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.Continue reading “District wise rainfall in June-Aug 2020 in India”
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.

A life-giving organism can not be controversial, but in India rivers that ought to be naturally free-flowing have been made controversial by policy makers and politicians over the past few decades. Narmada is one of them! Continue reading “Book Review: Narmada Valley’s gripping story!”
Here we present the rainfall figures from India Meteorological Department in the just concluded month of June 2020, the first month of SW Monsoon 2020. The overall rainfall at all India level in June 2020 was 196.2 mm, 18% above normal rainfall in the month at 166.9 mm. It was 33% deficit last year.
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. Eight states/UTs (Union Territories) had excess rainfall (20-59% surplus): Assam, Meghalaya, UP, Chhattisgarh, Maharashtra, Telangana, Andhra Pradesh & Andaman and Nicobar. Nine had deficient rainfall (20-59% deficit): Lakshadweep, Mizoram, Manipur, J&K, Ladakh, Himachal Pradesh, Delhi, Dadar & Nagar Haveli. Rest of India had Normal Rainfall.

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 archived. 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].

Narmada is a sacred river originating in the Maikal Hills of central India from a place called Amarkantak. Parikrama is a Sanskrit word derived from the root ‘pari‘ meaning around and ‘krama‘ meaning going. And hence, Narmada Parikrama means circumambulating the river. This is a spiritual/religious tradition of the Hindus existing from centuries wherein pilgrims start walking from any point along the river after collecting Narmadaji’s water in a vial and start walking with the river to their right.
If a person has started from the north bank, they’d walk upstream to the origin of the river in Amarkantak, cross over from beyond the origin point, come to the south bank and walk downstream till the point where the river meets the ocean in south Gujarat. From here, pilgrims board a large boat for an estimated four to seven hours to cross over and reach back to north bank at a place called Mithi Talai. From here, the pilgrim starts walking upstream again to arrive again at the point where they started from. At the end of the journey, pilgrims go to the super sacred Omkareshwar which is one of the 12 ‘Jyotirlingas’ and also a river island which means a person cannot go to this point during the parikrama. One of the rules of the walk is that a person cannot cross over the river and go to the other bank or in the middle. At Omkareshwar, the pilgrim pours back the water that she collected in a vial when she started the walk and completes the parikrama.

Most of the Indian states have been facing multiple environmental issues on account of unsustainable riverbed mining activities. Mechanized excavation, nexus between politicians-administration-mafia, violent attacks on people have become common features of the illegal sand trade across the country. The rampant mining of natural resource is also severely impacting rivers, wildlife and groundwater table. And the state of Gujarat is no exception to all this as shows the year end overview.
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.
