Simulation and visualization of flood submergence based on MIKE FLOOD and ArcObjects

This paper takes the plain area of middle reaches of Liaohe River as the study object, and uses the hydrodynamic software MIKE FLOOD to simulate the submergence of levee-overflowing flood. Based on the result of simulation, a flood routing display module is developed by the use of GIS development component ArcObjects and visual programming language C#. The functions of this module include flood routing display, submergence information query and flood loss statistic. In flood season, this module can provide decision-making information for flood-control and disaster-relief.
