  1. 1. Stochastic analysis of fluid flow and tracer pathways in crystalline fracture networks

    University dissertation from Stockholm : KTH

    Author : Andrew Frampton; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Groundwater; Fractured media; Transport; Retention; Macrodispersion; Lagrangian formulation; Stochastic modelling; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi; TECHNOLOGY Other technology Environmental engineering; TEKNIKVETENSKAP Övriga teknikvetenskaper Miljöteknik;

    Abstract : Understanding groundwater flow systems and how these control transport is an essential part in assessing the suitability of subsurface environments as hosts for storage of toxic waste. Therefore it is important to be able to integrate knowledge obtained from field characterisation of the subsurface with methods which can be used to evaluate and predict possible impact on surrounding environments.

  2. 2. The influence of clouds on Earth's radiation budget in global climate models

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Johannes Karlsson; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Meteorology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Meteorologi; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Oceanography; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Oceanografi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Considering the high sensitivity of climate to changes in cloudiness, the way clouds might change in a perturbed climate is important for the total temperature response. In fact, the cloud feedback has been identified as the main uncertainty in future projections, as simulated by global climate models. READ MORE

  3. 3. Asymptotic methods applied to some oceanography-related problems

    University dissertation from Stockholm : Department of Meteorology, Stockholm University

    Author : Moundheur Zarroug; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Asymptotic analysis; internal waves; geophysical fluid dynamics; thermal oscillator; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Oceanography; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Oceanografi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : In this thesis a number of issues related to oceanographic problems have been dealt with on the basis of applying asymptotic methods.  The first study focused on the tidal generation of internal waves, a process which is quantifed by the conversion rates. These have traditionally been calculated by using the WKB approximation. READ MORE

    Abstract : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. READ MORE
