Detailed Description

Cross-section geometry — faithful 1:1 port of legacy xsect.c.

All formulas, lookup tables, constants, and dispatch logic are direct translations from src/legacy/engine/xsect.c (SWMM 5.2.x). Table data comes from xsect_tables.hpp. Numerical parity with the legacy engine is verified shape-by-shape by tests/unit/engine/test_xsect_parity.cpp.

Field-name mapping (legacy TXsect -> XSectParams): yFull->y_full wMax->w_max ywMax->yw_max aFull->a_full rFull->r_full sFull->s_full sMax->s_max yBot->y_bot aBot->a_bot sBot->s_bot rBot->r_bot
