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

   Author : Semere Solomon; KTH; []
   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

4. 2. Terrain Modelling with GIS for Tectonic Geomorphology : Numerical Methods and Applications

   Author : Gyözö Jordan; Ulf Qvarfort; Tsehaie Woldai; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; digital elevation model; digital terrain modelling; GIS; morphometry; tectonic geomorphology; Miljöteknik; Environmental engineering; Miljöteknik;

   Abstract : 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. READ MORE

5. 3. Development of a Detailed Geomorphological Mapping System and GIS Geodatabase in Sweden

   Author : Marcus Gustavsson; Else Kolstrup; Harry Seijmonsbergen; Ian S. Evans; Uppsala universitet; []
   Keywords : Physical geography and sedimentology; Geomorphology; Geomorphological map; GIS; Sweden; Naturgeografi och sedimentologi;

   Abstract : This thesis presents a method for detailed landscape presentation. The method incorporates both fieldwork-based comprehensive geomorphological description and digital data handling and thus contributes in filling the gap between traditional geomorphological mapping and modern geomorphological studies performed in Geographic Information Systems (GIS).

6. 4. Spatial Variation in Near-Ground Radiation and Low Temperature - Interactions with Forest Vegetation

   Author : Kristina Blennow; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; light interception; hemispherical photograph; growth; forest fragmentation; fluorescence; cold-induced photoinhibition; GIS; view factor; radiative cooling; frost protection; agro-climatic mapping; forest clear-cut; local climate; Microclimate; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

   Abstract : Low temperature has a large impact on the survival and distribution of plants. Interactive effects with high irradiance lead to cold-induced photoinhibition, which may impact on the establishment and growth of tree seedlings. READ MORE

7. 5. Cenozoic landscape evolution in northern Sweden : Geomorphological interpretation within a GIS-framework

   Author : Karin Ebert; Clas Hättestrand; Paul Bishop; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Long-term geomorphology; northern Sweden; base-level surface; inselbergs; digital elevation models; field observations; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

   Abstract : The large-scale bedrock landscape in northern Sweden has a complex evolution history of planation, uplift, transgression, burial, weathering, and erosion. The aim of this thesis is to examine the long-term development of the area. Terms for base-level surfaces in the area are defined. READ MORE
