| A team of CPMU, CWC officials and KSEB officials inspected the Poringalkuthu Dam in Kerala on 27th September 2018 to review the on-going rehabilitation works under DRIP as well as to assess the impact of the unprecedented flood in August 2018. Proingalkuthu dam is 36.90m high and 365.76m long masonry gravity dam, built across the Chalakudya River. Its construction was completed in 1957. The Sluice openings are capable of passing the design flood of 2265 cumec at FRL. The dam was overtopped during Kerala flood of August 2018 on account of excessive precipitation in the catchment area resulting into heavy inflow about 3000 cumec. The severity of overtopping was very extreme as the water level rose approximately about 2-2.5m above dam top and lasted about 24-26 hours. Some of the damaged portions of the left training wall, dam top road near left bank portions of the left training wall, dam top road near left bank portion and scoured dam toe can be seen in the above photographs. |
