Maximum head
The level value associated with Maximum Flow, in Units (2.1.1.) (Page 162).
Index
Values
This represents the highest head level supported by the PMD and works in conjunction with
Maximum flow (2.13.4.3.) (Page 243) to define the highest point in the exponential curve.
Use it when the PMD requires a maximum head and flow reference point. This would include
Exponential, Palmer-Bowlus Flume, H-Flume, and Universal breakpoints.
Zero head
The distance above Empty (2.2.4.) (Page 170), in Units (2.1.1.) (Page 162) representing
zero head (and zero flow).
Index
Values
This feature can be used for most weirs and some flumes (e.g. Palmer-Bowlus) where the
zero reference is at a higher elevation than the channel bottom.
