  1. 1. Internal Erosion Phenomena in Embankment Dams Throughflow and internal erosion mechanisms

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Farzad Ferdos; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal erosion modelling in porous material; Constitutive law of erosion for closure of continuum-mechanics-based balance equations for numerical modelling; High Reynolds-number turbulent flow; Flow laws; Coarse rockfill material throughflow; Computational Fluid Dynamics.; Civil and Architectural Engineering; Byggvetenskap;

    Abstract :  In this study, two major internal erosion initiation processes, suffusion and concentrated leak mechanisms, which lead to both defect formation in a dam’s body and its foundation and high throughflow in dams subjected to internal erosion were studied. This understanding has the potential to facilitate numerical modelling and expedite dam safety assessment studies. READ MORE

  2. 2. Tailings Dam Performance Modeling and Safety Analysis of a Tailings dam

    University dissertation from Luleå tekniska universitet

    Author : Roger Knutsson; Luleå tekniska universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Storage and management of mine waste are both needed in the mining industry. After mineral extraction of the ore, there are generally leftovers with insufficient economical value that need to be taken care of. The finest grained fractions are referred to as tailings. READ MORE

  3. 3. Resistivity investigation and monitoring for detection of internal erosion and anomalous seepage in embankment dams

    University dissertation from Engineering Geology, Lund University

    Author : Pontus Sjödahl; Lund University.; Lunds universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeologi; teknisk geologi; internal erosion; Hydrogeology; geographical and geological engineering; time-lapse inversion; inversion; monitoring; modelling; resistivity; detection; leakage; seepage; teknisk geografi; embankment dam;

    Abstract : Methods for monitoring seepage and detecting internal erosion are essential for the safety evaluation of embankment dams. Internal erosion is one of the major reasons for embankment dam failures, and there are several tenths of thousands of large embankment dams in the world. READ MORE

  4. 4. Sedimentological and Hydrological Investigation of Mosul Dam Reservoir

    University dissertation from Luleå tekniska universitet

    Author : Issa E Issa; Luleå tekniska universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-storage capacity curves; Area reduction method; Bathymetric survey; Losing storage capacity; Mosul dam; Reservoir bottom morphology; Reservoir sedimentation; Sediment trap efficiency; Useful life of dam; Geoteknik; Soil Mechanics;

    Abstract : Reservoir sedimentation is the main problem that directly affects the performance of dams due to the reduction in the storage capacity of their reservoirs. Monitoring the storage capacity of reservoirs is an important issue for the planners, designers and operators of the dams. READ MORE

  5. 5. Automated performance monitoring of concrete dams

    University dissertation from Avd. för Teknisk Geologi

    Author : Christian Bernstone; Lund University.; Lunds universitet.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeologi; teknisk geologi; geographical and geological engineering; Maintenance; Uplift pressure; Crack; Deformation; Image processing; Dams; Condition monitoring; Time-domain reflectometry; GPS; Image analysis; Concrete structures; teknisk geografi; Hydrogeology;

    Abstract : The Swedish hydropower industry operates a large number of power plants and dams geographically spread over the country. The level of safety of a specific dam is to a large extent determined during the design and construction phases that in the case of Swedish hydropower plants took place several decades ago. READ MORE
