  1. 1. Hydrodynamics of very shallow lakes - A study in Lake Krankesjön, Sweden

    Author : Charlotta Borell Lövstedt; Lund University.; Lunds universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alternative stable states; field measurements; reed; resuspension; wave damping; waves; differential heating; vegetation; convective currents;

    Abstract : Shallow lakes have great ecological and recreational values. They are also largely affected by humans, mainly through eutrophication, and great efforts are therefore being put into the understanding of these ecosystems. The knowledge is however not complete, and more research is needed to manage these lakes in a sustainable way. READ MORE

  2. 2. Interaction of Hurricanes and Natural Coastal Features: Implications for Storm Damage Reduction

    University dissertation from Lund University (Media-Tryck)

    Author : Ty Wamsley; Lund University.; Lunds universitet.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Louisiana; Barrier island; Vegetation; Flooding; Waves; Storm surge; Hurricanes; Mathematical modeling; Storm damage reduction;

    Abstract : It is generally acknowledged that wetlands and barrier islands can reduce surge and waves. However, while a general qualitative understanding of these interactions is available in the scientific literature, quantification of these interactions is lacking and has previously been based on limited data of relatively poor quality.

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

    University dissertation from Lund University (Media-Tryck)

    Author : Thanh Nam Pham; Lund University.; Lunds universitet.; [2010]
    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. 4. Swash Processes and Dune Erosion: Emphasis on Vessel-Generated Waves

    University dissertation from Lund University (Media-Tryck)

    Author : Li Erikson; Lund University.; Lunds universitet.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; marklära; kartografi; klimatologi; Civil engineering; hydraulic engineering; geomorfologi; Fysisk geografi; climatology; cartography; pedology; geomorphology; Naturvetenskap; Physical geography; Natural science; swash; erosion; vessel-generated waves; dunes; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : In navigable waterways, owing to the relatively short fetches for wind wave generation, the free waves generated by moving vessels often produce the dominant wave action with respect to erosion of the shore. In response to the fairly recent introduction of high-speed ferries, combined with a planned expansion within the passenger- and car-carrying ship market, the need to model and predict coastline changes as a result of exposure to vessel-generated waves has become a topic of increased research.

  5. 5. Water powered percussive rock drilling process analysis, modelling and numerical simulation

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Göran Tuomas; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : This thesis is devoted to problems, processes and systems related to the recently developed water powered percussive rock drilling method. The technology, which uses ordinary water to drive down-the-hole hammers, has been used to produce more than 6 million meters of blast holes within the mining industry. READ MORE
