Abstract

Cut-off channels and floodways are used as simple flood control measures in rivers and bodies of water to mitigate the detriments brought about by flooding. Most flooding analyses are done using the intensity of rainfall as basis for the occurrence of flooding and the morphology of a stream or channel is seldom investigated. Estero de Tripa de Gallina in South Manila is common source of flooding due to the frequent rainfall and drainage problems in the creek. However, the stream has a point of confluence where a discharge coming from another catchment joins the flow of the stream. And, with the help of computer simulation and modeling using XPSwmm 2012, the channel, with the connected network, was analyzed using extreme rainfall events with return periods 2 years and 100 years. Different configurations of a weir were installed and the change in runoff for the downstream nodes and the point of bifurcation were observed. The installation of weir as a control structure resulted to a decrease of 81.8% in the downstream flow for the 100-year return period, and 69.4% for the 2-year return period.
