Precipitation infiltration

Analysis of systems for the infiltration of precipitation run-off according to the DWA-A 138 standard (Deutsche Vereinigung für Wasserwirtschaft, Abfall und Abwasser e.V.; Planung, Bau und Betrieb von Anlagen zur Versickerung von Niederschlagswasser, April 2005).

The following systems are analysed:

  • Surface infiltration
  • Swale infiltration
  • Pipe infiltration
  • French drain infiltration
  • Shaft infiltration
  • Certain combinations of the above systems

Capabilities:

  • Analysis using rainfall intensity tables from the KOSTRA atlas
  • Draft design also using Reinhold's rainfall series’
  • Import of the rainfall intensity data determined using the KOSTRA atlas via a file or via the Windows clipboard
  • Combination of infiltration systems compliant with DWA-A 138 (e.g. swale-pipe infiltration)
  • Combination of infiltration systems compliant with DWA-A 138 with paved areas (e.g. paving with swale)
  • Analysis of infiltration systems for a variety of frequencies (recurrence intervals)
  • Calculation of draining times for given infiltration types
  • User-defined output sheet
  • Print or copy screen sections, e.g. for transfer to a word processor
  • Integrated Mini-CAD system for additional annotation of graphics

System requirements

GGU-Software runs on PCs with the following specifications:

  • Pentium III or higher processor
  • Microsoft Windows® 7, 8, 8.1and10 compatible
  • 500 MB free hard disk space
  • DVD-ROM drive or internet connection (for installation)
  • USB Interface 2.0 or higher (for licence dongle)
