서울 토박이로서, 부산 해운대는 이따금 TV에서나 보았던 한여름의 뜨거운 햇살과 수많은 인파로 북적이는 백사장으로 기억된다. 그러나 부산 해운대의 촬영장을 찾은 날은 내 기억과는 정반대였다. 초겨울임을 알리는 차가운 바닷바람을 맞으며 '부산은 따뜻하겠지'라는 안일한 생각으로 얇은 재킷만 챙겨 부산 출장을 떠난 내 자신이 야속할 따름이었다. 본격적인 겨울의 시작을 알리는 12월. 우리 주변의 불우이웃을 돌아보고 함께 더불어 잘사는 세상을 만들기 위한 작은 첫걸음을 내딛는 12월 2일은 그렇게 시작하였다.

In this study, we analyzed the erosion variation of beach area at Haeundae Beach after coastal improvement project using video monitoring system operated by the Coastal Erosion Monitoring (Ministry of Oceans and Fisheries). Haeundae Beach was well maintained and stabilized following large scale nourishment through coastal improvement project despite of seasonal fluctuations. However, multiple typhoons over the last two years caused beach stabilization patterns and seasonal fluctuations to lost equilibrium, resulting in rapid erosion. In particular, the sandy beach was eroded by typhoon Solic and Kongray in 2018 and failed to recover beach area in winter by seasonal fluctuations. And due to multiple typhoons in 2019, the beach area was reduced 9.5 % (12,607 ㎡) year-on-year. According to analyze the observed wave and beach area data in Haeundae, the tendency of erosion and sedimentation was influenced by seasonal incident wave direction for each section(west, center and east part). Therefore, to identify the causes of decreasing seasonal fluctuation characteristics and continuous erosion, hereafter, more precise monitoring of different factors are needed, such as the crest heights of submerged breakwater and its loss of function, and sand leakage to the outside around submerged breakwater.

1970년부터 해운대 신시가지 조성 및 춘천의 복개공사, 해안 주변의 매립, 도로건설 등의 연안 관련 사업이 환경에 미치는 종합적인 영향에 대한 검토도 없이 시행되어, 해운대 백사장으로 유입되어야 할 토사가 주공급원인 육지로부터 잠정적으로 차단되었다. 해운대 해수욕장의 해빈이 갈수록 감소되고 있는 가운데, 유실된 토사가 퇴적되는 연안의 해저지형에 대한 조사를 통해 정량적인 분석과 기간별 침퇴적 경향을 알아보는 연구가 필요하다. 따라서 본 연구에서는 수심 측량 자료를 이용하여 GIS기법으로 해저지형도를 제작하였고, 해저지형을 등간격으로 나누어 각 구간별 침퇴적 경향을 분석해 보았다. 그 결과 계절별로 침퇴적을 반복하고 있었고, 여름에는 침식, 겨울은 퇴적되는 경향을 보였다.

Keratinophilic fungus (KPF), a type of dermatophytes, is usually present as normal flora on the skin of humans and animals but can produce ring worm-like dermatophytosis by invading the skin in infected individuals. They are distributed worldwide, but their occurrences vary distinctively in accordance with the geographical location and environmental change. Because these fungi grow by degrading keratin, they are abundantly found on the skin, hair, and nails, which are rich in keratin. To investigate the presence of keratinophilic fungi in the soil, we selected a popular beach in South Korea, Haeundae Beach, where numerous people gather each year during the summer holidays. Hundred soil samples were analyzed using the hair-baiting technique, among which, a total of 23 colonies of KPF were identified from 21 soil samples. The identified KPF were Microsporum gypseum (43%), Chrysosporium spp. (35%), Trichophyton ajelloi (13%), and Microsporum cookie (9%). This study confirmed that pathogenic fungi can be found in places crowded by many people. Further research and continuous data collection are needed to confirm the distribution of pathogenic KPF.

우리나라 대표적인 해운대 해수욕장은 백사장의 길이가 현재 약 1,400m, 폭은 $35{\sim}45m$, 평균수심은 약 1m에 달하는 대규모 해수욕장이다. 그리고 수심이 낮고 조차가 적으며, 수온이 따뜻하여 천혜의 조건을 갖춘 한국 최대의 해수욕장으로 한해 약 1200만 명이 넘는 관광객이 찾는 대표적인 명소이기도 하다. 그러나 지난 수십 년간의 해빈 유실로 인한 해수욕장의 존립자체의 위기가 현실화되고 있다. 해수욕장의 모래유실은 다년간에 걸쳐 진행되고 있으며, 여러 요인에 의하여 해안선의 위치와 폭이 달라지고 있다. 본 논문에서는 부산지역의 해운대 해수욕장을 선정하여 실험지역에 대한 측량을 RTK 방식으로 4개월간 3회에 걸쳐 실시하였다. 측량결과 1, 2, 3차에 걸쳐 총 3.36m의 해안선 증가의 효과가 나타남을 알 수 있었다. 또한, 모래포집시설을 설치하기 전, 후를 기점으로 비교한 결과를 파악하였으며, 향후 해빈 유실의 원인과 방지대책, 그리고 해안선 추출의 모니터링 시스템에 대하여 모색하고자 한다.

The width of Haeundae beach has been decreasing annually due to the loss of sand from land, high waves, reflected waves, etc.. The accurate prediction of wave-induced currents is indispensible to analyze the beach deformation due to the sediment transport. In the this study, Numerical experiments were performed with seasonal representative wave on the basis of a long term and comprehensive survey data. In summer, we found the deposition of Mipo by longshore current eastly by ordinary and S waves, and in winter, the deposition of Dongback-island by longshore current westly by ordinary and E waves. In addition, rip current occurs in the middle of Haeundae beach by 50 year return period wave and current westly along the coast by ESE directional wave.

We observed tidal currents throughout all four seasons in 2007 at a single station, located 1.6km off Haeundae Beach and compared these current data with wind data. The direction of seasonal wind represented a similarity between the winds at sea and on land but the speed of wind at sea was almost three times stronger than the wind on land. In addition, the wind at sea turned out to considerably affect on tidal currents, particularly from late summer to autumn. On the other hand, the thickness of Ekman Layer, indicating a limitation of wind influence, was estimated to be 31.8 m on average, suggesting that the entire water column is under the influence of wind. Therefore, we are required to consider the wind stress into the analysis of tidal currents for the prevention of the loss of sand from Haeundae Beach.

The shoreline changes were observed and analysed using the video image by a remote unmanned automatic camera monitoring system installed at Haeundae beach of Busan City. In order to analyse quantitatively the shoreline changes caused by waves and tides, the image averaging technique and the rectification technique for obliquely acquired image were applied to the video image during the typhoon Bart in September, 1999. The results showed that the camera monitoring system can be used as a very cost effective and efficient tool for monitoring shorelines which change continuously due to waves and tides.
