GGU-2D-Transient - Geohydraulic Analysis Software

• 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
