Waves attenuate rapidly as they propagate through porous media due to significant energy dissipation. The ability of permeable armour layers absorb wave is therefore great interest the researchers and engineers tasked with construction structures that defend vulnerable coastlines from attack. goal this research determine effectiveness vertical sloped barriers in minimising run-up. Traditional m...

an experimental study has been made of the hydrodynamics of a stage mixer-settler to obtain appropriate design information. in this paper several tests were done according to full factorial design of experiments with high reliability, since each test recurs seven times and the results of  them are very close to each other(p=1bar and t=25 °c). sauter diameter in each test is determined with phot...
