  1. 1. 2D Reflection Seismic Imaging of Sparse 3D Data in the Zinkgruvan Mine, Central Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maryam Abbasian; [2021]
    Keywords : 2D crooked-line; reflection seismic; sparse 3D; mineralization; Zinkgruvan; 2D modellering; reflektionsseismik; mineralisering; Zinkgruvan;

    Abstract : Zinkgruvan mining area in the southern Bergslagen mineral district of central Sweden holds over 30 million tons of massive sulphide mineralization. The ever-increasing global demand for mineral/metal resources, together with metal consumption growth especially for high-tech purposes has made the exploration of these resources of particular importance.

  3. 2. 2D Modelling of Geosynthetically Reinforced Piled Embankments : Calibration Methods in PLAXIS 2D & Review of Analytical Guidelines

    University essay from KTH/Jord- och bergmekanik

    Author : Maya Sleiman; [2021]
    Keywords : ;

    Abstract : This thesis focuses on the 2D modelling of Geosyntheticaly Reinforced Piled Embankments (GRPE) in PLAXIS 2D. In doing so, it explores two main aspects: 1) the calibration of Interface Stiffness Factors (ISFs) governing the soil-pile interaction of Embedded BeamRow (EBR) elements in PLAXIS 2D, and 2) the prospects and limitations of modelling geogrids (GR) in PLAXIS 2D when underlain by EBR elements; although several studies have validates the EBR element in modelling piles, none address the geogrid-EBR interaction and its implications on modelling GRPE systems.

  4. 3. Nutrients spreading with cloudburst modeling

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Nikita Smiyanov; [2020]
    Keywords : MIKE21; 2D-modeling; nutrients; phosphorus; nitrogen; cloudburst; land-use; MIKE21; 2D-modellering; närsalter; fosfor; kväve; skyfall; markanvändning;

    Abstract : Climate change and environmental disasters are strongly dependent. Humanity is facing considerable changes in environmental adaptions and remediation of contaminated sites. Water is a valuable resource that should be protected and prevented from hazardous influences. READ MORE

  5. 4. 2D Effects of Geomorphology and Discharge on Hyporheic Exchange—a HEC-RAS Modelling Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Olivia Preston; [2020]
    Keywords : average hyporheic exchange velocity; water surface elevation; water surface concavity; hydrostatic head;

    Abstract : Hyporheic exchange is an ecologically and biogeochemically essential function of rivers and streams. One important driver of hydrostatic (hyporheic) exchange is gra- dients in the hydrostatic hydraulic head at the streambed. READ MORE

  6. 5. The influence of storm movement and temporal variability of rainfall on urban pluvial flooding : 1D-2D modelling with empirical hyetographs and CDS-rain

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Jimmy Olsson; [2019]
    Keywords : pluvial flooding; flood modelling; 1D-2D modelling; MIKE FLOOD; MIKE 21; MIKE URBAN; storm movement; temporal variability; hyetograph; design storm; Chicago Design Storm; CDS-rain; pluviala översvämningar; översvämningsmodellering; 1D-2D modellering; MIKE FLOOD; MIKE 21; MIKE URBAN; molnrörelse; hyetograf; typregn; Chicago Design Storm; CDS-regn;

    Abstract : Pluvial floods are formed directly from surface runoff after extreme rain events. Urban areas are prone to suffer from these floods due to large portions of hardened surfaces and limited capacity in the stormwater infrastructure. Previous research has shown that catchment response is influenced by the spatio-temporal behaviour of the rainstorm. READ MORE
