Dam remediation decision support system
The sealing of underground karst conduits under the “Višegrad” dam was a very complex process, which required continuous monitoring and control. The goal of this capital project, financed by the World Bank, was to fill the conduits with granular material and concrete. In order to monitor the configuration of karst conduits during the remediation and to propose daily actions, we have developed a comprehensive mathematical model.
This complex multi-model consists of three models: (1) the hydraulic model of karst groundwater flow; (2) the model of solute transport and (3) the model of granular material transport and sedimentation. Parameters of the modeled conduits were estimated so that the model results fit the measurements. The estimation was performed using multi-objective evolutionary algorithms on distributed computing environment.
