1. 1. Dynamic Warning Signals and Time Lag Analysis for Seepage Prediction in Hydropower Dams : A Case Study of a Swedish Hydropower Plant

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

   Författare :Lovisa Olsson; Julia Hellström; [2023]
   Nyckelord :hydropower; dam safety; dam monitoring; seepage; prediction models; data-driven methods; artificial intelligence; AI;  linear regression; Support Vector Regression; SVR; Long Short-Term Memory; LSTM;

   Sammanfattning : Hydropower is an important energy source since it is fossil-free, renewable, and controllable. Characteristics that become especially important as the reliance on intermittent energy sources increases. However, the dams for the hydropower plants are also associated with large risks as a dam failure could have fatal consequences. LÄS MER

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

   Master-uppsats, KTH/Betongbyggnad

   Författare :Jarl Jensen; Markus Leijström; [2022]
   Nyckelord :;

   Sammanfattning : 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. LÄS MER

4. 3. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

   Författare :Eduardo Garcia Cañas; [2022]
   Nyckelord :HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

   Sammanfattning : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. LÄS MER

5. 4. Geomechanical testing of non-hardening grout : for determination of flowability and strength properties

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Geoteknologi

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

   Sammanfattning : 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. LÄS MER

7. 5. Analysis of seepage, contaminant transport, compaction and safety of the Zhaoli ditch dam, a tailing reservoir : A modeling study of a tailing reservoir with GeoStudio

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Veronika Wei Wang; [2021]
   Nyckelord :upstream method; Geostudio; tailings reservoir; tailings dam; dam; seepage; contaminant transport; compaction; stability; damm; föroreningstransport; vattenläckage; stabilitet; säkerhet;

   Sammanfattning : Inthe mining industry people remove rock from the ground to obtain a metal ore. Afterprocessing , the uneconomic fraction called tailings is deposited as a slurry in large reservoirs . LÄS MER
