Which of the following pairs are correctly matched? 1. Idukki: Thermal Power Station 2. Sabarigiri: Hydroelectric project 3. Ghatprabha: Irrigation project 4. Ramganga: Multipurpose project Correct Answer 2, 3 and 4

The correct answer is 2, 3 and 4.

Key Points

  • The Idukki Dam is a double curvature arch dam constructed across the Periyar River in a narrow gorge between two granite hills locally known as Kuravan and Kurathi in Kerala, India. 
    • It is one of the highest arch dams in Asia.
    • It is constructed and owned by the Kerala State Electricity Board.
    • It supports a 780 MW hydroelectric power station in Moolamattom, which started generating power on 4 October 1975.
    • The dam type is concrete, double curvature parabolic, thin arc dam.
  • Hence, option 1 is correct.

Additional Information

  • Sabarigiri: Hydroelectric project
    • Sabarigiri Hydro Electric Project (IHEP) is the second-largest hydroelectric project in Kerala.
    • The project was commissioned in 1966 with an installed capacity of 300 MW.
    • The RMU of the Project was undertaken during the period from 2005 to 2009, increasing the installed capacity to 340 MW.
    • The dams at Sabarigiri have dried up as the Southwest Monsoon is delayed for more than a month.
      • Only seven per cent of the water remains in Sabarigiri.
      • So the electricity generation is moving towards crisis. 
  • Ghatprabha: An irrigation project
    • It is a tributary of Krishna that flows in Karnataka.
    • Ghataprabha has a hydroelectric and irrigational dam at Hidkal.
    • The dam was completed in 1977.
    • To make it a multipurpose project a reservoir was also constructed on the dam.
    • Tributaries of Ghataprabha: Hiranyakeshi and Markandeya rivers.
  • Ramganga: Multipurpose project
    • The Ramganga Dam, also known as the Kalagarh Dam.
    • It is an embankment dam on the Ramganga River 3 km upstream of Kalagarh in Pauri Garhwal district, Uttarakhand, India.
    • It is located within the Jim Corbett National Park.
    • The dam is part of the Ramganga Multipurpose Project —
      • irrigation and hydroelectric project.

1996-7 and 2002-3, the area under canal irrigation declined by 2.4 million ha (13.8 percent), the area under tank irrigation fell by 1.4 million ha (42.4 percent), and the area irrigate by all other sources declined by 1 million ha (28 percent). The only irrigation source that increased its share was groundwater wells, by 2.8 million ha (more than 9 percent) Why has such a change in irrigation demands happened? 1. Not enough supply of water from canals 2. More tubewell irrigation by farmers in the source areas of rivers 3. High cost of irrigation water, and  diversion for non-farm use 4. Joint use of water not possible due to social and economic inequalities
There is only one rail track between stations A and B on a railway line. One hour after the northbound superfast train N leaves station A for station B, the southbound passenger train S reaches station A from station B. The speed of superfast train is twice that of express train E, while the speed of passenger train S is half of that of train E. On some one day train N leaves from station A to station B 20 minutes late than its usual schedule. Both Train N and Train S have increased their speed to maintain the schedule as per the table. If the superfast train doubles its speed, then what should be the ratio (approximately) of the speed of the passenger train to the speed of the superfast train so that the passenger train reaches the station on that day at the exact scheduled time.
