  1. 1. Surface Runoff on Green Urban Areas : A study on driving forces behind surface runoff generaiton

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Erik Nilsson; [2023]
    Nyckelord :Surface runoff; Hydrus; Urban green area; Soil Moisture;

    Sammanfattning : Recent flooding events, such as the one in Germany 2021 have caused irreversible damages to infrastructure and lives. The aftermath of events like these have underlined the importance of an accurate risk management by predicting them in urban areas. LÄS MER

  3. 2. Evaluation of rainfall-runoff modelling data in Sebeya Catchment, Rwanda - Recommendations for improved flood hazard analysis

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Anna Ebbersten; [2023]
    Nyckelord :Rwanda; Sebeya; hydrological modelling; rainfall-runoff; catchment; HEC-HMS; Technology and Engineering;

    Sammanfattning : Rwanda has experienced an increase in the frequency of riverine floods since the mid 2000s, and the future impact of climate change on the hydrological cycle is uncertain. Flood hazard analysis is one tool used to reduce flood risks; the analysis is often based on models which requires hydrological and meteorological data. LÄS MER

  4. 3. 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

  5. 4. The Influence of Infiltration Capacity and Antecedent Soil Moisture Conditions on Urban Pluvial Flooding

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Disa Barkefors; [2023]
    Nyckelord :Urban pluvial flood; 2D modelling; MIKE ; urban green area; soil moisture; Chicago Design Storm;

    Sammanfattning : Urban pluvial floods occur during extreme rain events and both occurrence and magnitude of these floods are expected to increase. Preserving or constructing green areas in urban areas has been shown to mitigate and control these floods. LÄS MER

  7. 5. Combining Continuous and Event-based Hydrological Modeling in Kävlinge River Basin with HEC-HMS

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Wenli Hu; [2022]
    Nyckelord :HEC-HMS; SCS-CN; Climate Change; GIS; Flood; Technology and Engineering;

    Sammanfattning : Prediction of flood and evaluation of the impact of climate change in a catchment needs to be correctly estimated, which can be accomplished by hydrological modelling in HEC-HMS. In this paper, the objectives were to gain an understanding of the rainfall-runoff process and estimate the flood frequency curve in the Kävlinge River Basin. LÄS MER
