									A QUICK HEC-RAS BRIDGE TUTORIAL
14m Span at Station 527 of the Red Hill Class File
         (change discharge to 95m3/s)
14m Span at Station 527 of the Red Hill Class File
              (Plot Existing Conditions)
         14m Span at Station 527 of the Red Hill Class File
(Save a table to excel of output – add a channel shear stress column)
               14m Span at Station 527 of the Red Hill Class File
(Copy table to the clipboard to paste into EXCEL (or other graphing package for plotting)
14m Span at Station 527 of the Red Hill Class File
Lets centre the bridge so that the down stream face of the bridge is located at 528m
          – so the centre line of the bridge station will be located at 538m
                         (since we have a 20m wide bridge)
       We also need to add a new cross section at the upstream face of the bridge
(station 548m). To do this we are going to go into our cross section geometry editor for
    the section at 527m and copy this section to 548m and then adjust the elevations
Copy cross section 527m to 548
Adjust new cross section elevations so there is a constant slope
                 between sections 527 & 602
Add road deck
Add vertical abutments
Run the bridge configuration & view the profile
Copy table (that includes main channel shear stress) and past into Excel
REPEAT FOR OTHER BRIDGE SPANS
