  1. 6. Fördröjning och rening i urbana dagvattenlösningar : undersökningar av krossmagasin med kolmakadamfyllning i Rosendal Etapp 1 samt Gamla Uppsalagatan 21:20

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Marlene Nilsson; [2022]
    Keywords : biokol; dagvatten; metall adsorption; hållbara dagvattenhantering; reningsförmåga; first flush; svackdike; makadamdike; avsättningsmagasin;

    Abstract : Klimatanpassning av urbana miljöer är en stor utmaning som samhället står inför. Att ta hand om dagvattenavrinning när regnen blir intensivare och flödestopparna större gör att de underdimensionerade ledningsnätet inte räcker till för dessa flöden. READ MORE

  3. 7. An automated unmanned aerial vehicle – structure from motion pipeline to create analysis-ready digital surface models for coastal monitoring

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Maximilian Rafael Huber; [2021]
    Keywords : physical geography; ecosystem analysis; geomatics; GIS; UAV; structure-from-motion; machine learning; coastal monitoring; Earth and Environmental Sciences;

    Abstract : Anthropogenic pressure on coastal areas continues to increase, thus intensifying coastal erosion. Coastal monitoring programs are therefore essential to prevent severe ecosystem and economic consequences. Successful coastal monitoring schemes require highly accurate analysis-ready Digital surface models (DSMs) derived using the same workflow. READ MORE

  4. 8. Metal Removal Efficiency of Five Filter Media Intended for use in Road Stormwater Treatment Facilities

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Lovisa Lundgren; [2021]
    Keywords : Stormwater; Metal removal efficiency; Filter media; Dagvatten; Metallavskiljningskapacitet; Filtermaterial;

    Abstract : Roads, buildings, vehicles, and human activities cause spreading of pollutants, which partly end up in stormwater. The pollutant load contains solid particles of various size, hydrocarbons, organics, metals, nutrients, and microorganisms, which can have negative effects on water quality of surface-, coastal- and ground waters.

  5. 9. Design and Optimisation of an Aquifer Storage and Recovery System - Options for long term storage under natural hydraulic gradients

    University essay from Lunds universitet/Teknisk geologi

    Author : Simon Kreipl; [2021]
    Keywords : Aquifer storage and recovery; well-field design; groundwater modelling; numerical modelling; FEFLOW; Technology and Engineering;

    Abstract : Aquifer storage and recovery (ASR) is a concept where water is stored in an aquifer during times when it is available, thus creating artificial groundwater, which can later be recovered by pumping when it is needed (Pyne, 1995). One ASR cycle consists of a injection, a standby and a recovery phase. READ MORE

  6. 10. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Ines Júlio Alfredo; [2021]
    Keywords : Sentinel 2; Vegetation Indices; Ground Sensors; Drought and Mire; Earth and Environmental Sciences;

    Abstract : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. READ MORE
