  1. 11. Dagvattenhantering som katalysator för urbana ekosystemtjänster : ett gestaltningsförslag för Timboholmsparken i Skövde

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

    Author : Erik Borén; Olle Gillsjö; [2021]
    Keywords : dagvattenhantering; ekosystemtjänster; klimatanpassning; hållbar stadsutveckling; klimatförändringar;

    Abstract : De pågående klimatförändringarna är vår tids största globala utmaning. Global uppvärmning ökar risken för extremväder och redan nu kan vi bland annat se en ökande översvämningsproblematik runtom i världen. Översvämningsproblematiken blir särskilt påtaglig i de urbana områdena som sam-tidigt kan se en starkt ökande inflyttning. READ MORE

  3. 12. Implementation of Citizens’ Observations in Urban Pluvial Flood Modelling

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Fredrik Schück; [2021]
    Keywords : Calibration; Crowdsourcing; Citizen science; CDS-rainfall; 2D flood model; Spatial variability;

    Abstract : Damages caused by urban pluvial floods are believed to increase due to climate change and urbanization as more citizens are impacted in densely populated cities and extreme rainfalls occur more frequently with higher intensities. To prepare cities for these calamities, urban pluvial flood models are created to provide knowledge about how an extreme rainfall event could inundate the studied city. READ MORE

  4. 13. Rainwater Infiltration Model of the Chocaya Basin using Hydrus-1D

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Alexander Bergman; Mire Persmark; [2020]
    Keywords : Rainwater Infiltration; Alluvial Plain; Chocaya Basin; Hydraulic Conductivity; Double Ring Infiltrometer DRI ; Hydrus-1D; Electrical Resistivity Tomography ERT ; Earth and Environmental Sciences;

    Abstract : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. READ MORE

  5. 14. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Evangelos Oikonomopoulos; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

    Abstract : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. READ MORE

  6. 15. Snow depth measurements and predictions : Reducing environmental impact for artificial grass pitches at snowfall

    University essay from Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Author : Findlay Forsblom; Lars Petter Ulvatne; [2020]
    Keywords : artificial grass; rubber granulate pollution; snow depth measurement; snow level prediction; temperature index; energy index; energy balance model; machine learning; python; random forest; ultrasonic sensor; infrared sensor; lorawan; pycom lopy4; micro python; arduino uno; web application; javascript; node.js;

    Abstract : Rubber granulates, used at artificial grass pitches, pose a threat to the environment when leaking into the nature. As the granulates leak to the environment through rain water and snow clearances, they can be transported by rivers and later on end up in the marine life. Therefore, reducing the snow clearances to its minimum is of importance. READ MORE
