ABSTRACT = {Considering the accidents of ships for dangerous chemicals transportation in 
inland rivers, a numerical method for the simulation of the leakage and diffusion 
processes of dangerous chemicals in inland rivers is proposed in this paper. Geographic 
information, such as rivers and buildings in the model, is obtained through Google Earth 
and structures of rivers and buildings are described by Auto CAD. In addition, the Fluent 
is adopted to simulate the leakage and diffusion processes of the dangerous chemicals
where the standard <i>k-ε</i> model is used to calculate the turbulent flow. Considering the 
interaction between chemicals and water, the VOF method is used to describe the leakage, 
drift and diffusion process of dangerous chemicals groups on the water surface. Taking a 
section of the Yangtze River as an example, the leakage and diffusion processes from a 
ship carrying 3,000 tons of low-solubility and low-volatile dangerous chemicals are 
studied, and the characteristics of leakage and diffusion are analyzed in detail. During the 
simulation, the area of the maximum group of leaked dangerous chemicals reaches up to
about 1800 m<sup>2</sup>
, and the number reaches up to 45. Furthermore, the influence of density, 
viscosity, water velocity and leakage velocity on the leakage and diffusion processes is
investigated in this paper.},
