N2 - The problem of the interaction of a solitary wave with a partially immersed fixed body over an irregular bottom is considered. This problem is solved using the nonlinear dispersive shallow-water (Serre–Green–Naghdi) model and the potential flow model. The influence of the horizontal and vertical sizes of bottom irregularities and their location relative to the partially immersed body on the values of the total force acting on the body is studied numerically. It is shown that the horizontal component of this force increases monotonically with increasing vertical dimension and length of the underwater obstacle. This effect is enhanced when approaching the body. The vertical component of the force is slightly affected by the obstacle, and its dependence on the obstacle size may be nonmonotonic.
