چکیده
In this paper, a moving boundary technique is developed to investigate wave runup and rundown with depth-integratedequations. Highly nonlinear and weakly dispersive equations are solved using a high-order finite difference scheme. An eddyviscosity model is adopted for wave breaking so as to investigate breaking wave runup. The moving boundary technique utilizeslinear extrapolation through the wet–dry boundary and into the dry region. Nonbreaking and breaking solitary wave runup isaccurately predicted by the proposed model, yielding a validation of both the wave breaking parameterization and the movingboundary technique. Two-dimensional wave runup in a parabolic basin and around a conical island is investigated, andagreement with published data is excellent. Finally, the propagation and runup of a solitary wave in a trapezoidal channel isexamined. D 2002 Elsevier Science B.V. All rights reserved.
