Three-dimensional Numerical Modeling of Wind-induced Flow and Mass Transport in Natural Lakes
Author : Xiaobo Chao, Yafei Jia and A. K. M. Azad Hossain
Wind stress is one of the most important driving forces for lake water movement. This paper presents the development and application of a three-dimensional numerical model for simulating the flow circulations induced by wind and associated mass transport in natural lakes. This model was developed based on CCHE3D hydrodynamic model. It is a finite element model utilizing a special method based on the collocation approach called the efficient element method. A parabolic distribution of vertical eddy viscosity was specified to analyze the wind-driven flow. The model was first validated using experimental measurements, then it was applied to simulate the wind-driven flow and mass transport in several natural lakes in USA, including a small oxbow lake in Mississippi delta, a flood inundation zone in Iowa during the Midwest flood 2008, and a large reservoir in Mississippi. The simulated results were compared with field measurements, and good agreements were obtained.
