  2. 11. Landslide of contaminated soil into rivers: Environmental impacts and risks

    Author : Gunnel Göransson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contaminated soil; landslide; risk assessment; river; water quality;

    Abstract : Landslide risk assessments and environmental risk assessments are routinely carried out in many countries exposed to landslide hazards and/or contaminated soil hazards, but separately from each other. By combining results from different types of risk assessments and superimposing the results, possible multi-hazards may be revealed, which is not the case when the results are only displayed independently.

  4. 12. Loads and responses for planing craft in waves

    Author : Anders Rosén; Dan Zenker; Brian Hayman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; planing craft; high-speed craft; waves; model tests; sull-scale trials; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Abstract : Experimental and numerical analysis of loads and responses for planing craft in waves is considered. Extensive experiments have been performed on a planing craft, in full-scale as well as in model scale. The test set-ups and significant results are reviewed. READ MORE

  5. 13. Waves and instabilities through the lens of asymptotic analysis

    Author : Anthony Bonfils; John Wettlaufer; Dhrubaditya Mitra; Woosok Moon; Jerome Neufeld; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; waves; wrinkles; instabilities; Theoretical Physics; teoretisk fysik;

    Abstract : Understanding the interaction of water waves with winds and marine currents is a fundamental problem in geophysical fluid dynamics. From the point of view of hydrodynamic stability, surface waves are regarded as perturbations of an inviscid parallel shear flow modeling the wind in the air and the current in the water. READ MORE

  6. 14. Propeller-Hull Interaction Effects in Calm Water and Regular Head Waves

    Author : Mohsen Irannezhad; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RANS; Resistance; Thrust Deduction Factor; Self-Propulsion Point of Model; CFD; Regular Head Waves; Nominal Wake; Ship Motions; Taylor Wake Fraction; Propeller Open Water Characteristics; EFD; FNPF;

    Abstract : In order to design fuel-efficient ships and install compatible propulsion systems, ship and propeller designers need to know the potential effects of the interactions between different ship components, e.g., hull, propeller, appendages and machinery, on the ship performance at sea.

  7. 15. Time Simulation of the Behaviour of Damaged Ships in Waves

    Author : Martin Schreuder; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waves; SIMCAP; seakeeping; ship; damage; stability; dynamics;

    Abstract : The cause of event and ability for ship survival after damage are in many cases poorly described by pure static considerations. The dynamic properties of the ship and environment will be significant in the assessment of the damage scenario. Physical theories describing these properties have been developed since many decades.
