A history of the Breakwater Prison from 1859 to 1905
… or "austere" institution is the prison. The Breakwater convict station, a colonial prison in Cape Town during the nineteenth century, suited both my theoretical and empirical interests. I chose this particular institution because it was the prison from which the linguist W.H.I. Bleek drew his …

Cape of storms Cabo das Tormentas : exploring natural events at the Breakwater
This project is about uncovering natural events in the Cape Town Harbour landscape.

Breakwater Enhancement: Redesign Tetrapod Structures for Resilient Coastal Environments and Marine Ecosystem Rehabilitation
Global coastal erosion, exacerbated by climate change, poses a pressing threat with widespread repercussions, necessitating innovative and sustainable solutions. Tetrapod structures, while effective in coastal defense, suffer from their drawbacks, including substantial carbon emissions from …

Three-Dimensional Nonlinear Dynamics of a Moored Cylinder to be Used as a Breakwater
… submerged, rigid, solid cylinder to be used as a breakwater. The breakwater could potentially be used as a single cylinder to protect small structures. Alternatively, multiple cylinders could be positioned in series to protect shorelines, harbors, or moored vessels from destructive incident water …

A study of breakwater gap wave diffraction using close range photogrammetry and finite and infinite elements.
… of water waves passing through a gap in a breakwater is investigated experimentally, using close range photogrammetry, and numerically, using finite and infinite elements. The author was particularly interested in validating specific breakwater gap diffraction diagrams given in popular …

Investigation Into Snap Loading of Cables Used in Moored Breakwaters
… dynamic analysis is conducted on a moored breakwater configuration to investigate snap loads in mooring lines. Breakwaters are structures used to attenuate or eliminate waves and protect shorelines, harbors, and other natural and man-made marine structures from wave damage. The breakwater …

Storm warning: a theatre of atmospherics
… of a Theatre of Atmospherics located at the main breakwater of Cape Town harbour. This Theatre consists of four elements;, _a weather device; _a research facility for the South African National Antarctic Programme (SANAP); _a 'shifting' communal space for the research facility; and the theatre …

Power extraction from an oscillating water column along a coast
… Column (OWC) is attached to the tip of a long breakwater. A three-dimensional numerical model of a skeletal geometry of the the Foz do Douro breakwater is developed in order to determine the response inside the OWC pneumatic chamber to incident waves and assess the possible effects of the …

Three-Dimensional Analysis of Moored Cylinders Used as Breakwaters
… frequencies, the use of moored cylinders as breakwaters is considered numerically using linear three-dimensional analysis. The breakwater can be used by itself for protection of small structures or as a series of cylinders to protect a harbor, shoreline, or moored vessel from the destructive …

Experimental Analysis of the Interaction of Water Waves With Flexible Structures
… water waves with flexible structures acting as breakwaters was carried out. Wave profiles, mapped out by water level measuring transducers, were studied to provide information on the performance of different breakwater models. A new signal analysis procedure for determining reflection …

Finite element analysis of cellular structures subjected to wave loads
… used as permanent retaining walls, navigation or breakwater structures. When used as breakwaters, the metal fatigue can become a possible mode of failure for cellular structures due to the cyclic unbalanced lateral loads imposed by the wave action;This study was initiated as an investigation of …

An investigation of bottom changes in Monterey harbor (1932-1969).
… in the beach and nearshore zones and along the breakwater; and less than 0.25 feet per decade in the stable outer harbor. The accretion rate averaged 17,500 cubic yards per year from 1932-1969 but only 7,100 cubic yards per year from 1947 to 1969. The shoaling is believed due to the construction …

Mitigating Compute Congestion for Low Latency Datacenter RPCs
… resources. This thesis introduces two systems, Breakwater and LDB, designed to mitigate and diagnose compute congestion, each targeting different sources of tail latency. Breakwater aims to alleviate CPU congestion and lock contention during intermittent server overload, while LDB furnishes …

Wave reflections from breakwaters
… acquired offshore of a permeable, rubble mound breakwater in Monterey Bay, California. The estimated reflection coefficients decrease approximately linearly with creasing frequency. Whereas the observed reflections depend only weakly on the incident wave energy, the fraction of the incident wave …

Green water and loading on high speed containerships
… was also conducted on a series of rectangular breakwaters that were fitted on the forecastle deck. Changes in water behaviour and loading following changes in the breakwater were well reflected. This implied that instead of a rectangular breakwater, the simulation model could also be applied to …
