碩士 / 國立臺灣海洋大學 / 海洋環境資訊學系 / 95 / In recent years, coastal recreational activities, such as fishing and diving, are increasingly popular in the northeastern coast. Accompanying with these activities is a heightened chance of incidents of people in distress in the water, which requires coastal guard units for search and rescue. Better knowledge in how the people drift in this area is essential in the success of finding them promply.
The present study used a manikin type float to simulate drift of people in water. The float was equipped with a GPS device for recording the positions of the float. Six drift experiments were carried out. The trajectories were compared to that calculated using calculated tidal current vector and wind drift current and leeway vectors based on the method provided by the US coast guard.
The results showed that the calculated direction of the drift trajectories generally match the observed ones, with some cases having good agreement. This study shows that the calculation method used herein can be used in this area.
