Mullaperiyar issue by central soil and material research station team


           If Mullaperiyar and Idukki dam smashed, kerala will break into two parts. This is reported by Central Soil and material research station team. Intelligence collected this secret report. The scanning of upstream side of the Mullaperiyar dam using a remote operated vehicle by the Central Soil and Materials Research Station on directions from the Empowered Committee of the Supreme Court had found serious damage to the masonry structure between 95 to 106 feet from the base of the dam, retired engineer M. Sasidharan who was observer of Kerala during the scanning said in a report to the government.
It is reported that examination conducted as per the instructions of the high power committee of the Supreme Court have found severe cracks on the Mullaperiyar dam. The cracks were found in the examinations conducted by the Central Soil and Material Research station. If Mullaperiyar fails, Idukki reservoir will be affected, as a result Kerala topography will be changed by dividing the state into two regions. This confidential report has been gathered by Intelligence dept.
The studies were carried out for Kerala govt by expert team including Dr. P.K.Thampy (former CESS Geoscience head), Dr. A V George (M G University Disaster Management dept head) and geological science of India former head Dr. M.N. Nair. Idukki dam has a capacity of holding 70 TMC water and 79% of it is already filled. Hence it won’t be able to hold the water coming from Mullaperiyar and it would also collapse leading to a flood of enormous magnitude which would wash away four districts of Kerala.



If Water Bomb Blast - Mullaperiyar




The kerala peoples are eagerly looking for the Mullaperiyar issue. They are feared about the mullaperiyar dam break and leakage.




Here is the talks by some experts :-
  •  If Mullaperiyar dam broken The water will go on 50 feet heights to Idukki Dam.
  • Within 45 minutes water will reach at Idukki dam.
  • If Idukki dam got broken under the 11 dams will in critical stage.
  • Within 15 minutes Kochi will happen transportation blocks.
  • Water will reach at kochi within 3 hours.
  • Bhoodhathan kettu, kaladi, aluva places will be in dangerous stage.
  • If water flow in heavy the Neryamangalam bridge will be split.
  • It will effect  Kanirappalli, kottayam, cherthala, vaykkam, pala, eerattupetta aroor, kochi, thrippunithara, kakkanad, aluva, angaamli, kaladi, perumbavoor, muvvattupuzha, thodupuzha, malankara dam, kulamavu dam, vandiperiyar, elappara, kumali, idukki reservoir, idukki arch dam, cheruthoni dam, thattekaad, kothamangalm, neryamangalam places.
 Possibilities of Accident

  • Earthquake
  • Time-limit of Mullaoeriyar dam
  • Runny Alkali
  • Prodution without in blocks manner


Transportation Blocked to Tamilnadu by Mullaperiyar Issue

      
        Tamilnadu and Kerala got blocked transportation facilities On the mullaperiyar issue by Various groups. Coimbatore, Gopalappuram nadappuni, Valayar chavadi, Pollachi are the places that got blocked from early morning onwards. Those states vehicles are got block at border places.
      Check posts at Walayar on the Palakkad-Coimbatore border, Kaliyakkavila on the Thiruvananthapuram-Kanyakumari border, Kumily-Kambammettu on the  Idukki-Theni border and Aryankavu on the Kollam-Sengottai border were closed on Wednesday following blockade by the MDMK on the Tamil Nadu side opposing the construction of a new dam in place of the Mullaperiyar dam across the river Periyar in Kerala. A group of protestors owing allegiance to Naam Tamizhar party blocked the high way and prevented the vehicles coming to Kerala.Members of PMK and MDMK also joined the protest and staged demonstrations by squatting on the main road. Three vehicles carrying pilgrims to Palani from Neyyatinkara, were attacked by a mob in Tamil Nadu.

Mullaperiyar Dam Construction

                                                        DAM CONSTRUCTION


 The location of the dam had first been scouted by Captain J. L. Caldwell, Madras Engineers (abbreviated as M.E.) in 1808 to reconnoitre the feasibility of providing water from the Periyar river to Madurai by a tunnel through the mountains. Caldwell discovered that the excavation needed would be in excess of 100 feet in depth and the project was abandoned with the comment in his report as "decidedly chimerical and unworthy of any further regard".The first attempt at damming the Periyar with an earthen dam in 1850 was given up due to demands for higher wages by the labour citing unhealthy living conditions. The proposal was resubmitted a number of times and in 1862, Captain J. G. Ryves, M.E., carried out a study and submitted proposals in 1867 for another earthwork dam, 62 feet high. The matter was debated by the Madras Government and the matter further delayed by the terrible famine of 1876-77. Finally, in 1882, the construction of the dam was approved and Major John Pennycuick, M.E., placed in charge to prepare a revised project and estimate which was approved in 1884 by his superiors.
In May 1887, construction of the dam began. As per "The Military Engineer in India" Vol II by Sandes (1935), the dam was constructed from lime stone and surkhi (burnt brick powder and a mixture of sugar and calcium oxide, one of the archaiced construction techniques of 19th century) [4] at a cost of INR 104 lakhs, was 173 feet high and 1241 feet in length along the top and enclosed more than 15 thousand million cubic feet of water.[5] Another source states that the dam was constructed of concrete (no real evidence or reference for this) and gives a figure of 152 feet height of the full water level of the reservoir, with impounding capacity of 10.56 thousand million cubic feet along-with a total estimated cost of INR 84.71 lak.
The dam created a reservoir in a remote gorge of the Periyar river situated 3,000 feet above the sea in dense and malarial jungle, and from the northerly arm of this manmade waterbody, the water flowed first through a deep cutting for about a mile and then through a tunnel, 5704 feet in length and later through another cutting on the other side of the watershed and into a natural ravine and so onto the Vaigai River which has been partly built up for a length of 86 miles, finally discharging 2000 cusecs of water for the arid rain shadow regions of present-day Theni, Madurai District, Sivaganga District and Ramanathapuram districts of Tamil Nadu, then under British rule as part of Madras Province (Sandes, 1935).
The Periyar project, as it was then known, was widely considered well into the 20th Century as "one of the most extraordinary feats of engineering ever performed by man".The greatest challenge was the diversion of the river so that lower portions of the great dam could be built. The temporary embankments and coffer-dams used to restrain the river waters were regularly swept away by floods and rains. An extremely large amount of manual labour was involved and the mortality of the workers from malaria was extremely high. It was claimed that had it not been for "the medicinal effects of the native spirit called arrack, the dam might never have been finished". The construction also involved the use of troops namely, the 1st and 4th battalions of the Madras Pioneers as well as Portuguese carpenters from Cochin who were employed in the construction of the coffer-dams and other structures.

About Mullaperiyar Dam

                                                  ABOUT MULLAPERIYAR DAM


Mullaperiyar Dam is a masonry gravity dam over Periyar River and its tributary Mullayar, hence Mullaperiyar.

Height : 176 ft [ 54 m ]

Long   : 1200 ft [ 366 m ]

Location : 2,889 ft (881 m) above mean sea level on the Cardamom Hills of Western Ghats in Thekkadi, Idukki District of Kerala, India.

Construction : 1895 by the British Government, to divert water eastwards to Madras Presidency area (the present-day Tamil Nadu).
Landmark : The Periyar National Park, Thekkady is located around the dam's reservoir.

                       Even-though the dam and the river are fully owned by and located in Kerala , the dam is controlled and operated on a period lease by Tamil Nadu. The safety of the dam has been a matter of concern and a point of dispute between Kerala and Tamil Nadu States.
                      The name of Mullaperiyar dam is derived from a portmanteau of Mullayar and Periyar.As the dam is located in the convergence of the Mullayar and Periyar rivers, the river was called Mullaperiyar. The Periyar National Park, Thekkady is located close to the park Periyar reservoir. The backwaters of this dam form this park.
Purpose :The water utilization is mainly for irrigation purpose.
