The study area is situated in the eastern part of Palakkad district of KeralaState and is bounded on the north by Attapady block, in the east by Coimbatore district of Tamil Nadu, in the south by Kollengode block and in the west by parts of Kuzhalmannam, Alattur and Palakkad blocks. The area lies between North latitudes 100 36' 34'' and 100 56'33'' and East longitudes 760 32'42'' and 760 54'28'', covering an areaof about 1000 sq.km of which 300 Sq Km falls under hilly and forest category and the balance 700 Sq. Km is considered for aquifer mapping. The mapping area includes whole of Malmpuzha and Chittur blocks and part of Kuzhalmannam, Kollangode, Alattur and Nenmara blocks.The area falls in parts of Survey of India topo sheets 58B/9, 10, 13 and B/14 and is served by a good network of roads and rail connecting important adjoining places in Kerala and Tamil Nadu. The National Highway NH 47 and the broad gauge rail sectionsof Southern Railway such as Thiruvananthapuram-Palakkad-Coimbatore-Chennai and Palakkad- Pollachi railspasses through the area. The area is mainly drained by Bharathapuzha’s tributaries namely Gayathripuzha, Kannadipuzha Chitturpuzha and Kalpathypuzha. Gayathripuzha originates in Anamali hills and flows along NW - SE trending faulty valley through Kollengode, Nenmara, Vadakancherry, Alathur and Pazhayannur before its confluence with Ponnani River (Bharathapuzha) at Mayannur. The Kannadipuzha has three sub-tributaries viz; Palar, Aliyarand and Uppar. Kalpathypuzha originates south of Coimbatore and flows roughly in an E - W trend. It has four sub-tributaries viz - Korayar, Varattar, Walayar and Malampuzha. No additional data on drainage generated and the available information has been used in the present study. The study area is mainly comprised of Archaean metamorphic complex, predominantly the migmatite gneissic complex. Other rock formations such as charnockite and khondalite group of rocks cover less than 5% of the area. Intrusive rocks, pegmatite and quartz veins, are common in the eastern part of the area. Geomorphologically the area is characterized by the land features of mid land and high land regions.The prominant physiographic feature of the area is the Palghat gap which is a structural gap of about 32km wide developed in the Western Ghats. Palghat Gap is the only major break within the Western Ghats. Geomorphologically, three distinct physiographic horizons of both erosional and depositional types with characteristic soils have been discerned in the Gap area.
