agra Canal, Hindou Canal and western Yamuna Canal.
In Delhi, there are 5 community development blocks comprising of 209 villages of which 199 villages are inhabited while the remaining ten villages are uninhabited.
