HYDRODYNAMIC 2D MODEL OF THE CITY CENTRE HYDROSYSTEM OF THE CITY OF WROCŁAW AND ITS FLOOD CAPACITY ANALYSIS

摘要

Aim of the study:Flood conveyance analysis of the Hydrosystem of the Wrocław City.Material and methods:Use of the hydrodynamic numerical model MIKE21. Use of the measurement data of the historic floods.Results and conclusions:Both the flow partitioning among the system channels, water levels and flow velocities were depicted and analyzed to bring a clear picture of the system conveyance capacity as well as to bring the effect of modernization into light. In addition, the peak discharge for a catastrophic flood of 1997 has been evaluated.
