초록

한국 남서해 다도해역 주변의 조석 조류특성을 파악하기 위해 2차원 수치모델을 이용하여 다도협수로역, 섬과 육지사이 수로역, 섬 주변 개방해역 주변 4개 해역의 조석 조류 계산 결과를 비교하였다. 조류 최대유속은 다도협수로역에서 31.92 cm/s로 작았고, 섬주변 개방역에서 87.55 cm로 컸다. 조석잔차류는 협수로가 길고 수로 내 섬이 많은 해역에서 컸다. 조석에너지 분산과 조석진폭의 변동범위는 다도협수로역($392.6{\times}10^7$ erg/s, 99.0 cm)이 가장 크고 섬과 육지사이 수로역($125.7{\times}10^7$ erg/s, 11.6 cm), 섬 주변 개방역($23.1{\times}10^7$ erg/s, 8.1 cm) 순서로 작았다. 즉 다도해역 내 협수로와 수심의 급격한 변화가 조석에너지 분산에 큰 역할을 하고 있는 것으로 나타났다.

In order to estimate the tide and flow properties around the archipelago, around Dolsan, Choyak, Geogeom and Jindo which located in the southwestern waters of the south sea of Korea, tidal currents, residual flows and tidal energy dissipation were investigated by using 2-dimensional numerical model. The maximum speeds of tidal currents are small around Dolsando(31.92 cm/s) and large around Jindo(87.55 cm/s). The residual flow is fastest around Choyakdo where many channels and islands as compared with other study areas. The area around Jindo has the highest currents speed, but shows the flat movements. The margins between the maximum and the minimum dispersion rates of tidal energy in the areas are estimated and designate the order of values around Dolsando($392.6{\times}10^7$ erg/s), Geogeumdo($125.7{\times}10^7$ erg/s) and Jindo($23.1{\times}10^7$ erg/s) sequently. These circumstances are same as in the amplitude of M2 constituent. This means that rapid depth changes and narrow channels play an important role in tide and tidal currents energy in archipelago.
