Detailed Description

Cross-section lookup tables — translated from legacy xsect.dat.

All values are copied exactly from src/legacy/engine/xsect.dat (SWMM 5.2.1, Build 5.2.1, 08/01/22). No values have been rounded or modified. The Amax[] array is from src/legacy/engine/xsect.c.

Tables use the naming convention: A_xxx = area/fullarea vs depth/fulldepth Y_xxx = depth/fulldepth vs area/fullarea W_xxx = width/maxwidth vs depth/fulldepth R_xxx = hydrad/hydradfull vs depth/fulldepth S_xxx = sectionfactor/sectionfactorfull vs area/areafull

Note

INTERNAL HEADER — not installed. Used by XSection.cpp and XSectBatch.cpp.
