Simple Junctions are typically used to connect two open connections, such as the Rectangular Channel, Trapezoidal Channel and Triangular Channel connection types, where there is a change in the dimensions or slope of the channel or where an open connections meets a Pipe Connection connection. The Simple Junction may also be used for pipe joins without a manhole or for joining other Connection types.
Special rules apply to Simple Junctions during analysis. The levels are inferred from joining connections where these exist, where Simple Junctions are used to join Connections without levels flow is assumed to pass straight through unless restricted by an Outlet.
Name – Displays the name of the manhole.
Part Family – Select the part family associated with this manhole. For more information, see Part Families.
Dimensions
Junction Type – Select either Simple Junction or Manhole from the drop-down list.
Easting – The easting coordinate at the centre of the icon on Plan.
Northing – The northing coordinate at the centre of the icon on Plan.
Bend Loss – The loss coefficient associated with energy losses that occur when flow enters a junction and then exits through an outgoing connection at a different angle. For more information, see Analysis of Junctions and Connections.
