Grasp of the wave of behavior that run up the beach

INUKAI Naoyuki

Behavior of the waves off the coast is known many¡¥However, to prevent marine accidents is not enough by itself¡¥The purpose of this study understanding of the wave of up the land¡¥¡¡This research is done by using the wave-making waterway¡¥
Water accidents occurred in Jokehama coast¡¥5 people were killed by accident¡¥Accident happened by a large wave that suddenly occurred¡¥It was examined, such as water depth and waves of information at the time of an accident¡¥Determined for a wave to carry out reproduction from the results of examination¡¥
It was determined first scale before making an experimental device¡¥Scale became one twentieth¡¥I made a terrain model in this scale¡¥I made a model using the wood¡¥The experimental apparatus to put the model to the wave-making waterway¡¥And taking a video of the wave in the video camera¡¥To analyze the motion of the waves from the captured image¡¥And adjustment of the water level before conducting the experiment¡¥It was corrected by the tide level and wave-setup¡¥Were analyzed elements such as speed of the waves from the image¡¥When comparing the experimental and the actual phenomenon, The experimental value is smaller¡¥The cause was considered in the two-dimensional terrain¡¥Terrain of Jokehama is a three-dimensional, there is a beach cusp¡¥Therefore, the experimental value was smaller¡¥ It was possible to know about the maximum height and the maximum flow speed of the wave¡¥Children in a small wave of Significant wave is necessary to be careful because there is a risk of being washed away¡
