  1. 1. 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

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

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

    Abstract : 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. READ MORE

  2. 2. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Eddie Blomström; [2022]
    Keywords : fishway; flow; hydraulics; HEC-RAS;

    Abstract : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. READ MORE

  3. 3. The influence of spatial variations in rain intensity for cloudburst modelling : a case study of the Gävle cloudburst

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fanny Jeppsson Stahl; [2022]
    Keywords : Flood modelling; pluvial flooding; spatial variations in rain intensity; design storms; MIKE 21 Flow Model FM; 2D hydraulic modelling; Skyfallsmodellering; pluviala översvämningar; spatiala variationer i regnintensitet; typregn; MIKE 21 Flow Model FM;

    Abstract : With an intensification of heavy rain events in a changing climate and a rapid urbanization the risk for pluvial flooding is increasing in our societies. Pluvial flooding, which is formed when the rainfall rate exceeds the infiltration or drainage rate, can occur rapidly and cause great damages, large economic losses and possibly risk human lives.

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

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

    Author : Maryam Shakibi; [2022]
    Keywords : 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 ;

    Abstract : 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. READ MORE

  5. 5. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ebba Pegestam; [2022]
    Keywords : Contaminant transport; Discrete Fracture Network; Geology; Geohydrology; Groundwater transport; Fracture; Drinking water; Contamination; Föroreningar; flödestransport; spricknätverk; geologi; geohydrologi; grundvattentransport; sprickor; dricksvatten;

    Abstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.
