In this study we developed an integrated turbidity management system to support the
operation for effective turbid water management. The decision-making system includes various
models for prediction of turbid water inflow, effective reservoir operation using the selective withdrawal facility, analysis of turbid water discharge in the downstream. The system is supported by the intensive monitoring devices installed in the upstream rivers, reservoirs, and downstream rivers. It is expected that the operation with the system developed in this study will help manage turbid water problems in the reservoirs and the downstream through timely removal of high turbid water flowing into the reservoir during heavy rainstorm considering various conditions of downstream areas.
