History of the development of the hydrodynamic model of the open pit mine “Drmno”, Serbia

With the creation of a hydrodynamic model, the need for it usually ceases until some next moment when the model needs to be updated and used for the set task for the necessary project documentation or dedicated studies. It is relatively rare that almost every year the model is improved and used for forecast calculations. The paper presents the basic characteristics and development of the hydrodynamic model of the open pit mine “Drmno” for 25 years. This open pit mine is the second-largest mine in Serbia. At the time the model was made (1998), it was the largest and most complex model that was made in the former Yugoslavia. Also, advanced model calibration techniques were used for the first time in Serbia
