ABSTRACT: To study the rainstorm waterlogging disaster
in Huinan, Pudong District, an urban waterlogging model coupled with the
rainfall runoff sub-model, underground network sub-model and the overland flow
sub-model has been set up by MIKE FLOOD. After the validation with the actual
reports of the waterlogging in Huinan on Oct. 8th, 2013, the model is adopted
to simulate the overland flood before and after Gongji Road Rain Pump works to
study the impact of Gongji Road Rain Pump on the waterlogging disaster. The
results are analyzed and the conclusions are obtained: when Gongji Road Rain
Pump runs, the total flooded area will significantly decrease to .49 km2, about
21%, meanwhile, the drowned duration will be shortened in 6 hours, ahead 10
hours. Therefore, Gongji Road Rain Pump can alleviate the waterlogging, but
some other measures are still needed to be taken to solve the waterlogging
disaster.
