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.
