getInflow()

double openswmm::roadway::getInflow	(	double	dir,
		double	h_road,
		double	h1,
		double	h2,
		double	cd_user,
		bool	si,
		double	road_width,
		int	road_surf,
		double	length,
		double &	dqdh,
		double &	depth )

legacy roadway_getInflow: flow across a roadway weir.

Parameters

	dir	Flow direction (+1 or -1); the heads are already swapped for reverse flow.
	h_road	Road (crest) elevation (ft).
	h1	Upstream head (ft).
	h2	Downstream head (ft).
	cd_user	The weir's discharge coefficient as written (Cd for cfs; divided by 0.552 on an SI project).
	si	True on an SI project.
	road_width	Road width across the flow (ft); 0 = unknown.
	road_surf	SURFACE_PAVED / SURFACE_GRAVEL / SURFACE_NONE.
	length	Weir length (the section's wMax, ft).
[out]	dqdh	dQ/dH (ft2/s), 0 when dry.
[out]	depth	Link depth: max(h1 - h_road, 0).

Returns

dir * q (cfs).
