Detailed Description

湖流模型

  

             

式中,h为水深;hb为湖床高程;u为x方向的水流速度;v为y方向的水流速度;g为重力加速度;ρ为水的密度(ρ=1000kg•m-3);f为Coriolis参数(f=2шsinφ),ш为地球旋转角速度(ш=2π/3600×24(s-1),φ是纬度(φ=29°);C为谢才参数η为湖床糙率;τsxτsy为水面风应力,τsx2ρaW2cosθ,τsy2ρaW2sinθ,ρa为空气密度(1.29kg·m-3),θ为风的方向角(等于135°),γ为风应力系数(γ2=0.0026),W为风速[W=6m·s-1(四级风),9m·s-1(五级风),12m·s-1(六级风)]。
