Pagara Masonry Dam was constructed about 94 years from now during the period 1911-1917 in Gwalior (M.P.). After construction, it has breached/damaged and rehabilitated three times.

In hydro electric projects, grouting plays an important role in controlling the seepage and improvement in rock strength for the construction of underground as well as surface structures. The Nathpa Jhakri Hydroelectric Power Station (NJHPS) 1500 MW, the largest hydropower station in India under operation, and downstream Rampur Hydro Electric Project (RHEP) 412 MW, presently under advanced stage of construction, and planned to run in tandem are both located on river Satluj in the Himalayan region.

Small hydropower (SHP) is one of the most common renewable, economic, non-consumptive, non-radioactive, non-polluting and environmentally benign sources of energy. A vast potential of small hydropower is available on canals falls under the range of low head hydropower schemes.

CHENNAI: Taking strong exception to Kerala's reported "unilateral" action in ordering real time monitoring of Mullaperiyar Dam along with the Centre without Tamil Nadu's consent, Chief Minister Jayalalithaa today slammed it as a "blatant violation" of the principle of federalism and constitutional framework. In a letter to Prime Minister Manmohan Singh, she referred to reports of Kerala deciding "unilaterally" to install real time monitoring system for water build up, calling it yet another attempt to exacerbate fears in Kerala about its safety.

Grout material in recent years has made quantum advancement and researchers have made this material more application friendly. Grouts are finding increasing applications for checking seepage under dams and in repair work for old dams.

Dam building activity in India got impetus and priority, after India became Independent. Total dams built in India up to year 2002 were about 4050. Maharashtra state has the largest number of large dams in India.

Keen on taking advantage of the national solar mission, the public sector Sutlej Jal Vidyut Nigam (SJVN) will make a foray into the renewable energy sector with a pilot solar power project in the state, to be set up alongside the Nathpa Jhakri project.

Pilot Project

Fishermen held a demonstration in the city on Tuesday against India’s controversial Tipaimukh dam saying it would adversely affect livelihoods and life of over three lakh fishermen in Bangladesh’s north-eastern districts.

Speaking at a rally in front of the National Press Club fishermen’s leaders said that at least 10 rivers in Bangladesh including the Surma, Kushiyara and Meghna would dry up causing gradual desertification in the northeastern districts of lower riparian Bangladesh.

They said it would directly affect the life and livelihood of the country’s fishermen.
