1 Güssing am 31.5/1.6.2011 PRORAAB(A) Hochwasserprognosemodell RAAB Rába előrejelző modell Dieses Projekt wird von der Europäischen Union kofinanziert Az Európai Unió társfinanszírozásával megvalósuló projekt. Hungarian Part of Raba Model development Dr. Michal Veverka

2 Güssing am 31.5./1.6.2011 RAAB(A)…. Flood Forecasting model

3 FFS Development of Hungarian Part Güssing am 31.5./1.6.2011 pointspoints 10891 BranchesBranches 87 15rek ProfilesBoundarty conditionsProfilesBoundarty conditions setup for calibration of HU partsetup of merged model Points 1089121900.00 Branches total 87120.00 River Branches Parts19.0044.00 Branches - Connection Links66.0069.00 Flood Plain Branches7.00 Boundary Conditions15.0034.00

4 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.

5 Calibration example Güssing am 31.5./1.6.2011 Ragyogohit

6 Calibration – Hydrologicall Model Güssing am 31.5./1.6.2011 Setup of roughness based on field inspection CORINE Landuse Methodology Meteo data (rainfall and evap, teper,) Hydro data Q

7 Hydrological Model The qualityof calibration is depend on quality of input data. Daily precipitation cant 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 dont 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 RR1 RR2 RR3 RR4 RR5 RR6 RR7 RR8 RR9 RR1 0 RR1 1 RR1 2

8 Merging of Forecasting Models AT -HU Güssing am 31.5./1.6.2011 Border – geograficall probles

9 Elevation problems Güssing am 31.5./1.6.2011 A Austrian cross profile B - Real distance between profiles Hungarian cross profile C A – Real elevation difference B – Real distance between profiles C – The difference between Hu and Au reference level B (m)C (m) mistake in slope % 5000.50.001 2000.50.0025 1000.50.005 Merging of Forecasting Models AT -HU

10 Elevation problems – TR – BG experience Güssing am 31.5./1.6.2011 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.
