  1. 1. Design and numerical analysis of an overflow section : a case study of Longtan dam

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Albin Wessling; Simon Jonsson; [2018]
    Nyckelord :Overflow section; design; FEM; stability;

    Sammanfattning : This thesis covers the master diploma work conducted at Hohai University, Nanjing, People's Republic of China. An overflow spillway section fitted for the Longtan Dam was designed and the loads acting on it was identified after an iterative flood routing calculation. LÄS MER

  3. 2. Urban flood modelling : a GIS based approach in Lomma, Skåne region

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Michael Araya Ghebremariam; [2017]
    Nyckelord :Physical Geography and Ecosystem analysis; Digital Elevation Model; Single flow direction algorithm; Deterministic eight-node D8 algorithm; Multiple flow direction algorithm; Triangular Form Based Multiple Flow algorithm TFM ; Earth and Environmental Sciences;

    Sammanfattning : Urbanization triggers flooding because it replaces pervious land surfaces with impervious surfaces that have less capacity to infiltrate and store water into the ground. Detailed analysis and modelling of flooding in urban areas can be performed with GIS-based distributed hydrological models. LÄS MER

  4. 3. Study on the Dynamic Control of Dam Operating Water Levels of Yayangshan Dam in Flood Season

    Kandidat-uppsats, KTH/Industriell ekologi

    Författare :Jenny Bramsäter; Kajsa Lundgren; [2015]
    Nyckelord :Yayangshan; Flood routing calculation; Backwater computation; HEC-RAS;

    Sammanfattning : Water levels up- and downstream of dams are strongly affected by water levels in the reservoir as well as the discharge of the dam. To ensure that no harm comes to buildings, bridges or agricultural land it is important to ensure that the water level in the reservoir is adjusted to handle large floods. LÄS MER
