In NEWS:CSE praises NTPC’s fly ash transfer move from its Rihand plant

Power giant National Thermal Power Corporation (NTPC) Ltd’s move to transfer fly ash from its 3,000-megawatt Rihand Super Thermal Power Station in Uttar Pradesh’s Sonbhadra to cement plants

About Fly Ash:

  • Fly ash or pulverized fuel ash is a by-product of burning pulverized coal in coal based thermal power plants. Hence statement 1 is correct
  • It is normally produced from burning anthracite or bituminous coal.
  • Depending upon source and composition of coal being burned, components of fly ash vary considerably.But all fly ash includes substantial amounts of Silicon dioxide (SiO2), Aluminium oxide (Al2O3) and calcium oxide (CaO).
  • It is also a valuable resource of important plant nutrients – Calcium, Magnesium, Potassium, Phosphorus, Sulphur, Boron, Iron, Copper and Zinc. Hence statement 2 is incorrect
  • Fly ash is a proven resource material for construction industries.
  • Its most relevant characteristics for use in concrete are loss of ignition, fineness, chemical composition and uniformity.
  • Utilization of fly ash in replacing cement in concrete mixture decreases both energy and CO2 emitted during production.
  • Net reduction in energy use and greenhouse gas when fly ash is used to replace or displace manufactured cement.

Bhadbhut project is built over which of the following river in india?

  • Narmada River
  • Tapi River
  • Godavari River
  • Ganga River

Answer: (a) Narmada River

Explanation:

In NEWS:Barrage across Narmada: promise of sweet water, worries about hilsa

  • Bhadbhut project in Bharuch is meant to solve freshwater problems in this region of Gujarat
  • The Gujarat government recently awarded the contract for a barrage project to a joint venture of DilipBuildcon Ltd and Hindustan Construction Company Ltd.

What is the Bhadbhut project?

  • It is planned to be a 1.7-km causeway-cum-weir barrage with 90 gates, across the river Narmada, 5 km from Bhadbhut village, and 25 km from the mouth of the river, where it flows into the Gulf of Khambhat. Hence option (a) is correct
  • The barrage will stop most of the excess water flowing out of the Sardar Sarovar Dam from reaching the sea and thus create a “sweet water lake” of 600 mcm (million cubic metres) on the river.
  • The barrage will also have a six-lane road that will connect the left and right banks of the river and provide shorten the land distance between two large industrial estates in Surat and Bharuch.
  • The project also aims to prevent flooding in years when rainfall is higher than normal. Embankments 22 km long will be made and will extend upstream towards Bharuch, from either side of the river.
  • The main purpose of the project is to prevent salinity ingress. At the beginning of the 21st century, an estimated 16.30 million acre feet (MAF) of water used to be released from the dam.
  • By 2017, when the height of the dam rose, flow into the river reduced to 4.7 MAF. Due to the reduced flow of fresh water, saline seawater gushes into the Narmada estuary during high tide, thus increasing salinity along the banks.

Which of the following statements with respect to ‘Hilsa’?

  • It is a marine fish
  • It is a sea grass
  • It is the state animal of Odisha
  • It was a joint navy operation between India and Myanmar.

Answer: (a) It is a marine fish

Explanation:

In NEWS:Barrage across Narmada: promise of sweet water, worries about hilsa

The project is part of larger Kalpasar Project (which entails construction of a 30-km dam across Gulf of Khambhat between Bharuch and Bhavnagar districts, meant to tap waters of the Narmada, Mahisagar and Sabarmati.)

Why are fishermen upset?

  • The barrage is expected to interfere with the migration and breeding cycle of hilsa.
  • Hilsais a marine fish that migrates upstream and arrives in the brackish water of Narmada estuary near Bharuch for spawning usually during monsoon (July and August) and continue doing so till November.Hence option (a) is correct
  • Once the barrage is built, it is expected to block their natural entry.
  • According to a study by Kolkata-based Central Inland Fisheries Research Institute (CIFRI),thefish production from Narmada estuary has fallen from 15,889 tonnes in 2006-07 to just 1,618 tonnes in 2014-15.
  • The reduced outflow of water from the dam, industrial effluents flowing into the river and salinity ingress are believed to be the major causes of this decline.
  • Part of Aliya Bet, and island in delta of Narmada, known for shrimp farming, is likely to get submerged due to the accumulation of water in Bhadbhut reservoir.
