Analysis of the filter stability of soils after Cistin/Ziems.

Analysis of filter stability of soils after Cistin/Ziems and suffosion safety after Kenney/Lau and Burenkova.
Capabilities:
- Manual system data input or data import from the GGU-SIEVE program (determination and presentation of grain size distribution curves, Version 14 and upwards)
- Consideration of soil grain shape compliant with DB guideline 836 (module 836.4602A01: Tiefenentwässerungen, Nachweise der Filterstabilität von Filtern/Dräns (Deep drainage, analysis of the filter stability of filters/drains), 1st revision, 01 October 2008)
- Visualisation of the allowable interval ratio between the filter and the protected soil as a function of their uniformity coefficients in the Cistin/Ziems diagram
- Input data and analysis results displayed in a legend
- Examples from DB guideline 836 and Merkblatt Anwendung von Kornfiltern an Wasserstraßen (MAK) published by Bundesanstalt für Wasserbau (BAW) in Karlsruhe, 1989
- User-defined design of output sheet
