Viscosity Coefficient == [ {1} | ]

(Optional)

Sets the viscosity coefficient. It is not recommended that a value other than 1 m2/s be used for the constant viscosity formulations. Smagorinsky factor is typically between 0.06 to 1.0 (Note: the value used by MIKE 21 is the square root of the value used by TUFLOW. RMA and TUFLOW use the same value.)

Viscosity Formulation == [ {CONSTANT} | SMAGORINSKY ]

(Optional)



Sets the viscosity formulation. Options are:
