Abstract
Abstract. With the increasing trend of water-related disasters such as floods and droughts resulting from climate change, the integrated management of water resources is gaining importance recently. Korea has worked towards preventing disasters caused by floods and droughts, managing water resources efficiently through the coordinated operation of river facilities such as dams, weirs, and agricultural reservoirs. This has been pursued to enable everyone to enjoy the benefits inherent to the utilization of water resources, by preserving functional rivers, improving their utility and reducing the degradation of water quality caused by floods and droughts. At the same time, coordinated activities are being conducted in multi-purpose dams, hydro-power dams, weirs, agricultural reservoirs and water use facilities (featuring a daily water intake of over 100 000 m3 day−1) with the purpose of monitoring the management of such facilities. This is being done to ensure the protection of public interest without acting as an obstacle to sound water management practices. During Flood Season, each facilities contain flood control capacity by limited operating level which determined by the Regulation Council in advance. Dam flood discharge decisions are approved through the flood forecasting and management of Flood Control Office due to minimize flood damage for both upstream and downstream. The operational plan is implemented through the council's predetermination while dry season for adequate quantity and distribution of water.
Highlights
The construction of dams in Korea was motivated by the main purposes of either water supply or power generation
Large-scale multi-purpose dams have been built continuously in order to meet the rapid increase of water demand, as well as to prevent flood damage, until the 1980’s
Dams are managed by different organizations depending on their original purpose such as water supply, flood control, or hydropower, Multi-purpose dams, domestic and industrial water dams are managed by the Ministry of Land, Infrastructure and Transport (K-water), hydropower dams by the Ministry of Knowledge Economy (Korea Hydro & Nuclear Power Co., Ltd.), and agricultural reservoirs by the Ministry
Summary
The construction of dams in Korea was motivated by the main purposes of either water supply or power generation. Large-scale multi-purpose dams have been built continuously in order to meet the rapid increase of water demand, as well as to prevent flood damage, until the 1980’s. Looking at the current status of the nation’s dams Fig. 1, there are seventeen multi-purpose dams, fourteen water supply dams, eight hydropower dams, and two flood control dams (excepting of estuary barrages, agricultural reservoirs, pumped-storage hydroelectricity etc.). Dams are managed (operated) by different organizations depending on their original purpose such as water supply, flood control, or hydropower, Multi-purpose dams, domestic and industrial water dams are managed by the Ministry of Land, Infrastructure and Transport (K-water), hydropower dams by the Ministry of Knowledge Economy (Korea Hydro & Nuclear Power Co., Ltd.), and agricultural reservoirs by the Ministry. Water supply dams are categorized into Taebaek region, Pohang region, Woonmoon, Ulsan region, Geoje region, Yeosu region, Pyunglim, etc
