  1. 1. Evaluating an increased spill regime as a management tool to improve downstream passage of salmon smolt

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Mattias Hansson; [2022]
    Keywords : hydraulic modeling; hydroacoustic telemetry; time to event analysis; hydraulisk modellering; överlevnadsanalys; hydroakustisk telemetri;

    Abstract : The anadromous Atlantic salmon (Salmo salar) is dependent on river connectivity to reach spawning and rearing habitats in rivers. Most rivers are today fragmented by artificial barriers such as hydroelectric powerplants (HEP) which impede this migratory movement. READ MORE

  3. 2. Modeling of a Hydraulic Rock Drill for Condition Monitoring

    University essay from Linköpings universitet/Fordonssystem

    Author : Adam Kagebeck; Mahdi Najafi; [2022]
    Keywords : Condition Monitoring System; Hydraulic Rock Drill; Diagnostic; Modeling; State Space Model;

    Abstract : This thesis aims to investigate the possibility of using a mathematical model to detect several common faults in a hydraulic rock drill. To this end, a parameterized state space model of the hydraulic drill, which simulate its behavior, is created. READ MORE

  4. 3. 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

  5. 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

  6. 5. Modelling the Human-Flood Interactions : Effects of different societal risk perceptions on flood losses

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Zhixian Hu; [2022]
    Keywords : Socio-hydrological modelling; risk perception; flood risk management; Sociohydrologisk modellering; riskperception; hantering av översvämningsrisk;

    Abstract : Can one society’s flood risk perception and management strategy impact the neighbouring society? This study applies a socio-hydrological model to four ideal types of society living along the same river. These societies have various rationalities and risk perceptions: risk-controlling, risk-monitoring, risk- neglecting and risk-downplaying. READ MORE
