Setup of Hydraulical Part of Model
• Setup of important valey obstruction
Güssing am 31.5./1.6.2011
• Setup of links
• Setup of cross profiles
• Setup of floodplain chanels
• Setup of river net - basic branches
• Final setup in network editor view.

Hydrological Model
• The qualityof calibration is depend on quality of input data.
• Daily precipitation can’t catch the short events so some of the peaks are missing in results of calibration
Güssing am 31.5./1.6.2011
• The optimal is to have 3-4 station for catchment in case we don’t have them is preferable to calibrate bigger parts of catchments together
• Calibration of very small catchment is not suitable for future system running as well

Conclusion: The calculated difference between Baltic leveling system (Bulgaria) and Leveling system in Turkey is 0,526 m in the border area. This difference may be valid for the area around Edirne.
