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.

Four different news on River Sand Mining catch our eye, with common underlying theme of NEXUS of government and miners on the one hand and IMPUNITY of the sand miners in indulging in mindless violence. In Madhya Pradesh and Uttar Pradesh, no less than the Supreme Court (SC) and National Green Tribunal (NGT) respectively expose nexus between the state government and illegal sand mining. In Agra (UP again) the sand miners have again shown impunity in attempting to crush the forest officials trying to stop incessant illegal river sand mining from Yamuna River, they managed to run away, as usual. In Tamil Nadu, the High Court has appointed an advocate to ascertain the extent of illegal mining.
On any day, and in any sector, this should have been seen as eye widening affairs. It indeed should. But in sand mining this seems like regular dog biting man kind of news. One hopes it is not and that serious consequences follow. Kind of consequences that would not only help bring commensurate punishment to those responsible, but before that the identification of the guilty. And that punishment will be exemplary enough to bring some fear into the sand miners and those indulging in corruption in sand mining. It’s a bit tall order, but not unwarranted.

Guest Article by Rahul Banerjee
A laudatory article appeared a few months ago (April 2020) about how an IAS officer had cleaned up a 2 km stretch of the dirty Saraswati River (tributary of river Kahn or Khan) in Indore and it was brought to my notice recently[i]. The article claimed that this 2 km of stretch of River has been made “100% sewage free” “by treating inflow from 28 sewage lines through a fully functional Sewage Treatment Plant (STP)”.

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.”

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.

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.

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.

In a rather unusual development, no less than twenty districts in contiguous areas of Madhya Pradesh, Rajasthan and Gujarat had extremely high rainfall in the 48 hours ending at 830 am on Aug 23, 2020. Three of these districts had over 250 mm rainfall in this period, four others had between 200-250 mm, six each between 150-200 and 100-150 and one between 90-100 mm. This contiguous area broadly drains Mahi river to the West, Chambal to the North, Narmada to the South and Betwa to the East. These rivers, thus are now getting heavy flows, and will continue to get for the next few days, some of it from Chambal and Betwa will also end up in Yamuna and Ganga. It reminded one of the nightmarish memories of Sept 2019 when Gandhi Sagar Dam faced existential crisis and the flood peak downstream reached upto Farakka Dam, as CWC Flood forecasting director Sharad Chandra said in a television discussion recently.

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.
