Gwalior district is one of the 52 districts of Madhya Pradesh state in central India. The historic city of Gwalior is its administrative headquarters. Other cities and towns in this district are Antari, Bhitarwar, Bilaua, Dabra, Morar Cantonment, Pichhore, and Tekanpur. The district is at the centre of the Gird region. The district has an area of 4,560 km2, and a population 2,032,036 (2011 census), a 25% increase from the 2001 census. Kaushlendra Vikram Singh has been the district collector since March 2020. Located in a transitional zone between the Malwa plateau and the Gangetic plain in Upper (Northern) Madhya Pradesh, Gwalior district consists of several distinct geographical areas. North and east of Gwalior city there is a broad alluvial plain, mostly flat and covered in dumat, parua, and kabar soils. The central part of the district, around Gwalior, is somewhat hilly, with sandstone outcrops that have often served as a source for building materials. These hills represent an extension of the Vindhyas, and their soil is often poorly suited for agriculture except in valleys and depressions. The average height of this hilly tract is about 80 feet above sea level. In the west is a plateau region, representing an extension of the Malwa plateau. This area is also hilly and some of it is covered by forests. The highest points are at Tor hill (at 1,454 feet above sea level) in the Sirkoli forest and Din hill (1,420 feet) in Rehat reserve forest. The Sind is the main river in Gwalior district. It begins in Vidisha district and then enters the southern plains of Gwalior at around 25°47' N. Much of the southeastern part of Gwalior district is an alluvial plain around the Sind and its tributaries. Other rivers that traverse the district include the Sank, Sonrekha, Morar, Vaishali, Nun, Chachond, and Asan. Because of the porous soil, all the rivers have eroded their banks to create ravines along their sides. This is more pronounced in the northern plain, and especially along the upper Vaishali river.
