  1. 1. Assessment of a sediment management solution in a reservoir with a sluicing technique using a HEC-RAS 2D model : Case study of Andakílsá river in west Iceland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Emilía Sól Gudgeirsdóttir; [2023]
    Keywords : SediCon Sluicer; Andakílsá Hydropower Station; HEC-RAS 2D Sediment modelling; Sustainable sediment management; SediCon Sluicer; Andakílsá vattenkraftverk; HEC-RAS 2D Sediment Modellering; Hållbar sedimenthantering;

    Abstract : Sediment-related issues in reservoirs can often pose significant challenges to their operational effectiveness, sustainability, and environmental impact. Sustainable sediment management can help resolve these issues and extend the lifespan of dams. READ MORE

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  4. 3. Study of the Dilution of a chemical spill through tracer experiments in The Käppala Association's Sewerage Network, Stockholm

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Jerome Scullin; [2021]
    Keywords : Sewerage network; Tracer tests; Solute transport; ADE; Breakthrough curve; Uranine;

    Abstract : Wastewater treatment plants (WWTPs) play a vital role in protecting the environment from much of the waste produced by humans. This includes not only human waste, but everything that makes its way into a sewerage system including greywater, stormwater, and potentially hazardous chemicals from, inter alia, chemical spills.

  5. 4. Satellite derived data to support flood modelling : An application to the Po River

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Victor Alejandro Ortiz Peña; Milos Dinic; [2018]
    Keywords : Hydraulic Modelling; Flood Modelling; HEC-RAS; Mannings Coefficient; DEM; LiDAR; SRTM; Virtual Stations;

    Abstract : Satellite derived data has become an essential input in hydraulic modelling. Digital ElevationModels (DEMs) derived from different sources through remote sensing techniques have become a powerful tool for poorly gauged regions. READ MORE

  6. 5. Seasonal Variations of Manning’s Coefficient Depending on Vegetation Conditions in Tärnsjö, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Rūta Plakane; [2017]
    Keywords : Manning’s roughness coefficient; vegetation; HEC-RAS; Tärnsjö; uncertainty; rating curve; Manning råhetskoefficient; vegetation; HEC-RAS; Tärnsjö; osäkerhet; ratingkurva;

    Abstract : Hydrological models are used widely and they demand for multiple input variables and observations. One of those variables is Manning’s roughness coefficient. In the current literature the variability of the coefficient poses an unknown uncertainty. READ MORE
