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.
