Namespaces
namespace	openswmm

namespace	openswmm::infil
	Native infiltration kernels with caller-managed accepted-step state. These methods mutate the supplied state immediately and provide no rollback, finite-input validation or failure status. Call once per accepted source step, or evaluate a private state copy for a trial. Internal rates/depths are ft/s/ft; initialization alone accepts project input units. Serialize shared state use.

Functions
void	openswmm::infil::horton_init (HortonState &state, double f0, double fmin, double decay, double regen, double Fmax, const SimulationOptions &opts)
	Convert authored Horton parameters and reset ordinary Horton history.

double	openswmm::infil::horton_getInfil (HortonState &state, double precip, double depth, double dt)
	Integrate exponential Horton capacity over one step with dry recovery.

double	openswmm::infil::modHorton_getInfil (HortonState &state, double precip, double depth, double dt)
	Advance the linear excess-infiltration Modified Horton model.

void	openswmm::infil::grnampt_init (GreenAmptState &state, double S, double Ks, double IMD, const SimulationOptions &opts)
	Convert authored Green-Ampt parameters and initialize the upper zone.

double	openswmm::infil::grnampt_getInfil (GreenAmptState &state, double precip, double depth, double dt, InfilModel model_type=InfilModel::GREEN_AMPT, double infil_factor=1.0, double recovery_factor=1.0)
	Advance saturated/unsaturated Green-Ampt history and compute actual infiltration.

void	openswmm::infil::curvenum_init (CurveNumState &state, double CN, double regen)
	Initialize Curve Number retention and all event-history fields.

double	openswmm::infil::curvenum_getInfil (CurveNumState &state, double precip, double depth, double dt, double recovery_factor=1.0)
	Advance SCS Curve Number event retention with ponded-water continuation.

double	openswmm::infil::constant_getInfil (double rate_ftsec, double precip, double depth, double dt)
	Return a stateless capacity bounded by available water.
