Function Documentation

batchDistributeEvap()

void openswmm::climate::batchDistributeEvap	(	double	evap_rate,
		const double *	ponded_depth,
		double *	evap_out,
		int	n,
		double	dt
	)

Batch distribute evaporation to all subcatchments.

evap_out[i] = min(evap_rate, ponded_depth[i] / dt) This is a vectorisable clamp operation.

Parameters

evap_rate	Scalar evap rate (ft/sec).
ponded_depth	[in] Per-subcatchment ponded depth (ft).
evap_out	[out] Per-subcatchment actual evap rate (ft/sec).
n	Number of subcatchments.
dt	Timestep (seconds).

hargreaves()

double openswmm::climate::hargreaves	(	double	latitude,
		int	day_of_year,
		double	t_avg,
		double	t_range
	)

Compute Hargreaves evapotranspiration.

Parameters

latitude	Latitude (degrees).
day_of_year	Day of year (1-365).
t_avg	Average temperature (deg F).
t_range	Temperature range (deg F).

Returns

Evaporation rate (in/day for US, mm/day for SI).

updateDailyClimate()

void openswmm::climate::updateDailyClimate	(	ClimateState &	state,
		int	day_of_year,
		int	month
	)

Update daily climate state.

Parameters

state	[in/out] Climate state.
day_of_year	Day of year.
month	Month (0-11).
