Prismatic Open Channel property sheet
This window shows a diagram of a trapezoidal open channel, with text boxes in which the bottom width, side slopes and height can be entered or displayed. Asymmetric channels with different side slopes on each side can be accommodated. For vertical sides a side slope X1 or X2 equal to zero can be entered.
A check box allows you to provide a horizontal roof on this channel if you wish. If this is specified, the channel will act as a closed conduit should the water level exceed the specified height.
Below this are text boxes for entering the name of the channel, its length and roughness, and space for notes. To the right are text boxes for entry of the invert levels at the upstream and downstream ends of the channel and the slope.
In the menu that calls this box there is also the opportunity to display plots of cross-sections.
