Sammanfattning
This thesis identifies and evaluates existing methodological approaches to the
initial stages of the planning phase of MAR, including the localisation of suitable sites.
The aim is to compare methodologies for site suitability evaluation in Swedish
conditions. Hydrogeological, geological, and hydrological parameters, which are expected
to have a large influence on the site suitability for MAR are identified. This is
achieved by conducting a literature study of guidelines, scientific articles and case
study reports in the field of MAR site suitability analysis. The main difference in the
application lies with the parameters recommended for the evaluation, this is mainly
due to the geological differences in Sweden compared to the rest of the world.
Furthermore, based on the literature analysis, an approach is selected, adjusted, and
implemented in a case study on a region in Sweden to evaluate its suitability in
Swedish conditions.
The literature review has shown that site suitability evaluation is a crucial part
of the planning phase for MAR. The approach of conducting a GIS-MCDA for site
suitability evaluation was assessed as possibly suitable for Swedish conditions. To
evaluate this, a GIS-MCDA was implemented to the case study with the purpose of
identifying suitable areas for MAR. For validation of the results, the outcome of the
GIS-MCDA was compared previously identified sites possibly suitable for MAR by
Stockholm Vatten AB et al. (1996). As the same areas previously identified as
suitable were suggested also in this analysis, the GIS-MCDA was assessed as successful.
In conclusion, the methodology found in the literature is assessed as a promising
approach to be applied in Swedish conditions.
