BCWOS

BCWOS(self, volume, tru_tovt=0.01, trh_tovt=0.07)

Boundary condition for overtopping flow, based on empirical formulas from van der Meer et al. (2011) and Hughes et al. (2012).

Attributes

Name	Type	Description
volume	float	The to be simulated individual overtopping volume
u_peak	float	Peak flow velocity
h_peak	float	Peak flow thickness
t_ovt	float	The total time of the overtopping event
tru_tovt	float	Ratio between the time of upeak and the overtopping time (tovt) (default: 0.01)
trh_tovt	float	Ratio between the time of hpeak and the overtopping time (tovt) (default: 0.07)
coef	float	Coefficient optimized such that the integrated u(t) and h(t) equal the given volume

Methods

Name	Description
get_flow	Compute (h, u) for time t based on current or given coef.
optimize_flow	Optimize coefficient until time series of u(t) and h(t) match the given volume

get_flow

BCWOS.get_flow(t, coef=None)

Compute (h, u) for time t based on current or given coef.

Parameters

Name	Type	Description	Default
t	Union[float, np.ndarray]	Time as a float or array	required
coef	float	Coefficient, if None use the coefficient determined by the optimize_flow function (default: None)	None

Returns

Name	Type	Description
	np.ndarray	2D array with (h, u) for t

optimize_flow

BCWOS.optimize_flow()

Optimize coefficient until time series of u(t) and h(t) match the given volume

Returns

Name	Type	Description
	float	The optimized coefficient
