Member Function Documentation

◆ computeBuildup()

void openswmm::landuse::LanduseSolver::computeBuildup	(	SurfaceQualitySoA &	sq,
		const double *	area,
		const double *	curb_length,
		double	dt,
		int	n_subcatch
	)

Batch compute buildup for all subcatchments.

For each (subcatch, pollutant):

Convert current buildup to equivalent days (inverse function)
Add timestep: days += dt / 86400
Recompute buildup mass (forward function) All three steps are vectorisable (pow/exp/division).

◆ computeWashoff()

void openswmm::landuse::LanduseSolver::computeWashoff	(	SurfaceQualitySoA &	sq,
		const double *	runoff,
		const double *	area,
		int	n_subcatch
	)

Batch compute washoff for all subcatchments.

For each (subcatch, pollutant): EMC: conc = coeff (constant — trivially vectorisable) Exponential: conc = k * Q^n * B / (Q * A) (vectorisable) Rating: conc = k * (Q*A)^(n-1) (vectorisable)

◆ init()

void openswmm::landuse::LanduseSolver::init	(	int	n_landuses,
		int	n_pollutants
	)
