Songjung beach located in Busan has been developed without design concept or any specific plans for its characteristics. This study attempts to suggest design ideas with specific plans and 3D perspectives in order to develop Songjung beach based on the characteristics and needs of the visitors and provide its own identity. The research was performed in three steps: First, the researcher visited the beach and explored how the beach facilities were used. Second, the satisfaction level and needs on the beach were investigated by questionnaire. Third, the specific plans were suggested based on the above results, which included 5 poly units with restroom, shower room, snack bar, fast-food restaurant, internet Cafe and cafeteria, etc. The form and color of the poly units were decided to show Korean traditional roof image and provide unique image to Songjung beach. This study will show a good example of beach design project reflecting visitors' specific needs through the research.

This research was conducted to evaluate tile effects of polluted Suyeong River water on the water quality of Kwangan-Ri bathing beach. The quantity of pollutant loading of Suyeong River was determined in January 1979, and the directions of tidal currents and the chemical constituents of the Suyeong Bay water were observed in May 1979. The results are as follows: The quantity of total pollutant loading which was discharged into Suyeong Bay is: BOD 75.2ton/day; COD 96.9ton/day; SS 20.5ton/day; ammonia-nitrogen 12.4ton/day; nitrate-nitrogen 430kg/day; nitrite-nitrogen 85.1kg/day; phosphate-phosphorus 594kg/day and total heavy metals 3.01ton/day. Considering the tidal current, the polluted waters of Suyeong River flow off the Kwangan-Ri beach during tile ebb tides, and flow into the Kwangan Ri beach during the flood tides. Consequently, the water quality of Kangan-Ri bathing beach is not suitable for bathing.

In the present study, a beach survey such as sand sizes, swim zone widths, and slopes of swash zone has been accomplished for 39 beaches along the Gangwon coastline. The data analysis presents that the swim zone width has a strong correlation with the sand size, showing that the swim zone width is reversely proportional to the 1.1 power of a grain size. The profile factor A has been analyzed using the beach profile form of $h=Ay^{2/3}$, where A was resulted to be proportional to the 0.77 power of a gram size.

The Gwangalli Beach, one of beaches representative of Busan together with the Haeundae Beach, is a tourist attraction, having increased tourists since the completion of Gwangandaero Bridge in 2003 and recording more than 10 million tourists in 2006. Although the competent local government office has conducted artificial beach nourishment/gravel removal projects every year to manage it, systematic monitoring and studies of erosion are insufficient. This study analyzed the changes in the coastline of Gwangalli Beach using aerial photos, tidal data, GPS survey data for the last sixty years, and examined how the Gwangandaero Bridge, which had been constructed on the Gwanganlli sea, has affected the changes. The results show that the area of Gwangalli Beach has increased 40% for the last sixty years, and that the effects of Gwangandaero Bridge on the coastline are insignificant.

본 연구는 해변의 양측에서 퇴적되고 해변 중앙에서 침식이 일어나고 있는 광안리 해수욕장에 최소 해빈폭을 최대로 하는 최적의 양빈 설계를 하고자 실시하였다. 광안리 해수욕장에 3가지 case의 양빈안을 수치 모의 시나리오로 구성하여 OneLine Shoreline Model을 적용하여 해빈폭의 시간적 변화를 모의하였으며, Cross-shore Profile Model을 적용하여 연평균 파고에 따른 전진폭과 최고 파고에 따른 침식폭을 추정하였다.

본 연구에서는 해안침식이 진행되고 있는 해운대 해수욕장의 장기 해안지형 변화 및 인근지역의 토지피복 변화에 대해 분석하였다. 지난 60여 년간의 항공사진을 이용하여 해안선을 추출하고 이를 수심측량 및 GPS측량 자료를 이용하여 조위보정한 후, 해빈면적을 추출하여 해안지형 변화를 분석하였다. 또한 환경부 토지피복 세분류를 기준으로 하여 육안판독을 통해 13개년도의 토지피복도를 제작하고 토양유실량을 산정하여 연도별 토지피복 변화를 분석하였다. 그 결과, 해운대 해수욕장의 해안선이 점진적으로 후퇴하고 있으며 해수욕장 면적이 전체적으로 감소하고 있는 것으로 나타났다. 춘천천 복개 및 도시개발에 의한 모래 공급원 차단이 이러한 해안침식에 영향을 주는 인위적 원인이라고 사료된다.

본 연구에서는 용기포항 동방파제 건설이 사곶 수욕장에 미치는 영향을 평판재하시험, 토질분석시험, 위성사진 자료 분석, 파랑, 조류, 수심 등의 현장관측과 파랑, 파랑류, 조류, 그리고 퇴적물 이동 등에 대한 수치모형을 통하여 사곶해수욕장의 동역학적 특성을 파악하였다. 평판재하시험과 토질분석시험 결과 기존의 사곶해수욕장 지역의 지지력 변화는 거의 없는 것으로 나타났으며, 방파제 건설로 인해 퇴적이 진행 중인 지역은 상대적으로 지지력이 낮게 나타났다. 현장관측으로 수집된 파랑, 조류, 수심의 자료는 수치모형의 입력 값으로 사용되었으며, 파랑류 수치모형결과 사곶 해수욕장 부근에서 파향에 따라 약한 소규모 와류가 발생하였으며, 퇴적물이동 수치모형의 경우 국소 와류에 의한 지형변화가 발생하였으며, 남서와 북동에 약간의 퇴적이 발생하였다.

Bathing beach may be one of the ocean resorts in popular, which peoples can easily access in summer. Three beaches in Jeiu island are surveyed about natural environmental conditions using coastal engineering technique and questionnaire are carried out. Also the satisfaction index on the sand size, wave height, water temperature, transparency and bottom slope is gained very well. The results obtained from this study can be utilized making a new artificial bathing beach in the future.

$100\%$천연향을 이용하여 제작, 개발된 해충기피제의 기피력을 테스트하였다. 해충기피제를 착용한 그룹과 착용하지 않은 그룹으로 구분하여 실험실에서 사육한 모기와 서해안에 위치한 몽산포 해수욕장, 동해안에 위치한 낙산 및 선악 해수욕장과 천안에 있는 태조산에서 해충에 대한 기피력을 측정하였으며, 각 그룹별로 5명씩 5회에 걸쳐 각 회당 1시간동안에 흡혈개체로부터 물린 갯수를 확인하여 이들의 평균값을 계산하였다. 그 결과, 실험실에서는 $91\%$, 몽산포 해수욕장에서는 $78\%$, 낙산 및 설악 해수욕장에서는 $93\%$, 태조산에서는 $90\%$의 기피력을 보여주었으며, 이는 상당히 탁월한 기피 효과를 나타내었다.
