Analysis of transient groundwater flow using the finite-element-method based on a three-dimensional groundwater system analysed using GGU-3D-SSFLOW


  • Consideration of seepage lines and unsaturated zones
  • Graphics-oriented input and editing of time boundary conditions, e.g.polygon courses for time-measured value data pairs, potentials or sources
  • Graphics-oriented input and editing of fixed boundary conditions, e.g. potentials, point, linear and diffuse sources
  • Coloured visualisation of the groundwater potentials in section
  • Visualisation of potentials as hydrographs for individual system nodes
  • Time-oriented visualisation of velocities, discharges or potentials, e.g. as normal, colour-filled or 3D contours
  • Animated screen visualisation of potentials with time
  • Visualisation of vertical sections for individual planes/layers
  • Coloured result visualisation in the 3D model, e.g. potential lines and surfaces, flow lines
  • User-designed output sheet
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics
