  1. 1. Manning’s roughness coefficient in small scale nature-like fish passages

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Aleksander Jaworowski; [2022]
    Nyckelord :Manning’s coefficient; flow measurement; fish passage; fish migration; roughness coefficient; Technology and Engineering;

    Sammanfattning : Fishway construction remains a crucial measure in environmental adaption of flow barriers. A well-functioning fishway should be able to pass all naturally occurring species of fish and other aquatic fauna. LÄS MER

  3. 2. Improving stream flow estimation in a montane rainforest stream in Costa Rica : The impact of adding a high flow estimation

    Sammanfattning : A key piece of information necessary for water management is accurate streamflow information. However, the available data and resources for gathering information vary around the world. LÄS MER

  4. 3. Socioeconomic Impacts of Transitioning to Collaborative Port Operations - A case study of the Port of Gothenburg

    Master-uppsats, Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakulteten

    Författare :Axel Merkel; [2015]
    Nyckelord :Socioeconomic Impacts of Transitioning to Collaborative Port Operations;

    Sammanfattning : The purpose of this study is to derive a method for estimation of costs and benefits of implementing Port Collaborative Decision Making (Port CDM), and to apply this method to the Port of Gothenburg. By using the Port of Gothenburg as a case study, conclusions can be drawn regarding the economic viability of Port CDM in one of Scandinavia‟s largest ports. LÄS MER

  5. 4. Performance and uncertainty estimation of 1- and 2-dimensional flood models

    Magister-uppsats, Avdelningen för Industriell utveckling, IT och Samhällsbyggnad

    Författare :Nancy Joy Lim; [2011]
    Nyckelord :1D 2D flow models; flood; inundation study; GIS; GLUE; HEC-RAS; Manning’s coefficient; Telemac;

    Sammanfattning : Performance-based measures are used to validate and quantify how likely the system’s results resemble that of the actual data. Its application in inundation studies is performed by comparing the extents of the predicted flood to the real event by measuring their overlap size and getting the percentage of this size to the union of both data.
