  1. 16. Resistivity and Seismic Characterization of an Embankment Dam. A Case Study in Northern Sweden

    University essay from Uppsala universitet/Geofysik

    Author : Álvaro Polín-Tornero; [2018]
    Keywords : embankment dam; Sweden; ERT; seismic refraction; seismic reflection; modelling; jordfyllningsdamm; Sverige; ERT; seismisk refraktion; seismisk reflektion; modellering;

    Abstract : The main cause of failure in embankment dams - which represent 75% of all dams in the world (ICOLD, 2018) - is the internal erosion produced by excessive seepage not accounted for in their designs. This erosion can cause that a small anomalous structure, not likely to be considered as risky, turns rapidly into a significant structural damage if not recognized on time. READ MORE

  3. 17. Strukturkalkning av åkermark : ett sätt att minska jordbrukets bidrag till eutrofiering av vatten

    University essay from SLU/Dept. of Soil and Environment

    Author : Henrik Roth; [2018]
    Keywords : strukturkalkning; eutrofiering; fosfor;

    Abstract : In this review article, the effect of structural liming on clay soils, which have a high leakage potential for phosphorus (P), was analyzed. The purpose was to investigate structural liming as a method to reduce the impact of agriculture on eutrophication of water sources. READ MORE

  4. 18. Internal Erosion and Dam Stability : Analysis of the internal erosion effects on stability of an embankment dam

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Arthur Jedenius; [2018]
    Keywords : Internal erosion stability finite element analysis method plaxis slope seep;

    Abstract : Embankment dams encounter several problems in terms of dam safety. One of those problems is called internal erosion. This phenomenon is induced by the movement of fine particles within the dam due to seepage forces. If the dam is not able to self-heal, the eroded zones will increase which will eventually cause the dam to fail. READ MORE

  5. 19. The Anti-Tax Avoidance Directive and its Compatibility with Primary EU Law (Competence: Subsidiarity and Proportionality)

    University essay from Lunds universitet/Juridiska institutionen

    Author : Levan Maisuradze; [2017]
    Keywords : ATAD; BEPS; Compatibility; EU; Law; Direct; Taxation; Subsidiarity; Proportionality; Law and Political Science;

    Abstract : The EU has adopted to the anti-tax avoidance package to implement the OECD action plan on Base Erosion Profit Shifting. The Anti-Tax Avoidance Directive (ATAD) is a legislative element e of anti-tax avoidance package proposed by the Commission. READ MORE

  6. 20. Laboratory investigation of suffusion on dam core glacial till

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Daniel Yadetie Tuffa; [2017]
    Keywords : Internal erosion; Suffusion; Filter; Core; Glacial till; Embankment dam; Hydraulic gradients;

    Abstract : The objective of this study is to provide a better understanding of suffusion characteristics of glacial soils and to present a simple yet reliable assessment procedure for determination of suffusion in the laboratory.Internal erosion by suffusion occurs in the core of an embankment dam when the ability of the soil to resist seepage forces is exceeded and voids are large enough to allow the transport of fine particles through the pores.
