Schedule File

The first line of the schedule file specifies the parameter nSections, the number of periods in the schedule where weir height should change. Each subsequent line specifies one section, which includes the starting and ending time of the period, and ZF, the weir height at the end of the period. All weir heights are interpolated linearly in time during the change in height. The entire schedule file applies to all weir nodes that reference the schedule file from within the Time Varying Weirs input file.

Use some combination of the following time parameters on each line to specify the start and end of the weir height change period, relative to the start of the schedule.

TimeStartDay – number of days since the beginning of the schedule when the weir height starts to change
TimeStartHour – number of hours since the beginning of the schedule when the weir height starts to change
TimeStartMin – number of minutes since the beginning of the schedule when the weir height starts to change
TimeStartSec – number of seconds since the beginning of the schedule when the weir height starts to change

TimeEndDay – number of days since the beginning of the schedule when the change in weir height is complete
TimeEndHour – number of hours since the beginning of the schedule when the change in weir height is complete
TimeEndMin – number of minutes since the beginning of the schedule when the change in weir height is complete
TimeEndSec – number of seconds since the beginning of the schedule when the change in weir height is complete

ZF – The weir elevation at the end of this change. Generalized values are available to make it more convenient to apply a single schedule file to many weir nodes. These shortcut values are as follows

-99990 – Make the final weir height equal to the mesh bathy/topo elevation at that node
-99991 – Add a specified amount (specified elsewhere on this line as Delta) to the weir height
-99992 – Subtract a specified amount (specified elsewhere on this line as Delta) from the weir height
–99993 – Make the final weir height equal to the original weir height as specified in the fort.14 file (useful for ending a schedule file that will be repeated).

Delta – Add/Subtract this value from the current elevation of the weir when using -99991 or -99992 for ZF.
