The crest level of coastal structures such as dikes and breakwaters is often based on estimates the amount wave overtopping. One important parameters affecting overtopping angle incident waves since oblique can significantly reduce compared to perpendicular attack. Based 3D physical model tests dikes, rubble mound vertical caisson breakwaters, influence attack has been evaluated. A new expressi...

The design and the construction were carried out by installing new caissons on back or front of existing to increase structural stability caisson breakwaters. In this study, we used ANSYS AQWA program analyze wave forces acting individual according effects wave-structure interaction when additionally installed force characteristics analyzed distance among in frequency domain analysis. addition,...

was to inflate the tunnel, as you would blow up a bladder, by corking up one end with a huge brick wall twelve feet thick and pumping in additional atmospheres. At the sea level the pressure of the atmosphere is well known to be about fifteen pounds per square inch ; but into this air-tight chamber the engineers pumped sometimes as much as an additional thirtyfive pounds to the square inch, so ...
