Abstract
ABSTRACT Zhong, G.H.; Liu, S.G.; Han, C., and Huang, W., 2014. Urban flood mapping for Jiaxing City based on hydrodynamic modeling and GIS analysis. Under the climate change, extreme precipitation has been increasing dramatically, accompanied by more severe floods. The low-lying coastal areas, in particular, those due to the frequent storm surges, are suffering from heavier floods. Recently, in addition to the traditional engineering measures, researchers are exploring non-engineering measures to mitigate damages caused by flood. Development of flood risk maps which assess the vulnerable zones in the floodable (i.e. flood prone) areas is one of these non-engineering measures. Jiaxing City, a key central city in the Yangtze River Delta Area, China, is the study area in this research. Considering its particular features such as low-lying topography, dense rivers, numerous dyked areas, river flow affected by the tides and intensive human activities, a coupling hydrodynamic model of one-dimensional and two-di...
