Post Monsoon 2020: State wise Rainfall

According to India Meteorological Department (IMD), during the just concluded Post Monsoon Rainfall for 2020, that included rainfall during Oct-Dec months, India received 124.6 mm rainfall, 0.64% above the normal rainfall of 123.8 mm during the period. As per IMD[i] definition, the rainfall was thus normal.

This three-month period from Oct 1, to Dec 31 includes the North East Monsoon that mainly affects parts of South India including Tamil Nadu, Puducherry, Rayalseema, parts of Karnataka and Kerala. IMD declared on Jan 1, 2021 that the of NE Monsoon ended on Dec 31, 2020 with normal overall rainfall: TN had 6% above normal, Karnatak 13% above normal, Puducherry 32% above normal, Andhra Pradesh 33% above normal. However, Lakshadweep had 9% below normal and Kerala 26% below normal. This monsoon provides 48% of the annual rainfall of TN so it is most imp for that state.

The rainfall revived only towards the end of November, mainly due to two consecutive cyclones — Nivar and Burevi — both of which developed in the Bay of Bengal. While Cyclone Nivar crossed the coast close to Karaikal near Puducherry and brought heavy showers for the east and coastal districts of Tamil Nadu, Cyclone Burevi weakened before it reached land.

West Zone River Sand Mining Dialogue: Mining Riparian Health

River Sand Mining is equivalent to mining not only riparian health, but also destroying massive water storage and recharge capacity. This was one of the central message of the West Zone River Sand Mining Dialogue on Nov 12, 2020 (4-6.30 pm) as part of the India Rivers Week 2020[i] theme “Is Sand Mining Killing our Rivers?” The other central message of the West Zone Dialogue was well encapsulated by this quote from Yamuna Sunny, one of the panelists at the Dialogue: “The intricate relationships between the fishers, the small scale sand miners, the sand farmers, the birds and the trees, pertains not only to possibilities of developing sustainable ways of human life in an economic sense, but also the sustaining of all life forms and their relationships in nature.”

Krishna-Bhima basin floods in Oct 2020 breaks 56-year-old record

Krishna basin is again facing unprecedented floods, for the second straight year. Unprecedented is a bit of overused word these days, but consider the facts: At no less than ten locations, the Highest Flood Levels (HFL) ever recorded at those locations in the Krishna basin were surpassed (nine locations) or equaled (one location). Some of the HFLs surpassed this year were amazing 56, 51 and 44-year-old records! And imagine most of this happening in second half of Oct 2020, when South West monsoon is traditionally over by end of Sept! There is no doubt the floods were unprecedented.

Photo Story:Worm Collectors of a Polluted River

For the past few years, I walk along the bridges and riverbanks of Pune, taking pictures of the unique happenings here. I have made several silent friends who sit at the riverbanks grazing their cattle, or recline on the bridges, looking at the river. As a photographer, their body language and stories have fascinated me, as has the river.

Monsoon 2020: District Wise Rainfall

India received 957.6 mm rainfall in Just concluded South West Monsoon 2020, during the scheduled 4 month monsoon from June 1 to Sept 30, 2020. This is 8.74% above normal monsoon rainfall of 880.6 as per India Meteorological Department (IMD). This is considered ABOVE NORMAL rainfall, since rainfall is in the range 4-10% above Normal rainfall. This sounds good at national level, but the situation on ground could be very different, if we see the rainfall across the country.

It is noteworthy as per even IMD, monsoon has not yet withdrawn from most parts of the country. But IMD closes its monsoon rainfall account at 0830 hours on Sept 30, so all rainfall after that hour has to be counted in “Post Monsoon” rainfall book, even though the rainfall is very much part of monsoon as per IMD.

SSD induced Bharuch Flood disaster: Reality behind SSNNL claims that it saved Bharuch

We showed on Sept 2, 2020[i] using official information that Sardar Sarovar Dam (SSD) created an avoidable flood disaster in Bharuch, downstream of SSD starting on Aug 29, 2020, due to sudden, adhoc release of massive quantities water upto 10.72 lakh cusecs. The Sardar Sarovar Narmada Nigam Limited (SSNNL), official agency responsible for operation of the SSD is yet to provide any clear, coherent and fact based response. However, some of the spokespersons of SSNNL/ Government of Gujarat (GOG) are claiming that scientific operation of SSD saved Bharuch from bigger disaster. While this claim has no basis, this is like spraying salt on the fresh wounds.

Only an independent (not by serving or retired bureaucrats of the government) investigation would be able to bring out the truth as to how SSD operated, how it should have been operated, who is responsible for the massive disaster that Bharuch experienced, how can we fix accountability and what lessons we can learn for future.

District wise rainfall in June-Aug 2020 in India

In the ongoing South West Monsoon, India received 44 year old high surplus rainfall of 327 mm in just concluded Aug 2020, 26.6% above normal rainfall of 258.2 mm. This helped the total June-Aug 2020 rainfall to achieve 10% surplus, with actual rainfall 780.3 mm, 69.9 mm higher than normal rainfall of 710.4 mm. In June the country received 18% above normal rainfall and in July it received 9.9% below normal rainfall, the rainfall at the end of June was just 1.1 mm above normal. Thus almost the entire surplus rainfall is thanks to the rainfall during Aug 2020. The rainfall distribution has however, been far from normal that these figures suggest, as we can see from the state wise and district wise figures below.

Central India downpour brings unprecedented flows in Brahmani, Chambal, Godavari, Mahanadi, Narmada, Suvarnarekha

A massive wave of flood is flowing down the rivers originating in Central India states from Odisha in East to Gujarat-Rajasthan in the west. At least fourteen river sites have seen breach of Highest Flood Levels (HFL) in last four days, a record by itself: 7 in Mahanadi, 5 in Godavari, 2 in JNarmada and one each in Suvarnarekha and Chambal. In at least four of these cases, the earlier HFL had survived for 26 years and has now been broken.

The flood wave that is traveling down is above above 35500 cumecs (12.54 lakh cusecs) in Narmada (at Indira Sagar Dam), above 25000 cumecs (8.83 lakh cusecs), in case of Mahanadi (at Hirakud Dam) and Godavari (at Gosikhurd Dam) rivers & over 15000 cumecs (5.3 lakh cusecs) in Chambal (at Gandhi Sagar Dam) River.

District wise Rainfall in India in June July 2020

During the just concluded first half of the South West Monsoon 2020, India received 453.3 mm rainfall, just 1.1 mm above the normal rainfall of 452.2 mm during the period. The Surplus of  18% rainfall that India received in June 2020 has thus been wiped out by the 9.9% deficit in July rainfall. Normal rainfall in July 2020 is 285.3 mm, while actual rainfall was 257.1 mm. IMD does not provide monthly figures of rainfall for different states, sub divisions and river basins, which it should along with comparison with respect to normal rainfall and rainfall last year.

To get July 2020 rainfall, we will need to use the figures given in this article along with the figures of June 2020 rainfall (see: https://sandrp.in/2020/06/30/district-wise-rainfall-in-india-in-june-2020/). The district wise figures of June-July 2020 rainfall can be seen in this PDF file from IMD: IMD DISTRICT WISE RAINFALL FROM JUNE 1 TO JULY 31 2020.

Beyond technological failure: Examining the role of religious organisations in water conservation

Guest Blog by Sachin Tiwale

Introduction 

In summer of 2016, after witnessing two consecutive droughts, Art of Living (AoL) along with RSS Jankalyan Samiti, (RSS-JS) initiated Manjra River Rejuvenation program with the involvement of local leaders and residents. As a part of this program, the Manjra River channel was deepened and widened to create additional storage to meet the drinking water demand of parched Latur city of Marathwada, Maharashtra. During implementation, the leading organisations AoL and RSS-JS proclaimed rejuvenation project as a permanent measure resolving the crisis by creating storage of 18 million cubic metre (MCM) enough to meet Latur city’s water demand (Ghadyalpatil  2016; Thomas 2016). With a promise of supplying piped water every alternate day, they collected around Rs. 70 million from the people[1]. However, as described below, even after completion of massive excavation damaging river ecology, this project failed miserably. It could not even supply one drop of water to the citizens of Latur. Surprisingly, this failure is never revealed or discussed and on the contrary, the project was celebrated as a success (Samvada, 2016).
