The conventional water budget analysis methods for major water works do not take the spatial variation of available water resources into account. There has also been a tendency of over-estimation of water supply capacity when a significant inter-basin water transfer is involved. Therefore, a revised water budget analysis methodology is proposed which can take care of the spatial variation of the water resources available within the basin and with the inter-basin transferable water. For the purpose of present study, the Saemangeum project area is taken for the analysis, which includes both the Dongjin and the Mangyungs River basin, one of the regions with the most complex water utilization.

풍력발전시스템은 제품에 대한 실증이 반드시 현장에서 이루어져야 하는 특성을 가지고 있으며 향후 국내실정에 적합한 풍력발전시스템의 개발과 보급을 위해서도 실증연구는 선행조건으로 볼 수 있다. 따라서 국제 규격에 합당한 풍력발전 성능평가와 현장 실증연구를 수행할 수 있는 실증단지를 국내에 조성하는 것이 매우 시급한 실정으로, 기초적인 자원분석과 주변환경평가 등을 거치면서 기본적인 실증단지 후보지들을 비교하여 최종 후보지로 선정된 전북 새만금지역, 병곡 영해 평야지구, 제주 동부해안지역 월정지구, 서부 해안지역 월령지구에 대하여 부지의 IEC 규격 적합성 검토, 인프라구축에 대한 적정성 검토, 주변 발전단지 조성가능성 및 발전사업에 대한 연계성 검토, 육해상 실증단지 구축 동일지 역 가능성 검토, 교육과 홍보에 대한 접근성 및 공사에 대한 접근성 검토, 부지 확장 및 향후 실증단지 운영과 관련하여 지자체와의 연계성 검토를 하였다.

The purpose of this study was to investigate the changes of the sea bottom topology during construction of Saemangeum seadikes. Sea water depth and bottom topology in the Saemangeum area were measured every year and the surveyed data under construction of Saemangeum seadikes were analyzed and compared to the initial conditions before construction, There was erosion in the overall surveyed areas and the depth of erosion was approximately 53cm compared to the data in 1988. The center sandbanks of Seadike 2 did not show the great changes due to two main channels those were developed in northeast and southeast. The inland sandbanks of Seadike 4 showed the development of great erosion and deposition partially because of the changes in tide direction which developed as a result of the completion of Seadike 3 and the completion of a seadike of the Kunsan-Changhang industrial park at the north of Saemangeumm area.

A 33-km long sea dyke is being constructed in the Saemangeum area mid-west of Korea to reclaim a surface area of 40,100 ha which includes well-developed tidal flat and two river estuaries. The northern part of the dyke was closed on 10 June 2003, while the southern part was recently closed on 21 April 2006 by plugging two opening gaps of 2.7 km in length. In this study, firstly we review the outlines of key national projects which described marine environments in the Saemangeum area and secondly we present a summary of remarkable changes in marine environments after the closure of the northern dyke, based on marine environmental data collected during 2002-2005. Details in each discipline of the marine environments are presented both in other papers of this special volume and in a series of annual reports of the Ministry of Maritime Affairs and fisheries.

유역단위에서 수문모델링을 수행함에 있어 토양수분은 물수지 관점에서 매우 중요한 인자로 고려된다. 더욱이, 최근 발생빈도가 커지고 있는 가뭄을 효과적으로 평가하고 예측하는 데에도 활용성이 매우 큰 것으로 인식되고 있다. 이러한 중요성에도 불구하고, 가용자료의 부족, 자료의 부정확성 등으로 인해 실제 유역모델링을 수행하는데 있어 활용도는 매우 적다. 이러한 점에서 본 연구에서는 동질성이 확보된 유역단위를 기준으로 다지점의 토양수분 자료를 추계학적으로 모의할 수 있는 기법을 개발하고자 한다. 토양함수자료는 지속성(persistence)이 매우 큰 특징을 가진다. 즉, 상태의 지속성이 크며 메모리가 오랫동안 유지된다는 점에서 추계학적 모의가 가능할 것으로 판단된다. 이러한 지속성을 이용함과 동시에 토양함수를 다양한 상태로 분리하고 이들 상태들간의 천이확률을 효과적으로 모의할 수 있다면 관측 토양함수 자료의 통계적 특성 재현이 가능하다. 본 연구에서는 용담댐 유역에 대해서 개발된 모형을 적용하고 활용성을 검토하고자 한다.

Raclamaton of tidal flats has been practiced in Korea since the fifteenth century mainly for agiculatural porposes. The total area of reclaimed lands in 1994was estimated to be 400 k$m^2$ which corresponds to 2% of the national farm land. Recently, reclamation has been undertaken extensively, and such a huge projects as Samemankum Development will add over 401k$m^2$ by 2004. The impact of coastal reclamation on the environment is enormous. Most of them are presumably instrumental in causing local changes of coastal ecology. Reclamation is expected to be undertaken continuosly and adverse effects are expected. The authors ineended to identify the impacts of reclamation on the study area, to seek the causes of the environmental prolems of Shiwha-District Reclamation, and to analyze ite Environmental Impact Assessment to for environmentally sound sustained development.

Solar power has the largest proportion of power generation and facility capacity among renewable energy in South Korea. Floating solar power plant is a new way to resolve weakness of land solar power plant. This study analyzes the power generation of the 18.7 MW floating solar power project located in Saemangeum, Gunsan-si. Since the solar power generation has a characteristic that is greatly affected by the climate, various methods have been applied to predict solar power generation. In general, variables necessary for predicting power generation are solar insolation on inclined surfaces, solar generation efficiency, and panel installation area. This study analyzed solar power generation using the monthly solar insolation data from the KMA (Korea Meteorological Administration) over the past 10 years. Monte Carlo simulation (MCS) was applied to predict the solar power generation with the variables including solar panel efficiency and insolation. In the case of Saemangeum solar power project, the most solar power generation was in May, the least was in December, the average solar power generation simulated on MCS is 2.1 GWh per month, the minimum monthly power generation is 0.3 GWh, and the maximum is 5.0 GWh.

전통적으로 우리나라의 농업용수 공급시스템은 개수로 방식이 주로 사용되어 왔으나, 최근에는 지형의 영향을 덜 받으면서 안정적으로 용수공급이 가능한 관수로 시스템으로서의 전환이 늘어나는 추세이다. 특히 서남해안간척사업, 새만금 등 대단위 농업단지 조성이 늘어나면서 경제적인 수리시설의 설치와 유지관리에 대한 관심이 증대되고 있다. 우리나라의 관수로화 사업은 1980년대 중반부터 농업용 관수로 사업이 시행되어 왔다. 그러나 현재 운영 중인 농업용관수로 지구에서는 특별한 물관리에 대한 규정이 없고, 사용자의 급수요청에 따른 불규칙한 용수관리운영이 이루어지고 있다. 또한, 농업용수의 무분별한 사용과 운영관리방안의 부재로 인해 많은 양의 농업용수가 낭비되고 있다. 기존 개거에 비하여 관수로의 경우 통수량이 증가되어 관개에 소요되는 시간은 단축 되었으나, 급수소요시간의 변화에 따른 적절한 적용을 하지 못하여 지나치게 많은 양이 공급되고 있다. 이러한 문제점으로 인하여 발생되는 수자원의 낭비를 막기 위해 농업용 관수로의 운영계획이 필요하지만, 현재 농업용 관수로 운영기준은 사실상 없는 실정이다. 본 연구에서는 현재 운영되고 있는 호남지역의 해남지구를 대상지구로 선정하여 EPANET(US Environmental Protection Agency)모형을 이용하여 농업용 관수로시스템의 관망해석을 실시하고자 한다. EPANET모형을 통하여 대상지구의 급수방식을 분석하고, 용수량의 운영현황 자료를 비교 검토하여 계획수요량과 공급량을 비교하여 관수로시스템에서의 농업용수 공급능력을 검토하고자 한다.

Reclamation is the act of creating new lands by constructing dikes in offshore tidal flats to utilize them for various purposes, including the establishment of farmland to secure food for an increasing population. Based on the fact that reclamation has resulted in drastic changes in the environmental, economic, social, and cultural aspects of land expansion and development, population movement, and the formation of cities since ancient times, I reviewed the value of reclamation sites and addressed the issue of how to preserve and utilize them. "Reclamation culture" refers collectively to the recognition and concept system, behavior styles, and cultural products created by changes in the environment, and the tangible, intangible, and natural heritage generated directly and indirectly by reclamation is defined as "reclamation cultural heritage". It shows that the historical background of reclamation accords with prevailing trends, and that the reclamation sites possess cultural heritage value due to their historical, academic, and scarce characteristics. Numerous reclamation cultural heritage sites at the Gwangwhal and Gyehwa dikes are on the verge of being destroyed, with their original function having ended after the construction of Saemangeum Sea Wall. I propose measures to preserve these under the principle that utilization is based on the basic premise of conservation. First of all, modern and contemporary reclamation sites must necessarily be designated and managed as registered cultural properties, local cultural heritage, future heritage, and agricultural heritage. In particular, as it has been confirmed that reclamation sites created after the Goryeo and Joseon dynasties and the 1950s have not been designated as cultural heritage sites. It is necessary to review the characteristics and values of such reclamation sites through a full survey of national reclamation data. Effective and sustainable utilization of reclamation cultural heritage, which has not been acknowledged in the past due to its close relationship with our lives, is necessary to search for hidden stories found within that heritage, to organize governance for the efficient use of reclamation resources, and to build a museum to collect and display the history and culture of the reclaimed areas. Finally, through links with countries with experience in reclamation, we will be able to cope jointly with international issues such as those pertaining to society, culture, and environment, and would be able to implement various projects to further the advancement of human beings.
