UV VIS4

UV_VIS4

Option to activate/deactivate horizontal, biharmonic viscosity of momentum. The bihamonic mixing of momentum can be applied along terrain-following or geopotential levels. In ROMS, the viscosity is derived from the horizontal divergence of the deviatory stress tensor (Wajsowicz, 1993).
