   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

   Sammanfattning : Analysis of digital elevation models (DEMs) by means of geomorphometry provides means of recognising fractures and characterising the morphotectonics of an area in a quantitative way. The objective of the thesis is to develop numerical methods and a consistent GIS methodology for tectonic geomorphology and apply it to test sites. LÄS MER

3. 2. Geochemical Landscape Analysis for the Risk Assessment of Acid Mine Drainage in a Wetland Environment

   Författare :Andrea Szucs; Ulf Qvarfort; Richard Wanty; Uppsala universitet; []
   Nyckelord :Earth sciences; acid mine drainage; environmental geochemistry; landscape; risk assessment; stream; wetland; Geovetenskap;

   Sammanfattning : Attenuation of acid mine drainage (AMD) metals originating from abandoned mines and waste rock dumps is investigated in this thesis at Slättberg in central Sweden, where acid mine leachate has been discharging for over 70 years into the receiving wetland stream and mire. Risk assessment of AMD and related polluted lands requires a holistic approach that is able to study the complexity of pollution emissions and impacted landscapes. LÄS MER
