Four Major River

We support water policies for conservation of water quality and aquatic ecosystem in four major river watersheds by

  • operating nationwide observation network for water quality and sediment (to support climate change policy).
  • conducting preventive water quality management through algal bloom alarm systems and water quality forecasting systems.
  • measuring mainstream and tributary ows for Total Maximum Daily Load (TMDL).
  • conducting comprehensive monitoring and studies of control measures for nonpoint source pollution (e.g. characteristics of rainfall runoff by land use).
  • conducting monitoring of hazardous pollutant pathways in tributaries of the river basin.
  • operating observation networks for radioactive substances in public waters.
  • conducting monitoring of aquatic ecosystems at weirs on the four major rivers.
  • investigating the aquatic environment and ecosystem in the four major rivers.
  • promoting Basic Environmental Survey Project to improve water quality and aquatic ecosystem health in the four major rivers.
  • promoting investigation and research projects on pressing environmental issues by watershed.
  • responding to contamination accidents and environmental problems through an immediate monitoring system.
