Simulation of flow discharge on Danube River

Petre Bazavan

Abstract


River flow predictions are needed in many water resources management.
This paper presents the results of a numerical method based on Saint-Venant equations to predict flood events on the Danube sector between Iron Gates I and Iron Gates II. A McCormack scheme is used in conjunction with time step control and adaptive roughness coefficient based on water depth and discharge ratio in order to simulate rapid changes of discharge at Iron Gates I and estimate the pick flow at Iron Gates II. The study was supported by the ENVISION project under the seventh European framework programme and benefited from data provided by Hidroelectrica Romanian company.
