摘      要：The main objective of this paper is to examine the influences of both the principal wave direction and the directional spreading parameter of the wave energy on the wave height evolution of multidirectional irregular waves over an impermeable sloping bottom and to propose an improved wave height distribution model based on an existing classical *** numerical model FUNWAVE 2.0,based on a fully nonlinear Boussinesq equation,is employed to simulate the propagation of multidirectional irregular waves over the sloping *** of wave heights derived from wave trains with various principal wave directions and different directional spreading parameters are *** show that both the principal wave direction and the wave directional spread have significant influences on the wave height evolution on a varying coastal *** shoaling effect for the wave height is obviously weakened with the increase of the principal wave direction and with the decrease of the directional spreading *** the simulated data,the classical Klopman wave height distribution model is improved by considering the influences of both *** is found that the improved model performs better in describing the wave height distribution for the multidirectional irregular waves in shallow water.
