1. Morphometric and Landscape Feature Analysis with Artificial Neural Networks and SRTM data : Applications in Humid and Arid Environments
Sammanfattning : This thesis presents a semi-automatic method to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as an unsupervised Artificial Neural Network algorithm in two completely different environments: 1) the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) as a complex mountainous humid area and 2) Lut Desert, Iran, a hyper arid region characterized by repetition of wind-eroded features. In 2003, the National Aeronautics and Space Administration (NASA) released the SRTM/ SIR-C band data with 3 arc seconds (approx. LÄS MER
2. Artificial neural networks : applications in morphometric and landscape features analysis
Sammanfattning : In this thesis a semi-automatic method is developed to analyze morphometric features and landscape elements based on Self Organizing Map (SOM) as a unsupervised Artificial Neural Network algorithm. Analysis and parameterization of topography into simple and homogenous land elements (landform) can play an important role as basic information in planning processes and environmental modeling.

3. Form and Function of Coastal Areas
Sammanfattning : Coastal waters have high biological productivity and provide goods and services with a high monetary value. Coasts are used by many different stakeholders and are often densely populated. LÄS MER
4. On the role of morphometry in coastal ecosystem modelling and management
Sammanfattning : Many signs show that the Baltic Sea is increasingly eutrophicated. Primary production hasincreased significantly resulting in gradually decreasing deep water oxygen concentrationsduring the twentieth century. In the coastal zone, problems are often manifested as oxygendepletion resulting in extinction of macrobenthic fauna. LÄS MER
5. Landslide scars in the Kenyan highlands : Physical and chemical topsoil changes and landslide susceptibility assessment under tropical conditions
Sammanfattning : Farmers living in the Kenyan highlands are exposed to the risk of being affected by landslides and they are vulnerable because of lack of resources. Vulnerability can be reduced by increasing knowledge and awareness of the risk. This thesis aims to increase knowledge of landslide-related problems. LÄS MER
