DYNAMIC RESPONSE OF SEABED-RUBBLE MOUND BREAKWATER SYSTEM UNDER SEISMIC WAVES M. B. Can ÜLKER1 ABSTRACT In the design of coastal structures, evaluation of dynamic response and stability of foundation materials is important. One of the major concerns related to these structures is the response of the. Today, rubble mound breakwaters are used mainly for coastal protection or construction of harbour basins. For these structures, the typical wave conditions are breaking waves on shallow water. However, the typical design tools are mainly based on physical model tests with deep water wave conditions.
What is Breakwater? • A structure protecting a shore area, harbor, anchorage or basin from wave disturbance. • A barrier that breaks the force of waves, as before a harbor. • Breakwaters are structures constructed on coasts as part of coastal defense or to protect an anchorage from the effects of both weather and long shore drift. 3. A rubble mound breakwater with slopes and with an Xbloc armour layer covering front slope, crest and rear slope was tested (Fig. 3). The seabed slope in front of the structure was The water depth at the breakwater toe was cm and was constant to ensure consistent wave conditions for all tests.

An undistorted-scale hydraulic model study was conducted to investigate the armor stability and wave-transmission design of three breakwater cross sections for Port Ontario Harbor, New York. Plan 1 was constructed to a crown elevation of +10 ft lwd and used armor slopes of IV on 2H and 1V on H lake-side and harbor side, respectively.

The breakwater armour layer consisted on Antifer cubes double layer. In breakwater B, the colours of the blocks (Fig. 7) are of utmost importance on the detection of armour layer damages during the tests.
Rubble mound breakwaters have probably existed for around years and modern coastal engineers still build them to create harbours sheltered from wave action. Some ancient breakwaters are still well preserved today, while many others are now eroded and submerged as a consequence of thousands of years of storms and wave activity.
The stability number of a breakwater can determine the armor unit’s weight, which is an important parameter in the breakwater design process. In this paper, a novel and simple machine learning approach is proposed to evaluate the stability of rubble-mound breakwaters by using Extreme Learning Machine (ELM) models.
The data-driven stability assessment models were built based on a small. 5 1. RUBBLE MOUND BREAKWATER. GENERAL DESIGN PRINCIPLES (from AU Port Engineering) Introduction Rubble mound breakwaters are used.

insufficient for the tested conditions with long waves. A new stability formula is presented based on the new model tests and adjusted to fit earlier stability tests.
The next subject treats the stability of berm breakwaters, where previous studies have shown a trend similar to the conventional rubble mound breakwater for short waves.

13 Jackson, R. Stability measurements on rubble-mound breakwaters. Coastal Eng., 2: This paper describes methods and equipment for testing the stability of rubble-mound breakwaters. One instrument, called the OBDS (Optical Break-Down Sensor), is intended for global evaluation of the break-down process as a function of time.
Rubble mound breakwaters are used in a variety of locations. They can be used to protect anchorages as shown in the photograph to the left as well as parallel or perpendicular to shorelines as shown in the photographs at the top of this page (Ranasinghe et al., ). 8. Summary and conclusion.
Wave height is the most important parameter in the prediction of structural response of breakwaters. In this study, the effect of using H 50, the average of the 50 highest waves that reach the breakwater, in the prediction of stability number of rubble-mound breakwater wasEB's formulas were modified successfully by using H 50 instead of .Full Scale Measurements of Wave Attenuation Inside a Rubble Mound Breakwater At the Zeebrugge harbour (Belgium) a cross-section of the N.W.-breakwater has been instrumented for the study of physical processes related to the behaviour of a prototype rubble mound breakwater in random wave conditions.
Rubble-Mound Breakwater Stability.The stability of a rubble mound breakwater is usually described by the "zero damage" design sea state, allowing still some small armour movements if they do not exceed some limits. According to a number of regular wave tests with no overtopping, that stability is a function of the dimensionless Hudson stability number, NS, given by, SS S 1/3.
