Abstract: Water leakage under Višegrad dam was observed already in the first years of its exploitation. Further intensification of this phenomenon could have caused a variety of adverse effects, so it was necessary to repair leakage by incorporating granulated materials into underground cavities. However, the sealing of underground karst conduits is a very complex process, which requires continuous monitoring and control. In order to make the right decisions during the remediation, we have developed a software platform able to evaluate the effects of the implemented technological processes in near real-time and to help decision-makers in planning their future activities. The platform relies on numerical models of hydraulics and mass transport, which are used to calculate piezometric levels, flow rates, and tracer concentrations for an assumed system configuration and under given boundary conditions. The data obtained from the measurement system were periodically in an automated manner assimilated into numerical model in order to obtain the model states that best comply with the reality. To secure that simulation results are deployed in a reasonable timeframe, the platform is designed in the way that enables running all the calculations and data assimilation on a high-performance computing infrastructure.
