  1. 1. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

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

    Författare :Namika Maharjan; [2023]
    Nyckelord :Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Sammanfattning : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. LÄS MER

  3. 2. Analysis of Rainfall-runoff processes at different scales in two mountainous, Arctic catchments in northern Sweden

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :June Johansson; [2023]
    Nyckelord :Arctic hydrology; Catchment response parameters; Water height recession analysis; Permafrost presence; Glacier presence;

    Sammanfattning : The hydrological regime in Arctic catchments is being altered as an effect of climate change. To be able to project future changes in Arctic hydrology and hydrogeology, the mechanisms and drivers affecting runoff generation needs to be understood. LÄS MER

  4. 3. Sensitivity analysis of a generic urban flow model : 2D modelling with empirical hyetographs and CDS rain

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Julia Granlund; [2022]
    Nyckelord :Input parameters; initial water content; antecedent moisture content; impervious surfaces; topography; empirical hyetographs; design storms;

    Sammanfattning : Severe flooding events in recent years have underlined the importance of accurate hydrological modelling in urban areas. There are many important parameters relating to both the rainfall distribution and properties of the land on which the rain falls that controls the impacts of the rain event. LÄS MER

  5. 4. Developing a Rainfall-Runoff Routing Model using  Spatially Distributed Travel Times : Modelling a Cloudburst Event in an Urban Catchment

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Sara Ekeroth; [2022]
    Nyckelord :Excess rainfall; Runoff routing; Cloud burst; Pluvials; GIS; ArcPy; Effektiv nederbörd; Avrinningsmodell; Skyfall; Pluviala översvämningar; Geodata; ArcPy;

    Sammanfattning : The future holds challenges for urban areas when it comes to handling pluvial floodings, occurring when the rainfall intensity exceeds both the man-made and natural infiltration and drainage capacity. To gain understanding of the effects and needed measures, tools for modelling the urban response to events such as cloudbursts are needed. LÄS MER

  7. 5. A Nonlinear Reservoir Model to Simulate Blue-Green Stormwater Systems – An Application to Augustenborg Catchment in Malmö, Sweden

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Emmanuel Ekwu; [2021]
    Nyckelord :Blue-green stormwater control; Nonlinear reservoir routing model; Stormwater; Modelling; Calibration; Water engineering; Technology and Engineering;

    Sammanfattning : The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. LÄS MER
