  2. 1. Hydrogeochemistry and spatial variability of arsenic and other trace elements in the Lower Katari Basin around Lake Titicaca, Bolivian Altiplano. : Impact on drinking water quality and groundwater management

    Author : Israel Quino Lima; Prosun Bhattacharya; Jerker Jarsjö; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arsenic; trace elements; multivariate analysis; spatial variability; hydrogeology; spatio-temporal variability; Lower Katari Basin; Bolivian Altiplano; alluvial sediments; Arsenik; spårelement; multivariat analys; rumslig variabilitet; hydrogeologi; spatio-temporär variation; Nedre Katari-bassängen; Bolivian Altiplano; alluviala sediment; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Arsenic (As) contamination in drinking water is a world-wide problem. Thenatural origin of As, its mobility and transport are of great interest in BolivianAltiplano (Lower Katari Basin: LKB and Sothern Poopó Basin: SPB) due topresence of mineral ore deposits, brines, hot springs and volcanic rocks.

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

    Author : Jan Agerholm Høybye; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; geographical and geological engineering; Hydrogeology; floods; water quality; prediction uncertainty; differential equations; Stochastic hydrology; random functions; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    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

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

    Author : David Bendz; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    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

  6. 4. Automated performance monitoring of concrete dams

    Author : Christian Bernstone; Teknisk geologi; []
    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.

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

    Author : Cintia Bertacchi Uvo; Avdelningen för Teknisk vattenresurslära; []
    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
