I. The Eastern Plain Region: 

The eastern region of Rajasthan is a plain area which lies to the east of Aravalli. It includes the plain areas of Bharatpur, Alwar, Dhaulpur, Karauli, Swaimadhopur, Jaipur, Dausa, Tonk and Bhilwara districts. It is the river basin region made of the mud deposited by the rivers. 

This plain region has three sub-regions: 

1. Banas-Banganga Basin 

2. Chambal Basin 

3. Central Mahi-Basin and Chhappan Plain

(1) Banas-Banganga Basin: 

It is a vast plain made by the mud deposited by the Banas and its auxiliary rivers such as Banganga, Berach, Kothari, Dane, Sahodara, Manasi, Dhundh, Bandy, Morel, Vagan, Gambhir, etc. This plain region is between 150 m to 300 m high from the sea level and its steep is eastward. 

(2) Chambal Basin: 

It includes Kota, Sawai Madhopur, Karauli and Jodhpur districts. Kota falls in Hadauti, but it has the Chambal plain region. 

(3) Central Mahi-Basin and Chhappan Plain: 

It extends over Dungarpur, Banswara and Pratapgarh districts from south-east Udaipur. The river Mahi flows through it. This river arises from Madhya Pradesh, passes from here and drains into the Bay of Khabhat. It is an uneven region and there are small hills all around. As it is the hilly region, it is known as ‘Bangar’ in the local dialect. There is a group of 56 villages between Pratapgarh and Banswara; hence it is also known as the Chhappan Plain.

II. South-East Plateau Region or Hadauti: 

South-East part of Rajasthan is a plateau region which is known as the Hadauti Plateau. It is the extension of the Malwa plateau and it has its spread over Kota, Bundi, Jhalwar and Baran districts. The average height of this area is 500 m and there are many small sized mountain ranges. Among them the Mukandara and the Bundi hills are prominent. The river Chambal and its auxiliaries as Kali Sindh, Parwan and Parvati rivers flow through it and the plains made by the mud deposited by these rivers are most suitable for agriculture.
