A study by the Central Water Commission (CWC), New Delhi, has concluded that the flood in Kerala was due to severe storm occurrences and the release from reservoirs had only a minor role in flood augmentation.
The report, which was prepared by the Hydrology (South) Directorate, Hydrological Studies Organisation of the CWC, stated that the flood was due to severe storm occurrences during August 8 to 9 and 15 to 17.
“The storm of August 15 to 17 resulted in heavy flooding in Periyar, Pampa, Chalakudy and Bharatapuzha sub-basins of Kerala. The rainfall during August 15 to 17 was almost comparable to the historical July 16 to 18, 1924 rainfall of Kerala, particularly in the Periyar, Pampa, Chalakudy and Bharatapuzha sub-basins,” according to the report released on Monday.
