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

    Författare :Charlotta Borell Lövstedt; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alternative stable states; field measurements; reed; resuspension; wave damping; waves; differential heating; vegetation; convective currents;

    Sammanfattning : 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. LÄS MER

  3. 2. Long-term beach and dune evolution : Development and application of the CS-model

    Författare :Caroline Hallin; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coastal processes; sediment transport; numerical modelling; Ängelholm Beach; Kennemer Dunes;

    Sammanfattning : Coastal flooding and erosion are worldwide problems that are further aggravated by rising sea levels and increasing population densities in coastal areas. In many of those areas, sandy beaches and dunes protect thehinterland from waves and extreme water levels during storms, while providing natural and recreational values. LÄS MER

  5. 4. Hygiene Aspects of Greywater and Greywater Reuse

    Författare :Jakob Ottosson; KTH; []
    Nyckelord :greywater; greywater reuse; greywater treatment; microbial risk assessment; groundwater recharge; irrigation; recreational water; faecal contamination; indicator bacteria; index organisms; faecal sterols; bacteriophages; enteric pathogens; rotavirus; ;

    Sammanfattning : Greywater is domestic household wastewater without inputfrom the toilet, i.e. wastewater from sinks, the shower,washing machine and dishwasher in a home. Source separation ofgreywater can be a strategy to enhance recirculation of plantnutrients and/or improve water use. LÄS MER

  7. 5. Immersion and recreational boating-related injuries in Alaska

    Författare :Diana Stark Hudson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alaska; injuries; drowning; cold water; immersion; submersion; hypothermia; survival;

    Sammanfattning : Background: Cold water is an ever-present hazard in Alaska, and when water-related injuries occur, they often take place in remote environments, where the nearest trained emergency response teams are several hours away. Alaska’s crude drowning death rate in 2002 was 4. LÄS MER
