Suggestion for output of results Simulations for discharge-sea level –scenarios HQ 250, 100, 50, 30 N 60 + 0.5, 1.0, 1.5, 2.0 m Water levels in main reach cross sections in every 12 hours Top levels of embankments included in the results Comments, suggestions? Shall I calculate the rest of the scenariosand deliver the results to VATT?
