Significance of the File
contains input data to control UNTRIM2 weir sections depending on model results at runtime. The advantage is that the model user is no longer forced to enter exact times of weir height changes before the start of the model run. Instead e.g. the waterlevel at a given observation point inside the model is able to start a change of weir height if this waterlevel exceeds or falls below a given threshold. As well the magnitude of the current velocity or the direction of the current velocity or the speed of waterlevel change or the difference of waterlevels or current magnitudes at two given observation points can be used to compare with thresholds. Additionally specific dates or times or weekdays can be used and differnet conditions can be combined logically (and or or connections).
File-Contents (in Catchwords)
Input Steering Data
- general input data (block General_Data)
- key "EPSG" : EPSG-Code of all horizontical coordinates in this file.
- key "Time_Zone" : Time zone of all times in this file.
- control data of one weir section (block Operational_Weir)
This block contains conditions and data necessary to control the height and change of height of one weir section. This block can be used multiple times. Different weir sections can use the same Operational_Weir block, if all weir sections should be controlled in the same way. Different weir sections have to use different Operational_Weir blocks, if they shuld be controlled in a different way. Different means, that the weir type (bottom_up or top_down) is different or the sill depth of the weir is different or the conditions to close and open the weir are different. The name of the weir is the description to identify the block from outside.
General Remarks
- While reading this steering data file the dictionary file op_weir_dico.dat will be automatically accessed in directory $PROGHOME/dic/ to support input.
