DRP News Bulletin 11 May 2020: Jindal accepts Etalin HEP is unviable!

This must be the defining (and predictable, this was the lead story in our DRP NB of April 27, 2020, see: https://sandrp.in/2020/04/27/drp-nb-27-april-2020-for-whom-is-this-unviable-etalin-project-being-pushed/) moment in the campaign to save the Dibang Valley now from the proposed 3097 MW Etalin Hydropower Project. The CEO of Jindal Power Ltd has said in so many words that project is NOT an attractive investment, they will struggle to find buyers for the costly power and only support from government can help make the project viable. The CEO seemed to suggest that they would be happy to sell the project to NHPC or form a joint venture with NHPC to get the govt funding for the project. Again completely on predictable line. The question then is why should government spend previous public money on such an unviable project?

So the question remains the same, the one we asked on April 27, 2020: For whom is this unviable Etalin Project being pushed?

IMD’s 1st Long Range forecast for SW monsoon 2020

IMD’s 1st Long Range Forecast for SW Monsoon 2020 on Apr 15, 2020[i] says:

– Rainfall will be normal (100% of LPA: Long Period Average of 88 cm). IMD says Neutral El Nino Southern Oscillation prevails in Pacific Ocean and Neutral Indian Ocean Dipole conditions prevail in Indian Ocean, likely to remain throughout the monsoon as per most models, some indicate weak La Nina conditions in Pacific Ocean in second half of monsoon.

– FORECAST BASED ON MONSOON MISSION COUPLED FORECASTING MODEL There is high probability (70%) of monsoon rainfall being above average to excess (over 104% of normal)

– FORECAST BASED ON OPERATIONAL STATISTICAL ENSEMBLE FORECASTING SYSTEM: 9% probability of Deficient monsoon (Over 10% below normal); 20% probability of below normal (90-96% of normal) rainfall; 41% probability of normal monsoon (96-104% of normal rains); 21% probability of above normal (104-110% of LPA rains) and 9% probability of excess (over 110% of normal) rains.

Cleaner rivers in lockdown: Lessons we can learn

Within a week of 21-day long lockdown in India that started at midnight on March 24, 2020, several reports in print, electronic and social media have been doing rounds showing remarkable improvements in water quality in many rivers in the country. Most of these are on the basis of naked eye observations in the form of pictures and videos by people.

Some of the reports quote pollution control boards’ officials and experts with some analytical data. People generally believe that the shutting down of industrial units has led to reduction in discharge of industrial effluents in the rivers, breathing fresh life in pollution laden streams. It’s right that there is halt in industrial belts and there is less industrial pollution reaching the rivers. However there are other factors contributing to the change in the scenario.

ECONOMIC SURVEY 2020: WHERE IS THE GROUND REALITY?

One of the key objective of the Economic Survey is to provide an accurate account of ground realities on various aspects affecting the Economy of the country and also what has the govt been doing to address the issues that such an account throws up. From a look at the key issues that SANDRP focuses on, it seems that the Economic Survey for 2019-20 that was released on January 31, 2020 does not even attempt to provide an account of the ground realities.

Cloud Burst

Uttarakhand Cloud Bursts in Monsoon 2019: No Doppler Radars Six Years Since 2013 Disaster

With the beginning of south west monsoon season 2019, many Himalayan states started witnessing exceptional rainfall events known as Cloud Bursts. The extreme weather event – like previous years- caused large scale destruction in ecologically sensitive and remotely located vulnerable hilly areas. This account compiles the available information about such incidents in Uttarakhand in 2019 SW monsoon.

44% above normal rainfall in Oct 2019 creates hopes for Rabi, Disaster for Kharif crops at many places

The Oct 2019 rainfall all over India was 109.7 mm, 44% above normal expected rainfall of 76 mm, following 53% above normal in Sept 2019. The rainfall this month has been unusual and has had some major impacts. One of the reasons has been that the SW monsoon withdrawal continued well into Oct 2019, when it almost always gets over by the end of Sept. There were also several cyclonic circulations and depressions mostly from Arabian sea.

2019 Monsoon: Instances when Dam Safety Came into Question

The South West Monsoon in 2019 in India brought the highest rainfall of last 25 years and issues related to heavy rainfall continue even to the end of October 2019. Here we have listed major instances during the monsoon when there were question marks over safety of dams either due to structural safety or due to wrong operations of the dams. Some issues of breaches of embankments/ canals are also included here. As we can see, the instances come from across the country, including North East, North, West, Centre, South.

Rivers That Reached New Highest Flood Level during Monsoon 2019

In the monsoon season of 2019 Indian rivers have crossed Highest Flood Level (HFL) at around 37 Level Forecasting and Level Monitoring sites across the country. This account attempts basin wise details and description of HFL breached by the rivers.   

Brahmaputra Basin (Assam)

In Brahmaputra basin 2 sites, 1 Aie NH Xing Level Monitoring site on River Aie in Barpeta district of Assam and Dhubri (Level Forecast) site on River Brahmaputra in Dhubri district of Assam narrowly crossed the HFL in July 2019.

Also River Barak at ANIPUR   site in Karimganj district on May 24 and River Brahmaputra at Goalpara site in Goalpara district rose close to the HFL level on July 17, 2019. As per CWC (Central Water Commission) FF Website, Goalpara site has not crossed HFL since 1954.

River Wise Rainfall in Monsoon 2019

Indian media never seems to report this, but IMD (India Meteorological Department) also provides river basin wise rainfall figures for South West Monsoon, also for other seasons. As in the previous years, here is an overview of the river basin wise rainfall during just concluded SW Monsoon 2019 (June-Sept 2019, though the monsoon started withdrawing only on Oct 9 and has not yet fully withdrawn from across India as I write this on Oct 15 2019), like the way we have been doing for the last three years[i]. Our earlier monsoon 2019 articles provided monsoon over view[ii], state wise rainfall figures[iii] and Marathwada specific situation[iv].

It’s not clear why Indian media does not report river basin wise rainfall figures, since that is arguably, the most appropriate way to look at the rainfall figures, since river basins are the hydrological units and the run off from the rainfall ends up in the rivers, and creates floods many times, as happened during 2019 monsoon. There could be issues of quality of the river basin wise rainfall figures, but that is true for all IMD’s rainfall figures at some level or other.

Can floods lead to drought? After the flood, severe drought looming over Kerala

Guest blog by: Madhusoodhanan C.G. and Sreeja K.G

The state of Kerala experienced extreme precipitation events during the 2018 South West monsoon period with multiple episodes culminating in devastating floods across the state during 14th-18th August 2018. This year, with an early onset of monsoons that dovetailed with strong summer showers, the state received about 41% excess rainfall (2394 mm against the normal of 1700 mm) during the period June 1st to August 22nd [1]. Almost all of its reservoirs were near full storage by mid-July.

The heavy downpour and the uncontrolled opening of the spillway gates of almost all reservoirs that inundated huge stretches of river banks and floodplains, along with massive landslides across the Western Ghats affected more than 1.5 million people, with close to 500 human casualties, immense losses to property, livelihoods and resource security apart from the extensive damage to forests, wildlife and biodiversity. Maximum destruction was observed along the rivers of Periyar, Chalakudy and Pamba, all having multiple dams on their tributaries. The debate is still on as to the various reasons, both manmade and natural, behind the floods and the resultant wide-ranging casualties [2,3,4,5,6]. Meanwhile things have taken a rather unexpected turn in the flood ravaged state.
