To clarify the effects of wind and wave run-up on the transportation of the splash caused by wave overtopping, field observations were conducted at Waku fishing port in Yamaguchi prefecture in the winter season over two years from December 2005 to February 2007. The violent wave run-up at a vertical breakwater and the transportation of splash by wind were recorded with 3 digital video cameras. Besides, incoming waves were measured with a wave gauge and wind was also measured with a wind anemometer. On the basis of observation data, several findings were obtained: 1) there are high correlations among the wave heights, wave run-up heights and the distance of splash transportation, 2) contrary to expectation, relatively low correlations are found between the distance of splash transportation and wind velocity, 3) the distance of splash transportation can be estimated from the wave run-up height and wind velocity with a simple expression obtained by multiple regression analysis.
