  1. 1. Predicting inflow and infiltration to wastewater networks based on temperature measurements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Martin Åsell; [2024]
    Nyckelord :Inflow and Infiltration; I I; CNN; Linear regression;

    Sammanfattning : Sewer pipelines are deteriorating due to aging and sub optimal material selections, leading to the infiltration of clean ground and rainfall water into the pipes. It is estimated that a significant portion (up to 40-50%) of the water entering wastewater treatment plants is actually clean infiltrated water. LÄS MER

  3. 2. Soil compaction and the effect on infiltration in urban green environments : A study based on field measurements and HYDRUS 1D modelling

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Anastasia Novikova; [2023]
    Nyckelord :HYDRUS; surface runoff; soil compaction; urban environments;

    Sammanfattning : The consequences of recent flooding and extreme rain events have highlighted the importance of proper urban planning and preventative measures for storm water management. As cities become more urbanized the significance of permeable surfaces such as parks and other urban green spaces increases which infiltrate the water into the ground. LÄS MER

  4. 3. Evaluation of probabilistic forecasts in Uppsala and its potential use in winter road maintenance

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Elisabet Johansson; [2023]
    Nyckelord :forecast evaluation; ensemble system; MetCoOp; winter road maintenance; snow removal; utvärdering; ensembelprognos; MetCoOp; snöröjning; vinterväghållning;

    Sammanfattning : Efficient winter road maintenance is crucial for safety and societal function during the winter months in Sweden. This report aims to evaluate the MetCoOp ensemble system CMEPS and investigate its potential use as a basis for formulating criteria for snow removal that accounts for forecasted weather. LÄS MER

  5. 4. Inverse Atmospheric Dispersion Modeling in Complex Geometries

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Charlie Pelland; [2022]
    Nyckelord :atmospheric dispersion modeling; dispersion modeling; invers dispersion modeling; atmospheric dispersion; invers atmospheric dispersion; CFD; computational fluid dynamics; radioactive release; openfoam; CRBN; dry deposition; dry deposition velocity; scavenging effect; wet deposition; optimization model; Reynolds Averaged Navier-Stokes; adjoint mode; time-dependent rain simulation; time-dependent rain; time dependent rain simulation; time dependent rain;

    Sammanfattning : In the event of a radioactive release in an urban environment the consequent response mustbe swift and precise. As soon as first responders have correct information, they can make anaccurate risk assessment. However, if the position, release rate and time of the radioactiverelease is unknown it is hard to know how the pollutant will spread. LÄS MER

  7. 5. Hur nederbörd kan inverka på aktivitetsmönster och boskapspredation hos lejon (Panthera leo)

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Emma Berglund; [2022]
    Nyckelord :jaktlycka; lejon; Panthera leo; nederbörd; regn; aktivitetsmönster; predation; viltkonflikt; bytesdjur; boskap; vegetation;

    Sammanfattning : African lions (Panthera Leo) are classified as vulnerable according to the International Union for Conservation. The presence of predators as lion, is crucial for a functioning ecosystem worldwide, which makes the decline a serious problem. Wildlife conflicts between people and lions are a major threat for the lion population. LÄS MER
