해마다 여름철에 동해안 해수욕장을 찾는 피서객이 늘어남에 따라 그와 비례하여 해수욕장 안전사고도 늘고 있는 것이 현실이지만 해수욕장의 안전관리 실태나 피서객의 안전의식은 과거와 크게 달라진 것이 없으므로 안전사고도 늘어날 수밖에 없는 현실이다. 이에 해수욕장 안전사고를 줄이기 위한 첫 단계로 피서객들이 어느 정도의 안전의식을 가지고 있는가와 과연 그들이 자신들이 방문한 해수욕장의 안전시설이나 관리 상태에 어느 정도 관심을 가지고 있는지 그리고 만족하는지를 조사하여 보았고 구체적으로 어느 부분에 문제가 있는 지를 개별면접을 통한 설문조사를 광범위하게 실시하여 본 논문을 작성하였다. 설문 기간은 1999년 7월 29일부터 8월 9일까지 2주일 동안 동해안의 주요 해수욕장인 속초해수욕장, 낙산해수욕장, 경포대해수욕장, 망상해수욕장의 4곳의 해수욕장에서 600여 개의 설문지를 토대로 여러 가지 질문들에 대한 SAS 통계 분석을 시도하였다. 우리나라 실정에 맞는 해수욕장 안전관리 가이드 라인을 설정할 수 있는 기초 연구로 삼기 위해 이 조사를 수행하였다. 차후 연구는 이를 기초로 하여 보다 광범위한 설문조사 및 실태조사를 실시하고 분석하고, 다른 나라의 해수욕장 안전 관리 실태와 비교 분석하여 우리나라의 현 상황을 진단한 후, 우리나라 실정에 맞는 해수욕장 안전관리 가이드 라인을 설정할 수 있을 것이다.

Recently rip currents are frequently observed in the summer at the beaches located along the East Sea coast. To understand the generation types of rip currents occurred at the Ease Sea beaches, numerical simulations of rip currents over the topographies of the Sokcho, Naksan, Gyeongpo, Mangsang beaches were performed by using a Boussinesq-type wave and current model, FUNWAVE. The offshore and nearshore topographically-controlled rip currents and the transient rip currents were well reproduced due to the alongshore non-uniformities involving the phase interaction effects. This study looked over the generation types of rip currents to occur at the beaches with complicated field bathymetries.

This paper introduces X-band radar-based surface current measurement technique. A marine X-band radar used for navigation was installed at Sokcho Beach to collect surface current data in real time. Based on this, in order to verify the accuracy of the measurement of surface current (Current speed), the Korea Hydrographic and Oceanographic Agency Marine observation buoy compared it with the data. Data collected from January 2022 were compared and as a result the possibility of surface current(Current speed) measurement using radar confirmed.

본 연구에서는 컴퓨터 비전 기반의 딥러닝 객체 인식 기술을 이용하여 속초해수욕장에서 수집한 레이더 이미지에서 선박, 섬 및 부유체에 대해 탐지(Detection), 인식(Recognition)하는 연구를 수행하였다. 2021년 8월에 수집한 레이더 영상을 이용하여 본 연구를 수행하였으며, 움직이는 물표와 섬 등을 구분하였다. 일부 환경적인 제약에 따라 에러 발생이 있었지만, 향후 현재까지 수집한 레이더 영상을 추가하여 정확도를 높일 예정이다.

This paper analyzes wave measurement using X-band navigation (ship) radar, changes in radar signal due to snowfall and precipitation, and factors that obstruct wave measurement. Data obtained from the radar installed at Sokcho Beach were used, and data from the Korea Meteorological Administration and the Korea Hydrographic and Oceanographic Agency were used for the meteorological data needed for comparative verification. Data from the Korea Meteorological Administration are measured at Sokcho Meteorological Observatory, which is about 7km away from the radar, and data from the Korea Hydrographic and Oceanographic Agency are measured at a buoy about 3km away from the radar. To this point, changes in radar signals due to rainfall or snowfall have been transmitted empirically, and there is no case of an analysis comparing the results to actual weather data. Therefore, in this paper, precipitation, snowfall data, CCTV, and radar signals from the Korea Meteorological Administration were comprehensively analyzed in time series. As a result, it was confirmed that the wave height measured by the radar according to snowfall and rainfall was reduced compared to the actual wave height, and a decrease in the radar signal strength according to the distance was also confirmed. This paper is meaningful in that it comprehensively analyzes the decrease in the signal strength of radar according to snowfall and rainfall.

본 연구는 동해안 속초항에 정방형 직교격자체계(Regular Grid)와 직교-곡선 격자체계(Orthogonal Curvilinear Grid)를 이용하여 SWAN 모형에 적용시켜 각 격자체계에 따른 파랑변형의 특성을 비교하는데 목적이 있다. 본 연구결과 북방파제가 연장 중인 방파제 선단에서 회절현상이 관측 되었으며, 속초 해수욕장 인근에서의 해안선 형상에 따라 굴절 효과로 인하여 입사 파랑의 벡터들이 해안선에 수직하게 입사되는 현상이 관측 되었고, 특히, 조도 주변에서 파랑의 굴절 효과와 차단효과를 관찰할 수 있다. 정방형 직교 격자체계와 직교-곡선 격자체계의 계산결과는 유사하나 직교-곡선 격자체계가 해안선에서 보다 정밀한 계산 값을 얻을 수 있었다. 하지만 직교-곡선 격자체계는 계산시간이 최소 4배 이상 증가하는 단점을 가지고 있다.

This paper explains the comparison results of surface current measurement using X-band Radar image through analysis. Measurements were carried out from February 2022 using the X-band Radar for marin ships installed at Sokcho Beach. Based on the Korea Hydrographic and Oceanographic Agency ocean observation buoys, the accuracy of surface current(current speed) measurement was verified through comparison and analysis of measurement data.

The purpose of paper is to examine about Street Furniture in swimming beach. The beach space is the very important place not only to spend in season but also to use 4-seasons in leisure culture. To offer better landscape in spacial beach; Gyeongpo, Naksan, Mangsang, Samcheok and Sokcho, such as regional atmosphere and identification are to analyze with design criteria. For the amenity of users through the improvement of landscape may be possible to work out future of beach surroundings. Accordingly material, form and color can be estimated systematically. This research suggests that design of street furniture is to be environmental and regional control. As a result, some proposal of Street Furniture by analysis, designer and officer have to focus on establishing a comprehensive plan for the attractive beach space.

Mixing zone characteristics of the wastewater effluents discharged from Sokcho ocean outfall have been investigated using an outfall mixing zone model which was developed on the basis of Huang et al.'s(1996) analysis method. The model was applied to Sokcho ocean outfall case and was used to simulate the concentration distribution of wastewater effluents using winter season's data, ie. daily effluent flowrate, ocean current and density stratification data which were measure for two months in the outfall area. Hourly concentration distribution of outfall effluent discharges was calculated and they were averaged for the period of 15 days which covers the ambient flow variability of the neap and the spring tidal currents. The results show that near-field dilution was relatively high with the minimum dilution of 130 for the winter season. The mixing zone was extended to the coastal beach area rather than offshore because of major direction of coastal currents. This may cause a deteriorating impact on coastal water quality, especially to the adjacent swimming beach area.

In this study, the marine environment is measured and analyzed in real time through the X-band radar installed on the rooftop of the Sokcho Beach administrative Welfare Center and Ulleungdo. Afterwards, the goal is to transmit the analysis results to the client PC. Using electronic maps and electronic navigational charts, the measurement results are overlaid on GIS (spatial information system), real-time data are shared through a website, and information is displayed through a web server. Currently, CCTV information and marine environment information are displayed on the website, but various application studies such as the use of Open AP I will be conducted in the future.
