pydantic model rompy.swan.subcomponents.physics.GODA[source]#

DAM transmission of Goda/Seelig (1979).

DAM GODA [hgt] [alpha] [beta]

This option specified transmission coefficients dependent on the incident wave conditions at the obstacle and on the obstacle height (which may be submerged).

Examples

In [22]: from rompy.swan.subcomponents.physics import GODA

In [23]: transm = GODA(hgt=3.0)

In [24]: print(transm.render())
DAM GODA hgt=3.0

In [25]: transm = GODA(hgt=3.0, alpha=2.6, beta=0.15)

In [26]: print(transm.render())
DAM GODA hgt=3.0 alpha=2.6 beta=0.15
Fields:
field alpha: float | None = None#

coefficient determining the transmission coefficient for Goda’s transmission formula (SWAN default: 2.6)

field beta: float | None = None#

Another coefficient determining the transmission coefficient for Goda’s transmission formula (SWAN default: 0.15)

field hgt: float [Required]#

The elevation of the top of the obstacle above reference level (same reference level as for bottom etc.); use a negative value if the top is below that reference level

field model_type: Literal['goda', 'GODA'] = 'goda'#
