COUPLED VIBRATION EQUATIONS FOR IRREGULAR WATER WAVES

Masao Nochino

Abstract


A new system of equations is proposed for calculating wave deformation of irregular waves under the assumption of small amplitude wave and of mild slope of bottom configuration. The system is composed of a vibration equation for water surface elevation and three elliptic equations defined in horizontal plane. These equations are coupled each other. The coupled vibration equations are capable of calculating water surface elevation of irregular waves in a time domain.
