research

  A list of research projects i have worked for at Univ. of Kassel since 1995:

• Using Agrometeorological Network Data for Improved Semi-Arid and Arid Agrosystem Management
  BMFT-Project University of Rio Grande do Sul - Brazil / Institute of Soils and Water - Bet Dagan -Israel / FG Kulturtechnik GhKassel
  (Dr. Matthias Langensiepen)
  My tasks were
  a) the design and execution of a field experiment for the monitoring of soil water dynamics using tensiometry, gravimetry and the gypsum block method.
  b) determination of soil physical and hydraulic properties.
  c) assistance with measurement of plant geometry (angular distribution of leaf area), sap flow in plants using the heat-pulse method and measurement of angular light response of stomatal conductance by porometry
  
  
• Pilot project Bleicherode, sub projects
  Direktbegrünung von anhydritischen Steinsalzhalden unter Verwendung von organischen Abfällen (Dr. Michael Lücke)
  Recultivation of saline waste dumps with thin layers consisting of soil material, lignite ashes and organic waste (Dr. Günther Podlacha)
  My tasks were the management and analysis of weather data from several automatic stations, modeling of evapotranspiration and soil water dynamics, assistance with lysimeter data analysis.
  
  
• Auswirkungen der Werraversalzung auf die Baggerseen des Naturschutzgebietes Freudenthal bei Witzenhausen (Dr. Wilko Schweers)
  My tasks were: assistance with measurement of hydrological and water quality parameters, assistance with modeling of actual evapotranspiration.
  
  
• Synthesis and consistency-check of complex modular-hierarchical ecosystem models (Dr. Joachim Benz)
  As a member of the ECOBAS group from 1997 to 2003, my tasks were: conceptual work, development of several generations of model documentation and simulation software, development of a model documentation standard, model analysis, organisation of workshops, software support, international meetings.
  
  
• Register of Ecological Models (Dr. Joachim Benz)
  My tasks were: development of WWW-information system and database with the REM team, classification and description of models, international correspondence.
