  2. 1. Numerical Model of Beach Topography Evolution due to Waves and Currents: Special Emphasis on Coastal Structures

    Author : Thanh Nam Pham; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; morphodynamics; surface roller; wave-induced currents; random waves; sediment transport; coastal structures;

    Abstract : The beach topography change in the nearshore zone may be induced by natural phenomena such as wind, wave, storm, tsunami, and sea level rise. However, it can also be caused by man-made structures and activities, for example, groins, detached breakwaters, seawalls, dredging, and beach nourishment. READ MORE

  4. 2. Ultimate and Residual Strength Assessment of Ship Structures

    Author : Artjoms Kuznecovs; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ship structures; collision; corrosion; residual strength; ultimate strength; age-related degradation; nonlinear FEA; Smith method;

    Abstract : The prevention of ship structural failures and reduction of accident consequences contribute to increased safety at sea and reduced environmental impact. A need for reliable and efficient ship designs facilitates knowledge accumulation and the development of tools for the assessment of hull structural responses to acting loads. READ MORE

  5. 3. Long-Term Simulation of Coastal Evolution

    Author : Hoan Le Xuan; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tidal inlet; inlet shoal; sediment transport; spit growth; shoreline change; spit model; inlet model; mathematical model; numerical model; shoreline model;

    Abstract : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. READ MORE

  6. 4. Shipworm ecology in Swedish coastal waters

    Author : Christin Appelqvist; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Shipworms (Teredinidae) are marine bivalves adopted for boring into submerged wood, which they efficiently fragmentize and consume. They thereby perform a vital ecosystem service, yet simultaneously they cause extensive damage to important man-made marine structures. READ MORE

  7. 5. Ecology and evolution of coastal Baltic Sea 'dead zone' sediments

    Author : Elias Broman; Mark Dopson; Nils Risgaard-Petersen; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; sediment; oxygen; metatranscriptomics; metagenomics; 16S rRNA gene; RNA-seq; dead zone; re-oxygenation; Akvatisk ekologi; Aquatic Ecology;

    Abstract : Since industrialization and the release of agricultural fertilizers began, coastal and open waters of the Baltic Sea have been loaded with nutrients. This has increased the growth of algal blooms and because a portion of the algal organic matter sinks to the sea floor, hypoxia has increased. READ MORE
