ODISHA: STATE 
GENERAL INTRODUCTORY PROFILE

Odisha, a state in the eastern coast of India has a geographical area of 1, 55,707 km2 and is divided in to 30 administrative districts and 314 blocks. Five physiographic units such as coastal plains, northern uplands, erosional plains of Mahanadi valley, south-western hilly region and subdued plateaus are observed in the state. There are eight major river basins within the State and the Indravati, Kolab, Machakund sub basins forms part of Godavari river basin. Most of the rivers flow easterly and southeasterly. The state enjoys a humid tropical climate and the normal rainfall in the State is 1502mm. The state is underlain by varied geological formations ranging in age from Pre-cambrian to Recent period.

Hydrogeology

The State is underlain by diverse rock types ranging in age from Archaean to Recent. The State can be hydrogeologically sub divided into consolidated, semi-consolidated & unconsolidated formations. The consolidated formations include hard crystallines and compact sedimentary rocks whereas semi-consolidated formations include weathered and friable Gondwana sedimentaries and loosely cemented Baripada beds. The unconsolidated formations include laterites and recent alluvium. The yield of tubewells tapping granite gneisse ranges between 10-35 m3/hr whereas other consolidated formations, it ranges between 5-18 m3/hr. The yield of tubewells in semi-consolidated formations range between 20-115 m3/hr.
