Country Overview

1.1.1.WATER RESOURCES Most of the rivers flow west and south through the plains. There are five main drainage systems, which altogether cover two-thirds of the territory: -The Han River basin in the northwest, with an average runoff estimated at 19.4km³/year and a drainage area of 26,018km²; -The Kuem River basin in the west, with an average runoff estimated at 6.2km³/year and a drainage area of 9,810km²; -The Nag Dong River basin in the south, with an average runoff estimated at 13.9km³/year and a drainage area of 23,817km²; -The Seom Jin River basin in the south, with an average runoff estimated at 3.8km³/year and a drainage area of 4,897km²; -The Young San River basin in the south, with an average runoff estimated at 2.6km³/year and a drainage area of 3,371km². The total annual volume of surface runoff produced internally is estimated at 62.25km³, while internal groundwater resources amount to approximately 13.3km³. About 10.7km³ of groundwater resources constitute the base flow of the rivers. Some transboundary rivers cross the border with DPR Korea. By taking into account the annual discharge of the Han River in DPR Korea (19.4km³/year with a catchment basin four times that of the basin flow into the Republic of Korea), the inflow to the Republic of Korea from DPR Korea is estimated at 4.85km³/year. The total average surface water discharge in the Republic of Korea is therefore estimated at 67.1km³/year. Due to the intensive nature of the rainfall and the steeper natural channel slopes, about 37 per cent of the annual water resources are flood runoffs, concentrated in summer. Out of the 64.5km³ of river runoff, 47km³ run off in flooding time. The total renewable water resources are estimated at 69.7km³/year. During the last 50 years, a considerable effort has been made to regulate the course of rivers. Multipurpose river basin schemes have been developed for flood control, irrigation, community water supply and hydropower production. In 1997, there were 765 dams of over 15m in height. There are more than 18,000 small irrigation reservoirs. Man-made lakes account for 93 per cent of all lakes in the Republic of Korea. The water storage for dams and reservoirs totals 16.2km³.

1.1.2.WATER USE Major environmental problems are air pollution in large cities; acid rain; water pollution from the discharge of sewage and industrial effluents; and drift net fishing. Managing clean water in rivers and lakes has been a major environmental policy target in Korea. As a result, the Korean government has continuously increased investment in sewage treatment facilities, drainage systems and industrial waste water treatment facilities. Recently, the Korean government introduced comprehensive water management measures for the four major river streams. ‘The act relating to water resources in Han River and community support’ and the special act on Nakdong Rivers watershed management’ were enacted in 1999. Similar acts regulating the Geum River and Yeongsan River watersheds were enacted in 2000. Korea enforces stringent drinking water quality standards. As a result, the proportion of monitoring sites which exceeded drinking water standards more than once per year is 0.6 per cent at filtration plants, 0.4 per cent at taps, and 14.7 per cent at mineral spring spots.

1.2.WATER QUALITY, ECOSYSTEMS AND HUMAN HEALTH The main institutions involved in irrigation and drainage include the Ministry of Agriculture, Forestry and Fisheries (MAFF), the Federation of Farmland Improvement Association (FFIA), and the Water Users Associations (WUAs). The MAFF, through the Rural Development Bureau (RDB), is responsible for policy, planning and financing of all rural infrastructure projects, and for the supervision of local government institutions, the RDC, the FFIA, the FLIAs and the WUAs. The RDC is a semi-autonomous agency which carries out the planning, study, design, and supervision of rural infrastructure projects in the country and overseas; the execution of largescale agricultural development projects; the operation and maintenance (O&M) of the important facilities of large-scale agricultural development projects; and the provision of O&M training courses for FLIA staff as well as engineering and administrative training courses for its own staff. The FFIA is a public corporation which mainly carries out the planning, design, and supervision of farmland improvement projects for farmland consolidation as well as providing guidance on the operational improvement of FLIAs. There are 105 FLIAs in the country which are responsible for the O&M of public irrigation systems. WUAs are organized by the farmers for the O&M of small irrigation systems which are not included in FLIA systems. The small systems are constructed and/or rehabilitated by the government through the cities or the counties before being transferred to WUAs.
