Numerical model of three-dimensional shallow water flow in the Xiamen waters

摘要

摘要: 基于Casulli的三维浅水模型,改进浅滩处理方法,并入简化的紊流闭合模型,形成完整的海洋动力学基本方程组,改进了紊流闭合模型的求解方法,动力学模拟结果与实测结果符合良好,海域中大量浅滩的干出与淹没的面积和位置与实际情况吻合良好.本模型是厦门海域海洋动力学理论研究中第一个完全的三维斜压潮流场模型,全部程序用FORTRAN语言独立开发和编写.

Abstract: Based on semi-implicit finite difference methods for three-dimensional shallow water flow by Casulli, et al.(1992), a system of complete ocean dynamic basic equations, which include the reduced turbulence closure model, is established.The simulation of flooding and drying of the tidal flats and the solution method of turbulence closure model are improved.The numerical results are in good agreement with the measured data.This is the first complete baroclinic dynamic model in Xiamen waters and all the procedures are developed independently in FORTRAN.
