—This paper deals with the hydraulic analysis of
storm diversion system (SDS) of Begunbari-Hatirjheel lake
project of Dhaka city, Bangladesh. For analyzing behavior of
pipe system hydraulic modeling software, Sewer CAD has been
used. Analysis has been done for both dry season and wet
weather flow conditions. Different gated conditions such as, full
and partially full pipe flow have also been considered in
hydraulic analysis. Inflow storm peak discharge has been
calculated using rational method. Dry weather condition has
been analyzed using design data which represents the present
operating condition of diversion system. It reveals that the wet
season peak flows in pipes undergo highly supercritical with
high turbulence and backflow. It is hoped that the storm flow
hydraulic analysis presented in this paper will manifest an idea
about the post project flow behavior in the sewer for both
extreme and minimum flow condition.
