Applied hydromechanics, Vol. 8 (80) ¹ 1, (2006) p.73-78
The influence of regular bottom peaks or incline part of bottom surface on suppression of surface gravity waves on the basis of potential theory in the framework of the model of finite depth water is investigated. For solving the problem in the region of variable depth the method of spline-collocation is used. The influence of the number of local peaks and their hight on the reflexion coefficient is investigated. Also, the influence of inline part or inlcline polygonal part is investigated. The analysis of characterictic features of the phenomenon and the possibility of effective wave suppression are presented.
