LANS-alpha turbulence modeling for coastal sea: an application to Alderney Race

this repository provides the source code based on mars3d model code (lazure and dumas, 2008), with modifications for the lans-alpha implementation (hecht et al, 2008).model outputs of an application on the alderney race are also provided. simulations with and without lans-alpha have been performed for two days (29-30 september 2017), with model configurations at two different horizontal resolutions (120 and 30 meters). two cases have been considered for the vertical mixing parametrization, with the use of the k-epsilon turbulent closure and a constant vertical viscosity of 0.2 m2.s-1 .

本仓库提供了基于Mars3d模型代码（Lazure和Dumas，2008年）的源代码，并对Lans-alpha实现（Hecht等人，2008年）进行了修改。同时，还提供了在Alderney竞赛中的应用模型输出。对是否采用Lans-alpha进行了两天（2017年9月29日至30日）的模拟，模型配置在两个不同的水平分辨率（120米和30米）下进行。对于垂直混合参数化考虑了两种情况，使用了k-epsilon湍流封闭和0.2 m².s⁻¹的恒定垂直粘度。
