Fig. 4 Web interface of a reservoir monitoring system in Germany (source: fluggs.wupperverband.de) The ROPES interface is highly customizable and designed to be able to mimic the control interface that the operator uses for actual operation. This also means that the interface visible to the trainee only exposes those variables and controls that he would be able to access during actual operation. So, depending on the system being simulated, the interface may only display a few simple variables such as reservoir water level and the status of the gates. Or, when simulating more complex systems equipped with more monitoring equipment, the displayed variables may also include measurements from across the catchment, as well as other information such as current demand values or even forecasts. A second interface, only visible to the trainer or supervisor, acts as an administrative interface and allows the trainer to access all variables of the simulated system. With this information, the trainer is able to intervene in the trainee’s decision-making while the simulation is still ongoing, if necessary. Ordinarily, however, the second interface is only used to review the trainee’s decisions and their effects on the system in the review phase after the simulation has been completed. 4.1. SIMULATION ENGINE ROPES uses the software Talsim-NG as the backend for running the simulations. Talsim-NG was developed by SYDRO and has been proven and tested as a simulation tool for reservoir operation, rainfall-runoff calculation and flood routing both in planning stages and in real-time operation for more than 15 years. 415
