This command generates the runoff hydrograph for every catch
basin, inflow hydrograph for every pipe at upstream and outflow
hydrograph for every pipe at downstream. If the sewer network uses
Rational method to calculate the peak flow, the runoff hydrograph
is calculated by Universal Rational method; otherwise, the runoff
hydrograph is calculated by SCS method. The storage-indication
method is used to route the inflow hydrograph through the whole
network.
Select Sewer Network Hydrographs from the Network menu in the Hydrology Module. The command reads the current active sewer network file and conducts the hydraulic computation. If the computation is successful, a dialog opens with the lists of inflow and outflow hydrographs identified by the structures and pipes. Select a runoff, inflow and outflow hydrograph and click on Display button to show the hydrographs in the Hydrograph dialog.
