Abstract
This study examined the application capability of high-order nonlinear Boussinesq wave model (BWM) which can calculate wave run-up for wave transformations in field shallow sea areas such as reef. In a simple example for uniform slope beach, it was found that BWM's outputs of irregular wave runups agreed well with the estimations by an existing runup formula. In cases of field coastal area of reef topography, the outputs by BWM were also good in agreement with observations and predicted wave heights by a coupled parabolic wave model. Thus, it is indicated that BWM can be applied to estimation of irregular wave transformations in complicated sea area such as reef accompanying with very shallow water area.
