摘要

Plzen City, know also as the City of the world famous beer Pilsner Urquel, was heavily flooded during the catastrophic flood in August 2002. This accident was a major driving force to create mathematical models of the rivers of Plzen City. In general, a hydraulic mathematical model of a city is not an exception in the Czech Republic. However, the mathematical model of Plzen City, thanks to an extremely complicated river systems is a very special hydraulic case. The presented model covers the hydrological and hydraulic conditions of five river bodies and four junctions and their mutual interrelations, which were found as significant. The most interesting part of the Plzen model was a special calibration procedure applied on mathematical models and the simulation of a number of different scenario combinations. A global 1D+ mathematical model was created, covering more than 60 km of river network and a wide area of flood plain using MIKE 11 software. The central part of Plzen City was schematized into a 2D curvilinear mathematical model using MIKE 21C SW. The main official outputs of this project were: 1. flood maps 2. maps of depths, water levels and velocities 3. longitudinal and cross-sectional profiles with an indication of water levels 4. evaluated proposal of the flood protection plan of Plzen City 5. HTML documentation The case of Plzen City is also special thanks to its location downstream of the reservoir Hracholusky on the Mze River, which creates a hypothetical risk for Plzen City. That is why the simulation of the Hracholusky dam break was carried out. Last but not least, an important feature of this project was a special way of creating the project documentation in HTML format. The documentation allows not only the viewing and reading of all documents and drawings, but also the preparation of user specific composition of final results and the ability to print them directly to a predefined scale, having installed only Internet Explorer. The finished model is nowadays frequently used for flood protection evaluation and the authorization of flood plain activities.
