RoutePipe is used to route hydrographs in circular or rectangular pipes. It uses a simplified form of the RouteChannel input.
Only the pipe diameter or width and heights are required and only one Manning’s roughness coefficient is allowed.
The hydrologic object automatically resizes the pipe cross-section if the dimensions entered are not sufficient to accommodate the peak flow without surcharging.
