Control Operation Official Statements include principles and proceedings of distribution of
necessary duties, responsibilities, supervisions, and coordination among the pertinent organizations

As for Non-Structural Measures, DSI Regional Directorates prepare and update Regional Flood
Plans based on river basins studies and water storage circumstances in the river basins. Then, they
