| Mapping Symbol | Hydro geomorphic Units | Litho-Stratigraphy | Structure | Description | Ground water prospects |
| SV | Structural valley | Basalts | Associated with Fractures/ Lineaments | The valley portions of basalts weathered to a considerable depth and associated with fractures/ lineaments. | Moderate to good. Good yields are expected along Fractures/Lineaments. |
| MDP | Moderately dissected plateau | Basalts | -do- | Shallow valleys/Gullies with gentle sloping land developed due to stream erosion on plateau. | Poor to moderate. |
| MLP | Moderately thick lateritic plateau | Laterites as capping over basalts | -do- | Elevated flat land with moderately thick lateritic Plateau. | Moderate. Ground water occurs mainly in the weathered and fractured zones of basalts. |
