This paper evaluated types and characteristics of development projects occurred in coastal area (Public Water) by analyzing an application status of Sea Area Utilization Conference System that effective protect and manage marine environment and ecosystem from various artificial utilization and development enforced in 2008. Also, system improvement for stable settlement and security of efficiency considering exposed problems during system enforcement were diagnosed. The number of Sea Area Utilization Conference (SAUC) performanced during the period of 2009-2010 was 3,705, which consisted of simple SAUC (87.0%), general SAUC (12.8%), and Sea Area Utilization Impact Assessment (SAUIC; 0.2%). The general SAUC was accomplished for Public Water reclamation (43.4%), seawater supply and drainage (17.5%), dredging sediment (5.5%), installation of port facilities (4.6%) and fishing harbor facilities (2.3%), and others (23.4%). Statements of Environmental Impact Assessment (EIA) were reviewed mainly for construction of port facilities (32.9%), followed by construction of industrial complex, development of tourism and leisure complex, road construction, and development of energy facilities. It would be necessary to strengthen effectiveness of the system, advertisement, and capability of conference and review agency, and to enhance confidence of marine EIA continuously, according to the increase of development projects, and diversity and enlargement of development types.

The south-western part of Korea is situated in an unbalance of water supply and demand relating to the Keum, Mankyung, Dongjin and Youngsan River and their estuary reservoirs. For example, the Keum River estuary reservoir is discharging the larger amount of yearly runoff into the sea due to the small storage capacity, while Saemankeum estuary reservoir which is under construction, has the smaller runoff amount comparing with its storage capacity, And the downstream area of the Youngsan River, such as Youngkwang, Youngam are deficient in water due in larger demand and smaller supply. In order to solve the above unbalanced water supply and demand and also to improve the water use efficiency, the Hierarchical Operation Model for Multi-reservoir System(HOMMS) has been developed and applied to analyze the multi-reservoir operation assuming that the above reservoirs were linked each other. The result of this study shows that 2,148MCM of annual additional water requirement for agricultural and rural water demands are required in this region at 2011 of target year, and these demands can be resolved by diverting and reusing 1,913MCM of the released water from the estuary reservoirs into the sea.
