A numerical model for run-up of breaking waves

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Numerical modeling of wave propagation, breaking and run-up on a beach

A numerical method for free-surface flow is presented at the aim of studying water waves in coastal areas. The method builds on the nonlinear shallow water equations and utilizes a non-hydrostatic pressure term to describe short waves. A vertical boundary-fitted grid is used with the water depth divided into a number of layers. A compact finite difference scheme is employed that takes into acco...

A numerical study of submarine-landslide-generated waves and run-up

A mathematical model is derived to describe the generation and propagation of water waves by a submarine landslide. The model consists of a depth-integrated continuity equation and momentum equations, in which the ground movement is the forcing function. These equations include full nonlinear, but weak frequencydispersion, e¬ects. The model is capable of describing wave propagation from relativ...

Run-up amplification of transient long waves

The extreme characteristics of the run-up of transient long waves are studied in this paper. First we give a brief overview of the existing theory which is mainly based on the hodograph transformation [9]. Then, using numerical simulations, we build on the work of Stefanakis et al. (2011) [37] for an infinite sloping beach and we find that resonant run-up amplification of monochromatic waves is...
