Detailed Description

One infiltration specification — POD mirror of openswmm::twoD::Infil2DRow.

Parameters are POSITIONAL and in PROJECT UNITS, matching legacy [INFILTRATION] exactly:

method	p[0]	p[1]	p[2]	p[3]	p[4]
SWMM_INFIL2D_HORTON	f0	fmin	decay (1/hr)	dry_time (d)	Fmax
SWMM_INFIL2D_MOD_HORTON	f0	fmin	decay (1/hr)	dry_time (d)	Fmax
SWMM_INFIL2D_GREEN_AMPT	S suction	Ks	IMD	—	—
SWMM_INFIL2D_MOD_GREEN_AMPT	S suction	Ks	IMD	—	—
SWMM_INFIL2D_CURVE_NUMBER	CN	—	dry_time (d)	—	—
SWMM_INFIL2D_CONSTANT	rate	—	—	—	—

f0 / fmin / Ks / rate are in/hr (US) or mm/hr (SI); S and Fmax are in (US) or mm (SI). CURVE_NUMBER's p[1] is unused and ignored, matching the legacy column layout where the middle value is a no-op. Slots a method does not use are ignored; write 0.

Member Data Documentation

dest

int SWMM_Infil2DRow::dest

One of the SWMM_INFIL2D_DEST_* codes. Only SWMM_INFIL2D_DEST_LOST is accepted in this release (D-I4).

has_method

int SWMM_Infil2DRow::has_method

0 = NONE (the cell/tag has no infiltration model). When 0, every other field is meaningless and is ignored on write.

method

int SWMM_Infil2DRow::method

One of the SWMM_INFIL2D_* method codes.

p

double SWMM_Infil2DRow::p[SWMM_INFIL2D_MAX_PARAMS]

Positional parameters in PROJECT UNITS — see the table above.
