Analysis of transient groundwater flow using the finite-element method, based on a groundwater system modelled using GGU-2D-SSFLOW


  • Adoption of the steady-state GW data, soil colours, etc. from GGU-2D-SSFLOW
  • Consideration of phreatic lines and unsaturated zones
  • Graphic-oriented input and modification of time boundary conditions, e.g. polygon courses for time-data pairs, potentials or sources
  • Graphic-oriented input and modification of fixed boundary conditions, e.g. potentials, point, line and diffuse sources
  • Import and export ASCII data
  • Permeability function = f(time)
  • Standard values for nw = f(u) for soils

Evaluation and graphical visualisation of analysis results using the supplementary program GGU-PLGW

  • Coloured visualisation of GW potentials in the system cross-section
  • Determination and visualisation of potentials, velocities and gradients as normal, colour-filled or 3D contours
  • Visualisation of discharges in a circle diagram or between two points in time
  • Calculation of a groundwater-filled volume
  • Determination and (coloured) visualisation of groundwater thickness, groundwatersurface distance and confined regions
  • Analysis and visualisation of flow lines with distance and time increments
  • Visualisation of potentials as hydrographs for individual system nodes
  • Time-correlated visualisation of potentials, seepage velocities and gradients in userdefinable sections
  • Visualisation of phreatic lines
  • Visualisation of differential contours
  • Animated visualisation of potential history over time
  • 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
