  1. 11. Structural intrusion, flow disturbance and spillway capacity : CFD modeling of the Torpshammar dam

    University essay from Uppsala universitet/Elektricitetslära

    Author : Adéle Wallin; [2018]
    Keywords : RNG k-ε model; VOF; Fluent; turbulence; rectangular beams; flow pattern; discharge capacity; flow velocity;

    Abstract : At the Torpshammar dam two rectangular beams are situated upstream of the spillway gates to stabilize the sidewalls holding the embankment of the dam. A computational fluid dynamics (CFD) simulation of the dam with the bottom outlets open was made to investigate how the flow and discharge capacity is affected by the beams. READ MORE

  3. 12. Designing Roller compacted concrete (RCC) dams

    University essay from KTH/Betongbyggnad

    Author : Shayma Al Baghdady; Linnea Khan; [2018]
    Keywords : Roller Compacted concrete; Massive concrete structures; Dams; Concrete;

    Abstract : Concrete is the most common building material in the world and it consists of aggregates,cement and water that harden over time, it is also known as a composite material. The use ofconcrete is very versatile due to its resistance to wind and water and its ability to withstandhigh temperature. READ MORE

  4. 13. 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. 14. Determination of dry density in tailings with a Dynamic Cone Penetrometer :

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

    Author : Patrik Hagström; [2017]
    Keywords : dynamic cone penetrometer; tailings dam; tailings beach; tailings;

    Abstract : Today mines produce metals which are used for everyday products by people worldwide. When metals are produced, waste products known as tailings are generated. These tailings are commonly stored in impoundments, surrounded by embankment dams. The demands from the society are constantly increasing regarding the quality and safety of dams. READ MORE

  6. 15. 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.
