Here are five reasons that led to Delhi’s monsoon mess:Are Delhi-NCR’s waterways lost? Why aren’t they cleaned before every monsoon?” asked Shashank Shekhar, assistant professor, department of geology, Delhi University. While Safdarjung, Palam and Delhi Ridge weather stations recorded 5.5 cm; 8.8 cm and 7.7 cm of rainfall, respectively, on Wednesday. For example, for one unit of rain, a paved area will generate 95% of run-off, as compared to 50% for a natural area. This has led to a massive uptick in the volume of water that needs to be drained in the national capital.
