CWC Guidelines for Aqueducts Design Flood Period

As per the Central Water Commission (CWC) guidelines, the design flood for aqueducts should be selected based on a specified time period. The design flood is a critical parameter in ensuring the structural integrity and safety of aqueducts during flood events.

As per CWC guidelines to select floods:

(a) For spillways for major and medium projects with storage more than 60 Mm³ recommended design flood is either probable maximum flood or flood frequency method with return period of 1000 years.

(b) For permanent barrages and minor dams with capacity less than 60 Mm³ recommended design flood is standard probable flood (or) flood with time period of 100 years whichever is higher.

(c) Aqueducts is recommended for a design flood for time period of 50 years.
