  1. 11. How variations of the duration and time to peak of the Chicago Design Storm affect the hydraulic response, as well as the areas contributing to peak runoff, of a synthetic urban catchment area

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

    Författare :Oskar Ahlstedt; [2022]
    Nyckelord :Avrinningsområde; översvämningsmodellering; peak-bidragande område; hydrograf; hyetograf; MIKE 21; regnintensitet; CDS-regn; Chicago Design Storm;

    Sammanfattning : With an expanding urbanization in the world, and thus the expansion of impermeable surfaces, the risk of pluvial floods is an increasing factor that needs to be considered. This, in combination with increasing rain intensities and frequency of rain events indicates a problem both today and for the future. LÄS MER

  3. 12. Hydraulic Modeling and Quantitative Microbial Risk Assessment of Intrusionin Water Distribution Networks Under Sustained Low-Pressure Situations

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

    Författare :Maryam Shakibi; [2022]
    Nyckelord :drinking water distribution network; EPANET; hydraulic modelling; low pressure; pathogen intrusion; Quantitative Microbial Risk Assessment QMRA ; distributionsnät för dricksvatten; EPANET; hydraulisk modellering; lågtryck; patogen inläckage; Kvantitativ mikrobiell riskbedömning QMRA ;

    Sammanfattning : Drinking water systems aim to remove, reduce, and prevent microbial contamination in water by usingmultiple barriers from catchments to consumers. Water distribution networks are vulnerable tocontamination from external sources if they lose their physical or hydraulic integrity. LÄS MER

  4. 13. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Klara Lindqvist; [2022]
    Nyckelord :Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

    Sammanfattning : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. LÄS MER

  5. 14. Wetland Precipitationsheds : Assessing the Potential Vulnerability of 40 RAMSAR Wetlands to Upwind Land Cover and Hydroclimatic Change

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Simon Felix Fahrländer; [2022]
    Nyckelord :Wetlands; precipitationsheds; moisture import; moisture tracking; Lagrangian moisture tracking; land-atmosphere feedback;

    Sammanfattning : Wetland ecosystems play an important role in the global hydrologic cycle, and their hydrologicregime is a major factor for their general functioning (carbon, biodiversity, biogeochemicalcycle etc.). LÄS MER

  7. 15. Twenty-First Century Drought Projections in Swedish Catchments

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elise Jonsson; [2022]
    Nyckelord :Drought; climate change; drought index; climate models; catchments; societal functions; Torka; klimatförändring; torkindex; klimatmodeller; avrinningsområde; samhällsfunktioner;

    Sammanfattning : Droughts can have far-reaching and devastating effects on all sectors of society and ecology and future changes to drought and flood patterns are uncertain. This uncertainty has led to a lax response from local officials in dealing with mitigation and adaptation, particularly in Sweden. LÄS MER
