GEOMORPHOLOGY

GEOMORPHOLOGY

Geomorphology maps help to identify the various geomorphic units and groundwater occurrence in each unit. Selected and limited field checks are carried out in the field to verify the different geomorphic units.
An overall appraisal of ground water occurrence in each geomorphic unit and the significance of its hydro geological characters are furnished with groundwater potential. Even though the groundwater potential zones are demarcated based on subsequent field checks, the present extraction of ground water has to be taken into consideration before implementing further groundwater schemes. Coleroon River is flowing on the south of the district and the vellar river is flowing on the north of the district. Alluvium is deposited on the northern and southern side of the rivers and occurs as alluvial plain.
