Can HydroCAD calculate the Hydraulic Grade Line (HGL) ?

Determining the HGL traditionally involves a steady-state analysis, with the entire drainage system at equilibrium. Since hydrograph routing models are handling a time-varying flow, there is no single HGL for the system. However, the peak elevation calculated at each node can be used as the effective HGL.
