On the occasion of the Dispatchers' Games held in November 2008 at the premises of the Ohře River Basin Authority, state enterprise, in Chomutov, the model of the water management system control created at the Czech University of Life Sciences was tested. The model was formed with the help of the HEC-ResSim 3.0 program which is currently used, among others, for the students instruction in the lectures on hydroinformatics

For the sake of the presentation, the real historical flood data were selected, with the flood passage somewhat increased, in order to demonstrate enhanced impact at the flood region. The result of the attempt ought to have been to define the most effective flood control by means of the appropriate operations on the reservoir system Skalka, Jesenice, Horka, Březová, Stanovice and Nechranice.

This model was biuld in connection with the work on the grant project reg. n. 103/07/1620.

HEC-ResSim 3.0Using ESRI Shape–file as a bacground map is possible to import selected lines as the stream objects of the watershed directly to the watershed model.

The Result:

At the conclusion we can state that the mathematical model of the WMS of the Ohře river basin performed by the HEC-ResSim 3.0 program fully proved its functionality and practical usability. HEC-ResSim proved to be a very productive modelling instrument with the perspective of a wide use, and freely accessible at that. It was found suitable for the development and research purposes and for the school instruction on hydroinformatics.

THANK YOU FOR YOUR ATTENTION.
