Many reclaimed tideland projects in Korea have been conducted to secure the food self-sufficiency. In fact, the domestic food self-sufficiency has been greatly improved and reclaimed tideland projects contribute to Korea's economic and social development directly or indirectly replacing agricultural lands from urbanization, industrialization. As result, current self-sufficiency of rice reach the demand(104.6%) while rate of upland crops has less than 30% of self-sufficiency rate and corn, wheat, soybeans, etc. are virtually dependent on imports. Domestic price of crop is expected to be unstable by trend of international grain prices. Therefore, developing reclaimed tidelands as upland which is originally constructed for paddy fields could be a good option to become steady in domestic crop market and dedicate to ensure a stable food security. The study to prepare measures for dealing with disasters in reclaimed tidelands of west coast district is required in order to utilize those sites for infra construction of multi-utilization in those sites and The result of flooding analysis in this study can suggest policy direction for practical utilization of reclaimed tidelands in yellow sea area.

Korea is surrounded by the West Sea, the South Sea, and the East Sea. There are various points at which large and small rivers flow into the sea, and areas where these rivers meet the coast are vulnerable to disasters. Thus, it is necessary to study disaster prevention techniques based on coastal characteristics and the pattern of disasters. In this study, we analyzed the risk factors of disaster districts analyzed in comprehensive plans for the reduction of damage to coastal cities from storms and floods. As a result of standardization, four factors (tide level, intensive rainfall & typhoon, wave, and tsunami) were identified. Intensive rainfall & typhoon occurred along the West Sea, the South Sea, and the East Sea coast. Factors that should be considered to influence disasters are tide level for the West Sea, tsunami and tide level for the South Sea, and wave in the East Sea. In addition, disaster prevention techniques to address these factors are presented, focusing on domestic and overseas cases.

지난 20년간(1998-2017년) 한국해양학회지(바다)와 한국수산과학회지에 실린 한글 논문 중 우리나라 주변 바다 이름을 지도에 표기한 논문들을 대상으로 그 표기 방법을 살펴보았다. 지도에 표기된 바다 명칭들의 형태는 크게 세 가지 - 'East Sea(동해)와 Yellow Sea(황해)', 'East Sea(동해), Yellow Sea(황해), South Sea(남해)', 'East Sea(동해), West Sea(서해), South Sea(남해)' - 가 있다. 'East Sea'는 모든 논문에서 'East Sea'로 표기된 반면, 'Yellow Sea'는 'West Sea'와 혼용해서 사용되고 있었다. 'Korea Strait(대한해협)' 대신 'South Sea'의 사용 빈도도 높았다. 이 결과는 연구자들이 해안선으로부터 가까운 연안해역을 우리나라를 기준으로 지리적 방위에 근간하여 부를 때 사용하는 바다 명칭과 주변해에 대한 국제적인 바다 명칭을 혼용하여 사용하고 있음을 보여 준다. 따라서 우리나라 해양 수산 연구자들이 바다 이름표기에 관한 기준을 세우고 일관성 있게 표기하는 것이 시급하다. 이와 관련하여 이 연구에서는 연구논문 작성 시에 주변해와 우리나라 연안해역에 대한 바다 명칭을 서로 구분하여 사용할 것을 제안하였다. 즉, 주변해는 국제적으로 통용되고 있는 'East Sea(동해)', 'Yellow Sea(황해)', 'Korea Strait(대한해협)', 'East China Sea(동중국해)'로 사용하고, 이들 주변 바다에 포함되어 있는 연안해역은 우리나라를 기준으로 상대적 방위에 근거한 'Coastal Sea off the East Coast of Korea(한국 동쪽 연안 바다)', 'Coastal Sea off the West Coast of Korea(한국 서쪽 연안 바다)', 'Coastal Sea off the South Coast of Korea(한국 남쪽 연안 바다)' 등으로 표현할 수 있다. 다른 표현으로는 'East Korea Coastal Zone', 'South Coastal Zone of Korea', 'West Korea Coastal Zone'으로도 표현할 수 있다. 작은 규모의 특정 해역의 경우 해양지명(해상지명과 해저지명)을 사용하여 연구해역을 표기할 수 있다.

This study is to enhance the provincial leisure plans through various programs and infrastructure facilities and to establish a network of natural leisure areas in Gyeonggi-do. According to the result, first, in terms of analyzing the locations of natural leisure areas by types, the rest of urban parks is formed in the Capital area outside Seoul as centering around the central area. Moreover, with regard to the rest of forest and the rest of natural ecology learning, the area of the detention exceeds the total area of Gyeonggi-do. The rest of valleys and swamps showed a dotted pattern of the detention area while the rest of tideland and fishing village experience indicated a distribution of the detention area along the West Coast as an axis. Second, according to result of analyzing the accessibility of natural leisure areas by types, the rest of valleys and swamps showed the highest accessibility among the natural leisure areas : the rest of natural ecology learning had the medium level of accessibility; the rest of forest indicated the lowest accessibility. Therefore, it is necessary to create more leisure areas concerning the futures demands. In addition, they should be constructed in the places adjacent to the urban district area exhibiting higher usability and accessibility. In the places where there are many natural leisure area with higher utility, management plans should be deliberated as well. Based on the result of analyzing the rest of valleys and swamps and the rest of tideland and fishing village experience, it was found that the natural leisure area should improve the quality of water intensively and hydrophile property and create hydrophilic spaces. The development of natural leisure areas need to be carried out under the principle of environmental protection while considering historic sites and nearby rivers and lakes. Moreover, water leisure programs should be developed actively as well with further utilization of water resources in order to enhance the usability of natural leisure.

New Zealand suffers from regular floods, these being the most common source of insurance claims for damage from natural hazard events in the country. This paper describes the origin and distribution of the largest floods in New Zealand, and describes the systems used to monitor and predict floods. In New Zealand, broad-scale heavy rainfall (and flooding), is the result of warm moist air flowing out from the tropics into the mid-latitudes. There is no monsoon in New Zealand. The terrain has a substantial influence on the distribution of rainfall, with the largest annual totals occurring near the South Island's Southern Alps, the highest mountains in the country. The orographic effect here is extreme, with 3km of elevation gained over a 20km distance from the coast. Across New Zealand, short duration high intensity rainfall from thunderstorms also causes flooding in urban areas and small catchments. Forecasts of severe weather are provided by the New Zealand MetService, a Government owned company. MetService uses global weather models and a number of limited-area weather models to provide warnings and data streams of predicted rainfall to local Councils. Flood monitoring, prediction and warning are carried out by 16 local Councils. All Councils collect their own rainfall and river flow data, and a variety of prediction methods are utilized. These range from experienced staff making intuitive decisions based on previous effects of heavy rain, to hydrological models linked to outputs from MetService weather prediction models. No operational hydrological models are linked to weather radar in New Zealand. Councils provide warnings to Civil Defence Emergency Management, and also directly to farmers and other occupiers of flood prone areas. Warnings are distributed by email, text message and automated voice systems. A nation-wide hydrological model is also operated by NIWA, a Government-owned research institute. It is linked to a single high resolution weather model which runs on a super computer. The NIWA model does not provide public forecasts. The rivers with the greatest flood flows are shown, and these are ranked in terms of peak specific discharge. It can be seen that of the largest floods occur on the West Coast of the South Island, and the greatest flows per unit area are also found in this location.
