B. E. Civil Engineering students (2008 – 2012 batch) of Dr. Mahalingam College of Engineering and Technology went on an Industrial visit to Parambikulam Aliyar Project (PAP) on 13-8-2010. The following are the details of places visited: 1. Parambikulam dam. 2. Walk through the Infiltration Gallery of Parambikulam dam. 3. Thunakadavu dam. 4. Wildlife Museum located in Top Slip. PARAMBIKULAM – ALIYAR PROJECT (PAP) is a joint venture project between the Governments of Tamil Nadu and Kerala. It consists of eight interconnected dams. Five dams are situated in Tamil Nadu and the remaining three in Kerala. The reservoirs lie at various elevations ranging between elevation + 3780 feet and + 1050 ft. and this difference of elevations has made it possible to utilize the drop between them for the development of hydroelectric power. 2 AIM OF THE PROJECT: The Parambikulam Aliyar Project (PAP) successfully accomplishes the diversion and integration of 8 West flowing rivers; 6 in the Anaimalai Hills and 2 in the plains- for the benefit of the drought prone areas in the Coimbatore and Erode Districts of Tamilnadu State and stabilizing the existing irrigation system in Chittoorpuzha of Kerala State. Dams on the 8 rivers with inter connecting tunnels have been constructed. They divert the west flowing waters to the east and irrigate the plains of the Coimbatore District and Erode District of Tamil Nadu State and Chittur area of the Kerala State. The main components of this project comprises of 8 Dams, 4 Power Houses, 6 Main Tunnels and 7 Irrigation canals.

It runs in a South Westerly direction and falls into Edamalayar, the major tributary of Periyar river. 3.1.1 HYDRAULIC PARTICULARS District -- Coimbatore State -- Tamilnadu Basin -- Periyar Catchment area -- 29 sq.miles (11 T.Nadu 18 Kerala) Area of Water spread -- 0.07 Sq.miles Full Reservoir level -- 3800 feet Maximum Water level -- 3800 feet Deepest Foundation level -- 3714.70 feet Capacity at FRL -- 39 MC.ft Construction cost of Dam -- Rs.178 Lakh 3.2 LOWER NIRAR DAM:- A dam across Nirar River at a lower site, about 8 Km, below the Upper Nirar weir has been constructed. This dam will conducts the diverted waters of Anamalaiyar Basin to the Sholayar valley through the un-lined lower Tunnel taking off from the dam site. In addition to this, the yield of the catchment between the Upper Nirar Weir and the Dam will also be diverted to the Sholayar Basin. 3.2.1 HYDRAULIC PARTICULARS District -- Coimbatore State -- Tamilnadu Basin -- Periyar Page 6 of 20 REPORT ON INDUSTRIAL VISIT TO PAP ON 13.08.2010 Catchment area -- 39 Sq. miles (21 T.Nadu 18 Kerala) Area of Water spread -- 0.2 Sq.miles Full Reservoir level -- 3350 feet Maximum Water level -- 3350 feet Deepest Foundation level -- 3195 feet Capacity at FRL -- 274 MC.ft Construction cost of Dam -- Rs. 547 Lakhs 3.3 SHOLAYAR RESERVOIR:- Sholayar river is one of the main tributaries
