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It is noteworthy as per even IMD, monsoon has not yet withdrawn from most parts of the country.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.

ભરૂચમાં પૂરની તારાજી માટે સરદાર સરોવર જવાબદાર

સરદાર સરોવર ડૅમ (SSD)ના સંચાલકો જરાય વિચાર કર્યા વિના, અને કહી શકો કે, ક્રૂરતાથી, પાણી કેટલું છોડવું, ક્યારે છોડવું તેના નિર્ણયો લે છે. એમના નિર્ણયની અસર હેઠવાસમાં શું થશે તેના પર તો જરાય ધ્યાન નથી આપતા.  કંઈ નહીં તો, ૨૬મી ઑગસ્ટ ૨૦૨૦થી જ એમને સત્તાવાર માહિતી મળી ગઈ હતી કે  ભારે વરસાદને કારણે નર્મદાના ઉપરવાસમાં પાણી વધવા લાગ્યું છે. આ માહિતી પર એ કામ કરી શક્યા હોત તેમ છતાં ૨૯મી ઑગસ્ટ, શનિવારની વહેલી સવાર સુધી એમણે ડેમનાં સ્પિલ-વે ગેટ્સમાંથી પાણી ન છોડ્યું.  ડૅમ ૭૦ ટકા ભરાઈ ગયો હોવા છતાં એમણે પાવર હાઉસો પણ ન ચલાવ્યાં. ઓચિંતા જ ૨૯મીની રાતે એમણે દસ લાખ ક્યુસેક – દર સેકંડે ઘન ફૂટ (૨૮,૩૨૦ ક્યુમૅક એટલે કે દર સેકંડે ઘન મીટર) પાણી  છોડવાનું શરૂ કરી દીધું [i].. ત્રણ દિવસ પછી ૧ સપ્ટેમ્બર, મંગળવારની સાંજે એમણે મોટા ભાગનાં સ્પિલ ગેટ બંધ કરી દીધાં. આમ સ્પિલ-વેમાંથી નીકળતા પાણીનો જથ્થો પહેલાં કરતાં માત્ર દસમા ભાગનો રહ્યો. આ ૩-૪ દિવસમાં (૨૯મી ઑગસ્ટ અને ૧લી સપ્ટેમ્બર વચ્ચે) પાણીનો ૩૦,૦૦૦ ક્યુમૅક સુધીનોજબ્બરદસ્ત જથ્થો સ્પિલ-વે મારફતે છોડવામાં આવ્યો; એના પહેલાં કે તેના પછી કંઈ જ નહીં! પરિણામે હેઠવાસમાં ગરૂડેશ્વરથી ચાંદોદ અને ભરૂચ સુધી પૂરનાં વિનાશકારી પાણી ફરી વળ્યાં. પરંતુ લાગે છે કે, સરદાર સરોવર પ્રોજેક્ટ (SSP)ના સત્તાવાળાઓ અથવા ગુજરાત સરકારના પેટનું પાણી પણ નથી હાલ્યું. હવે સમય આવી ગયો છે કે ગુજરાતની જનતા જાગે અને આ માનવસર્જિત તારાજી માટે SSPના ખેરખાંઓનો જવાબ માગે.

Sardar Sarovar Creates avoidable flood disaster in Bharuch

Sardar Sarovar Dam (SSD) operators are operating the dam callously, almost cruelly, without consideration of the impact of the operation in the downstream area. Till Saturday-Aug 29, 2020 early hours, they were not releasing any water from the spillway gates of the dam, in spite of sufficient actionably information at least since Aug 26 that rainfall is hugely increasing in upstream Narmada basin. They were not even operating powerhouses even though the dam was close to 70% full. Suddenly, by Aug 29 night they started releasing upto ten lakh cusecs – Cubic Feet Per Second (28320 cumecs or Cubic Meters per second) of water[i]. Three days later, in the evening of Tuesday, Sept 1, they closed most of the spillway gates, thus reducing releases from spillway to less than a tenth of the earlier figure. During these 3-4 days (Aug 29-Sept 1), massive quantities were released, upto 30 000 cumecs through spillways, and almost nothing before or after! It created massive flood disaster all along the downstream from Gaudeshwar to Chandod to Bharuch, but the Sardar Sarovar Project (SSP) authorities or the Gujarat government seem least bothered. It is high time people of Gujarat wake up and hold the SSP operators accountable for this man made disaster.

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 Heavy Downpour brings back nightmare memories of 2019 Chambal Scare

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.

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.

This is India’s wettest June 12 years, The Times of India reported on July 1, 2020. Agriculture Ministry Data shows that sowing is 68% higher at 31.56 m ha. The June rainfall was 202 mm in 2008, the rainfall this year is the highest since then. All four IMD regions (Northwest, Central, South, East & NE) have recorded surplus rainfall, the surplus is the highest in Central (30.5% surplus) and E-NE (15.7%) regions. North West India had the lowest surplus at 3.5%. IMD Head Mrutyunjay Mohapatra said that whole of India was covered by monsoon on June 26, 12 days ahead of the normal date of July 8.

State wise rainfall Three states had large excess rainfall (above 60% surplus rainfall), namely Bihar, Madhya Pradesh and Sikkim.

State wise rainfall Pre Monsoon 2020 & Post monsoon 2019

India Meteorological Department (IMD) divides a water year (June 1 to May 31) into four seasons: Monsoon: (June 1 to Sept 30), Post monsoon (Oct 1 to Dec 31), Winter (Jan 1 to Feb 28/9) and Pre Monsoon (March 1 to May 31). For rainfall during all these seasons, IMD’s hydro-meteorological website[i] provides a lot of data on daily basis, including daily district wise rainfall, state-wise, sub division wise and river wise daily rainfall maps among many other weekly, monthly and seasonal products. However, one problem with it is that none of this information is achieved. So if you missed seeing or downloading available data on any date, there is no way to look at it even next day. This is even true of the seasonal rainfall maps, unfortunately.

Most observers look at the monsoon rainfall data, which is clearly the most important season, without doubt. However, the rainfall in other seasons is also very important from a number of perspectives.

Here we are giving a detailed account of the pre-monsoon season rainfall that India received in the season just ended on May 31, 2020, including state wise, sub division wise, river wise and also district wise figures. Along with it, we also provide the figures of post monsoon figures for the just concluded water year. For the winter season (Jan-Feb 2020) we have only the figures for Jan 2020 since we missed downloading the Feb 2020 figures. We had already provided the monsoon 2019 figures through two blogs in October 2019[ii].
