      In this paper, we visually analyze spatio-temporal patterns of different hydrologic parameters relevant for flooding. On the basis of data from climate simulations with a high resolution regional atmosphere model, several ...
    • MO2GEO - a Small Tool for Registration and Visualization of Geological Data 

      Schimpf, L.; Gossel, W. (The Eurographics Association, 2013)
      Geological data have to be registered according to country-specific standards and visualized in 3D tools. Both topics are addressed by the tool MO2GEO, which is flexible enough to allow the insertion of common national ...
    • 3D Visualization of Atmospheric Data for Analytical Approaches 

      Helbig, C.; Rink, K.; Bauer, H.-S.; Wulfmeyer, V.; Frank, M.; Kolditz, O. (The Eurographics Association, 2013)
      In the future, climate change will strongly influence our environment and living conditions. Climate simulations that evaluate these changes produce huge data sets. The combination of various variables of the model with ...
    • Rendering Technique of Multi-layered Domain Boundaries and its Application to Fluid Flow in Porous Media Visualizations 

      Naumov, D.; Bilke, L.; Kolditz, O. (The Eurographics Association, 2013)
      Current visualization techniques for computational fluid dynamics applications are sofisticated and work well in simple geometries. For complex geometries like pore spaces, multiple domain boundaries are obstructing the ...
    • Visualizing Saline Intrusion in a Three-Dimensional, Heterogeneous, Coastal Aquifer 

      Walther, M.; Bilke, L.; Delfs, J.-O.; Graf, T.; Grundmann, J.; Kolditz, O.; Liedl, R. (The Eurographics Association, 2013)
      We visualize remediation scenarios for a coastal aquifer in Oman, where the natural fresh-saltwater interface is negatively affected by groundwater pumping for irrigation. The 3D aquifer is characterized by strong ...
    • Using K-Means Clustering for a Spatial Analysis of Multivariate and Time-Varying Microclimate Data 

      Häb, Kathrin; Middel, Ariane; Hagen, Hans (The Eurographics Association, 2013)
