  1. 1. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

    University dissertation from Stockholm : Byggvetenskap

    Author : Semere Solomon; KTH.; [2003]
    Keywords : Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

    Abstract : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. READ MORE

  2. 2. Uncertainty Modelling in Hydrological Applications - Error Propagation Properties of Random Linear Systems

    University dissertation from Department of Water Resources Engineering, Lund University, Box 118, S-221 00 Lund, Sweden

    Author : Jan Agerholm Høybye; Lunds universitet.; Lund University.; [1998]
    Keywords : Hydrogeology; geographical and geological engineering; floods; water quality; prediction uncertainty; differential equations; Stochastic hydrology; random functions; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Geovetenskap; Earth sciences;

    Abstract : In hydrological models for water resources management and planning, the model output or design quantities are functions of the input data and a number of parameters that are essentially stochastic processes or random variables. The task of uncertainty analysis is to estimate the uncertainty characteristics of the model output in terms of the uncertainties in the input, model parameters and initial conditions. READ MORE

  3. 3. Generation of Leachate and the Flow Regime in Landfills

    University dissertation from Dept. Water Resources Engineering, Lund University, Box 118, 22100 Lund, Sweden

    Author : David Bendz; Lunds universitet.; Lund University.; [1998]
    Keywords : Hydrogeologi; teknisk geologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi; Geovetenskap; Earth sciences;

    Abstract : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. READ MORE

  4. 4. Automated performance monitoring of concrete dams

    University dissertation from Avd. för Teknisk Geologi

    Author : Christian Bernstone; Lunds universitet.; Lund University.; [2006]
    Keywords : teknisk geologi; Hydrogeologi; 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; Geovetenskap; Earth sciences;

    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.

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

    University dissertation from Dept of Water Resources Eng., Box 118, S-221 00 Lund, Sweden

    Author : Cintia Bertacchi Uvo; Lunds universitet.; Lund University.; [1998]
    Keywords : marklära; kartografi; 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; Geovetenskap; Earth sciences;

    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
