Abstract

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.

39개 동해 해수욕장에 대한 대표 입경과 유영폭, 포말대 경사 등을 조사하였다. 이 자료를 근거로 입경과 포말대 경사의 상관 관계를 살폈으며 해수욕장의 유영폭을 추정하는 데 있어 어떤 인자의 영향력이 더 큰가를 분석하였다. 분석 결과 대상 해수욕장에서는 유영폭과 대표입경의 상관성이 더 우월하며 유영폭이 대표입경의 1.15승에 반비례하는 결과를 얻을 수 있었다. 분석하는 데 있어 해빈 종단면 $h=Ay^{2/3}$ 식이 사용되었으며 해빈 종단면 축척 계수 A는 대표입경의 0.77승에 비례하는 것으로 분석되었다.
