Detailed Description

Street / channel geometry seen by one inlet, in INTERNAL units.

Mirrors the file-scope block of legacy inlet.c (Sx, SL, Sw, a, W, T, n, Nsides, Tcrown, Beta, Qfactor, xsect) that getConduitGeometry() (inlet.c:1147-1196) fills. t (the flow spread) is an output of getFlowSpread() that later kernels read, exactly as legacy's shared T is.

Member Data Documentation

a

double openswmm::inlet::Geom::a = 0.0

Gutter depression (ft)

beta

double openswmm::inlet::Geom::beta = 0.0

1.486·√SL / n

n

double openswmm::inlet::Geom::n = 0.016

Manning's roughness.

nsides

int openswmm::inlet::Geom::nsides = 1

1- or 2-sided street

qfactor

double openswmm::inlet::Geom::qfactor = 0.0

Izzard's f in Q = f·T^2.67.

sl

double openswmm::inlet::Geom::sl = 0.0

Conduit longitudinal slope (fraction)

sw

double openswmm::inlet::Geom::sw = 0.01

Gutter + cross slope.

sx

double openswmm::inlet::Geom::sx = 0.01

Street cross slope (fraction)

t

double openswmm::inlet::Geom::t = 0.0

Top width of flow spread (ft) — set by getFlowSpread.

t_crown

double openswmm::inlet::Geom::t_crown = 100.0

Distance from curb to crown (ft)

w

double openswmm::inlet::Geom::w = 0.0

Gutter width (ft)

xs

const XSectParams* openswmm::inlet::Geom::xs = nullptr

Host conduit cross-section — non-null only for the DROP_* (channel) designs, whose grate kernel needs A(S)/Y(A)/W(Y) of the channel.
