Aiming at the problems that the existing methods have weak visualization effect and difficult interaction in wind wave dynamic simulation, this paper presents a dynamic simulation method coupling wind wave model with WebGL. The threedimensional scene of wind wave is drawn based on WebGL technology. The dynamic simulation of wind wave in small wetlands is realized in different conditions with Three.js mainstream graphics library and particle system. The experimental results show that the dynamic simulation method is feasible and robust, provides users with more immersive interactive experience and realistic simulation scenes, and also provides new decision support for wetland management.
