  1. 1. Automated performance monitoring of concrete dams

    University dissertation from Avd. för Teknisk Geologi

    Author : Christian Bernstone; Lunds universitet.; Lund University.; [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.

  2. 2. Influence of Sea Surface Temperature on Rainfall and Runof in Northeastern South America: Analysis and Modeling

    University dissertation from Department of Water Resources Engineering, Lund Institute of Technology, Lund University

    Author : Cintia Bertacchi Uvo; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kartografi; marklära; geomorfologi; Fysisk geografi; climatology; pedology; cartography; Physical geography; geomorphology; sea surface temperature; rainfall-runoff; Amazonia; precipitation; Northeast Brazil; klimatologi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi;

    Abstract : This work represents an amalgam of a group of studies with the purpose of understanding the influence of the Pacific and Atlantic sea surface temperature on precipitation and river discharge in Northeastern South America. Sea surface temperature is a good representative of phenomena such as ENSO that, in turn, cause worldwide climate variability. READ MORE

  3. 3. Groundwater occurrence and risk of pollution in a mountain watershed of Nicaragua

    University dissertation from Engineering Geology, Lund University

    Author : Alfredo Mendoza; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; electrical resistivity; surface water; springs; Nicaragua; Hydrogeology; groundwater; teknisk geografi; geographical and geological engineering; Hydrogeologi;

    Abstract : Hydrogeological and geophysical methods were applied in the Río Artiguas watershed, a mountain basin located in central Nicaragua. This area is under environmental stress from anthropogenic activities like gold mining using mercury and waste disposal into the streams. READ MORE

  4. 4. Surface Wave Testing of Pavements

    University dissertation from Nils Ryden, Department of Engineering Gelogy, Lund Institute of Technology, Lund University, BOX 118, 22100 Lund

    Author : Nils Rydén; Lunds universitet.; Lund University.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Hydrogeology; inversion; guided waves; road; pavement; Surface waves; non-destructive testing;

    Abstract : A novel approach for surface wave testing of pavements is presented. It is a non-destructive testing (NDT) technique that can be used to obtain the thickness and stiffness properties of the different layers in a pavement. READ MORE

  5. 5. 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; Lunds universitet.; Lund University.; [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
