Less time for water to succeed in Delhi from Hathnikund

According to the officers of the Central Water Commission, this 12 months the water launched from the Hanthnikund barrage took much less time to succeed in Delhi. Its velocity was excessive most likely due to the encroachment of the floodplain leaving a constricted route for the water to move. High siltation elevating the riverbed will also be one other issue contributing to Delhi flooding with out rain.

Extreme rainfall in a brief span of time

Delhi witnessed excessive rain on Saturday and Sunday because the Capital recorded the wettest July day in 40 years. As recorded on Sunday at 8.30am, Delhi recorded 153 mm of rain. Kejriwal earlier mentioned Delhi withstood 100 mm of rain in 24 hours earlier. But Delhi’s techniques will not be ready to take such an enormous quantity of rain. If the identical quantity of rainfall occurred over days, the state of affairs wouldn’t have worsened.

“We noticed that the water released from the Hathnikund barrage took less time to reach Delhi compared to previous years. The main reason could be encroachment and siltation. Earlier, the water would have had more space to flow. Now, it passes through a constricted cross-section,” an official of the CWC mentioned. The water from the barrage at Yamunanagar in Haryana, which is round 180 kilometres from the nationwide capital, takes round two to a few days to succeed in Delhi.
