In steep-slope building hydrology, shedding rainwater off the main roof field is only half of the hydraulic equation. The real test of an envelope’s drainage engineering occurs at the lowest horizontal boundary: the eave terminal plane. During peak cloudbursts across the Western Ghats, coastal plains, and southern river basins, precipitation rates regularly reach 100 to …
