During the last decade, variety of water associated problems such as more
frequent and severe droughts and floods, conflicts between stakeholders for
water use, degradation of ecosystems due to water pollution have made the
serious burden undertaken by governments and local residents in Korea. In order
to resolve these problems, advanced tools for basin-wide Integrated Water
Resources Management (IWRM) allowing more efficient and sustainable
operation of existing water resources facilities are urgently required (Ko & Chung,
2002, Ko, 2004, Ko & Kim, 2008). The new basin-wide IWRM approach seeks
environmental sustainability, equity, and economic efficiency in water allocation
and operation through integrated considerations of the mutual interests of water
stakeholders, the relationship of water quantity and quality, and the relationship
of water and adjacent land use. In this paper, the technical framework for a longterm
national research project to develop the Integrated Real-time Water
Management System (IRWMS), a decision support tool, for integrated river basin
water management will be introduced.
