TL;DR: In this paper, the reflection characteristics of vertical and sloping permeable seawalls were determined with a numerical model based on the methodology proposed by Ijima et al. (1976), and the variation of the reflection coefficients with the porosity of the wall, its friction factor and the relative wall width was compared with the analytical results of Madsen (1983).

TL;DR: In this paper, the time series of the onshore-offshore and the alongshore velocities obtained at different locations within a groin field and at a deeper location have been analyzed for wave directionality.
Abstract: The time series of the onshore-offshore and the alongshore velocities obtained at different locations within a groin field and at a deeper location have been analysed for wave directionality. For this purpose, seven different available methods along with a methodology proposed in this paper have been adopted to draw a comparative study, the results of which are presented and discussed in this paper. The variation of wave direction inside the groin field at a particular time and its variation along the depth are studied. The general wave climate and the flow characteristics in the groin field are also reported.
