Study on Constructing Mathematical model of City-Flood and Numerical Simulation
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 5
Abstract
In this paper, it is suggested to natural phenomenon of rain-storm result in the accumulation disaster. Hypotheses proposed model based on physical background, variable selection coefficient convection - diffusion equation accurately described, and used the terrain function instead of convection - diffusion equation parameters term, comprehensive rainfall, drainage, infiltration and other related functions form a function matching the physical background. This article established mathematical model of urban flooding, using the finite element method, discussed related factors in detail. It could be combined with hydrodynamic and weather forecast. It could directly simulate and forecast the accumulation disaster and strengthen the ability for meteorological service. The importance of establishing the city-flood model is obvious.
