  1. 1. Use of Digital Image Correlation for monitoring of concrete buttress dam failure model tests

    University essay from KTH/Betongbyggnad

    Author : Jarl Jensen; Markus Leijström; [2022]
    Keywords : ;

    Abstract : The monitoring of dam structures is of great importance for the safety of the dam.A dam failure can cause disastrous consequences for people and infrastructure downstream.Dams are monitored by periodic inspections and monitoring systems. READ MORE

  3. 2. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

    University essay from Luleå tekniska universitet/Geoteknologi

    Author : Axel Barrdahl; [2022]
    Keywords : Non-hardening; Grout; Embankment dam; Repair; Fall cone; Uniaxial Compressive Strength; UCS; Triaxial;

    Abstract : Due to an increasing amount of aging tendencies in Swedish embankment dams, failures such as internal erosion has become a more common problem. Internal erosion is a phenomenon where certain soil material within the embankment dam is removed, often over a longer period of time. READ MORE

  4. 3. River-Aquifer Interaction in the Uppsala Esker - a Modelling Study of a Proposed Drinking Water Production site

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Kalle Kjellander; [2018]
    Keywords : Surface water-groundwater interactions; MODFLOW-model; Numerical model; Induced infiltration; Hydraulic conductivity; Grund- och ytvattenutbyte; MODFLOW-modell; numerisk modell; inducerad infiltration; hydraulisk konduktivitet;

    Abstract : The Swedish municipalities of Gävle and Älvkarleby need new sources of drinking water as the population grows. Gästrike vatten AB has employed the consultant firm Midvatten AB to assess the possibility of a new groundwater extraction site on the Uppsala esker between Älvkarleby and Skutskär in northern Uppland county.

  5. 4. Numerical Study on Seepage-induced Failure of Caisson Type Breakwaters Using a Stabilized ISPH

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Tetsuro Goda; [2017]
    Keywords : Tsunami; Breakwater; Particle method; SPH; Seepage flow; Technology and Engineering;

    Abstract : This paper presents a stabilized incompressible smoothed particle hydrodynamics (ISPH) method to simultaneously simulate surface and seepage flow. The Navier-Stokes type equation, which manipulates the linear and nonlinear resistance effects caused from porous materials, are employed for tracking fluid motions in porous medium. READ MORE

  6. 5. 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.
