River Wise Rainfall in Monsoon 2017

India’s most important season, the June-Sept South West Monsoon has just ended officially on Sept 30, 2017. India Meteorological Department (IMD) reported that India received 841.3 mm rainfall in these four months of monsoon 2017, compared to normal rainfall of 887.5 mm. So Monsoon 2017 rainfall was 5.2% below normal.

The standard dominating reporting of monsoon rainfall figures in India is either state wise or sub division wise[i]. Accordingly, IMD reported that 25 sub divisions reported normal rainfall, 5 sub divisions[ii] reported excess rainfall and six sub divisions[iii] reported deficit rainfall, as can be seen from accompanying IMD sub division wise map of 2017 monsoon rainfall figures.

Welcome development: River basin wise rainfall maps from IMD!

We have noticed during just concluded South West monsoon season that IMD (India Meteorological Department) has started a new and welcome feature in rainfall data reporting[i]. The Data is available in maps, on daily, weekly and seasonal basis. We are not sure when this practice started, we noticed it only during 2016 monsoon season.

This is most welcome development, since getting rainfall data at basin level is most appropriate and useful, since basin is the hydrological unit that will experience the impact of rainfall or lack of rainfall in the basin, in form of floods or droughts. It can also be very useful for flood forecasting and preparedness, among many other uses. We hope IMD will develop and refine this further.

In each map, the actual rainfall for the given period is given for each basin, as also the normal rainfall & % departure from normal. Usual colour code is used to show the basin as blue if rainfall is more than 120% of normal rainfall, green if rainfall is 81-119 %, brown if rainfall is 60-80% of normal and yellow if rainfall is below 60% of normal rainfall.
