Recognizing a complexity of global water challenges, such as water shortage, water pollution, water-related disasters, and degradation of water environments, this study introduces the newly established concept and definition of water security and water security assessment framework based on the review of previous works on water security. In order to critically assess the situations of water security of each country, an water security assessment framework is employed highlighting the four core areas: 1) social equity; 2) economic efficiency; 3) environmental sustainability; and 4) resilience to water-related disasters. 28 Asian countries have been selected and evaluated for the level of water security, and as a consequence, Japan, Malaysia and South Korea demonstrate a high degree of water security whereas India, Pakistan and the Philippines show a relatively low level of water security. The significance of this study lies in clarifying weak areas in water security as well as suggesting the areas that should be improved for achieving sustainable water management.

In South Korea, 850 standard watersheds and 7,807 KRF catchment areas have been used as basic maps for water resources policy establishment, however it becomes necessary to set up new standard maps with a more appropriate scale for the integrated managements of surface water-groundwater as well as water quantity-quality in the era of integrated water management. Since groundwater has a slow flow velocity and also has 3-D flow properties compared to surface water, the sub-catchment size is more effective than the regional watershed for the evaluation of surface water-groundwater interaction. The KRF catchment area, which has averagely a smaller area than the standard watershed, is similar to the sub-catchment area that generally includes the first-order or second-order tributaries. Some KRF catchment areas, which are based on the surface reach, are too small or large in a wide plain or high mountain area. Therefore, it is necessary to revise the existing KRF area if being used as a unit area for integrated management of surface-water and groundwater. A unit watershed with a KRF area of about 5 to 15 km2 can be effective as a basic unit for water management of local government considering a tributary composition and the location of groundwater wells, and as well it can be used as a basic tool for water demand-supply evaluation, hydrological observation system establishment, judgment of groundwater permission through a total quantity management system, pollution assessment, and prioritizing water policy, and etc.
