  1. 26. The Effects of Erosion-control Structures and Gully Erosion on Groundwater Dynamics Along the Kromrivier, Eastern Cape, South Africa

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Vincent de Haan; [2016]
    Keywords : Gully erosion; wetland; groundwater dynamics; erosion-control structures;

    Abstract : The Palmiet wetlands located along the Kromrivier in the Eastern Cape province of South Africa have experienced severe degradation through gully erosion during the past decennia which has been threatening the water quality and water security of large towns in the Nelson Mandela Metropolitan hub. Water scarcity is a growing problem in this region as a result of land degradation and growing erratic rainfall patterns. READ MORE

  3. 27. Quality of CPTU : Analyses and comparison of data from commercial actors in Stockholm/Mälardalen

    University essay from KTH/Jord- och bergmekanik

    Author : Caesar Kardan; [2015]
    Keywords : CPT; CPTU; cone penetrometer; cone resistance; friction sleeve; pore pressure; undrained shear strength; conrad; CPT; CPTU; sond; spetsmotstånd; mantelfriktion; portryck; odränerade skjuvhållfasthet; conrad;

    Abstract : CPTU is one of the most sophisticated geotechnical investigation methods. However, there is a large amount of uncertainties related to this method. The uncertainties depend on different types of factors, for instance lack of accuracy in performance and equipment. READ MORE

  4. 28. Investigation

    University essay from Lunds universitet/Geoteknik

    Author : Erik Månsson; [2014]
    Keywords : Technology and Engineering;

    Abstract : In mining for extraction of metals residues are often produced. A frequently produced residue is tailings, which potentially contains high amount of metals, soluble salts and acids. Therefore, it is often necessary to deposit, the tailings in stable impoundments, namely tailings dams, if not all tailings produced is used as backfill in mines. READ MORE

  5. 29. Shear Resistance Degradation of Lime –Cement Stabilized Soil During Cyclic Loading

    University essay from KTH/Jord- och bergmekanik

    Author : Alex Gezahegn Gebretsadik; [2014]
    Keywords : undrained cyclic triaxial test; lime-cement stabilized column; shear resistance; shear strain; degradation index; degradation parameter; pore pressure;

    Abstract : This thesis presents the results of a series of undrained cyclic triaxial tests carried out on four lime-cement stabilized specimens and clay specimen. The shear resistance degradation rate of lime-cement column subjected to cyclic loading simulated from heavy truck was investigated based on stress-controlled test. READ MORE

  6. 30. Rostfärgat slam i dränagesystem vid vattenkraftsanläggningar : orsaker och åtgärder

    University essay from SLU/Dept. of Energy and Technology

    Author : Anders Hamrén; [2013]
    Keywords : vattenkraft; dammar; järnbakterier; flödesmätning; dränagesystem;

    Abstract : From embankment dams is something that has long been noticed and given rise to different questions. The most serious question is if the sludge is a result of inner erosion through the dam, and thus consists of material transported from the dam. READ MORE
