오목한 호수 지형과 강한 비선형 내부파간의 상호작용 3차원 모델링 및 호수 괴물 현상

Abstract

In the present study degeneration of the strongly nonlinear internal seiches in elongated lakes with a concave spoon-like topography is investigated. Two different three-dimensional non-hydrostatic free surface numerical models are used to investigate degeneration of internal waves and its subsequent interactions with the concave lake slope.The appearance of surface wake in such idealized elongated elliptic-shape lake was the motivation for carrying further modeling of the internal seiches in the real lake. This penomenon can be the explantion of the fact that number of eyewitness around the world claimed to see lake monstres moved rapidly and the submerged leaving a wake.ed to investigate degeneration of internal waves and its subsequent interactions with the concave lake slope.The appearance of surface wake in such idealized elongated elliptic-shape lake was the motivation for carrying further modeling of the internal seiches in the real lake.
