  user must agree to the given terms and
  conditions. The HEC-ResSim was developed at

• On the occasion of the Dispatchers' Games held in
  November 2008 at the premises of the Ohre 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, Brezová,
  Stanovice and Nechranice.
• This model was biuld in connection with the work
  on the grant project reg. n. 103/07/1620.

• Watershed setup

• Using ESRI Shapefile as a bacground map is
  possible to import selected lines as the stream
  objects of the watershed directly to the
  watershed model.
• And another watershed elements can be created

• The rules

• The management rules that are at disposal for the
  waterworks can be principally divided into
• The rules for the release function that can be
  defined for the resrvoirs as a whole, for the dam
  objels en masse, with the selection of priorities
  in their usage (e.g. the precedence of the water
  power plants) and understandably for the
  individual manageable spillways, outlets and
  take-offs (eventually their user-defined groups).
• The rules dependent on the flow rate in the given
  profile under the waterwork (the downstream
  control function), defined for the waterwork as a
  whole.
• The tandem operations ensuring optimalization in
  the capacity usage on the waterworks cascade.
• The rules for the extreme flood situations
  (Induced Surcharge).
• The rules dependent on the velocity of the
  changes in other data, for example inlet, outlet,
  movement of the water level.
• The management rules for pumping stations and
  power plants with the possibility of entering
  several levels of time harmonograms and other
  specific rules.
• The script-defined management rules. These can be
  designed above all for special procedures of the
  outlet control. ResSim 3.0 has been recently
  equipped with the script editor using the syntax
  of the Jython language.

• Conclusion
• At the conclusion, we can state that the
  mathematical model of the WMS of the Ohre 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.
