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.

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concluded SW Monsoon 2019 (June-Sept 2019, though the monsoon started withdrawing only on Oct 9 and has not yet fully withdrawn from across India as I write this on Oct 15 2019), like the way we have been doing for the last three years[i].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.

Homes in Deluge: Aftermath of Maharashtra Floods 2019

Photo-blog 1

August 2019 Floods in Sangli and Kolhapur districts of Maharashtra have been historic. River levels washed away all  past records many times over. New High Flood Levels (HFL) were reached multiple times at multiple places both in Sangli and Kolhapur. These districts, which form the fertile Black Cotton Soil belt of Maharashtra, are the floodplains of mighty rivers of the Krishna Basin: Krishna, Koyna, Warna, Panchaganga, Tarli, Urmodi, Dudhganga, Hiranyakeshi etc.

On the 8th August, Krishna breached its HFL: Highest Flood Level at two places in Maharashtra (Kurundwad and Arjunwad). On the same day, Warna and Panchaganga too crossed their HFLs at two places: Samdoli and Terwad (Kolhapur). Continue reading “Homes in Deluge: Aftermath of Maharashtra Floods 2019”

More bad water news: 2018 Post monsoon rains 44% below normal

Even as large parts of India are facing drought, following deficit North West Monsoon, there is more bad news that farmers already know and experience. The rainfall in the three post monsoon months, from Oct 1 to Dec 31, 2018 at all India level has been 71.2 mm, which is 44% below normal rainfall of 127.2 mm. While the quantum of rainfall in these months is not expected to be high except in some South Indian areas, it is crucial for providing life saving and life sustaining moisture for the Rabi crop. It was particularly important since the second half of the South West monsoon was significantly below normal in large parts of Central and South India[i]. These same areas are experiences biggest deficits in Oct-Dec rains. Continue reading “More bad water news: 2018 Post monsoon rains 44% below normal”

India’s most important season from water point of view, the June-Sept South West Monsoon has just ended officially on Sept 30, 2018. India Meteorological Department (IMD) reported that India received 804 mm rainfall in these four months of monsoon 2018, compared to normal rainfall of 887.5 mm.
