Fig. 4: Change in September precipitation after river-interlinking.
From: River interlinking alters land-atmosphere feedback and changes the Indian summer monsoon
a Percentage change in mean daily precipitation between WRF irrigation run (IRR) and control run (CTL) (IRR-CTL) for the month of September. Hatch lines mark regions where the difference was found statistically significant at 90% confidence tested on 660 data points. b Violin plots of percentage change for all years in mean September rainfall for regions marked in (a). Median and mean change for all years are represented by red and black horizontal lines, respectively. Median percentage change is also written with the name of each region. There is a significant reduction in September precipitation of up to 12% in central (state of Madhya Pradesh), eastern (states of Odisha and Chhattisgarh), northern (state of Uttarakhand in western Himalaya), and western arid region (states of Rajasthan and Gujarat) of India.
