Analysis of material transport in non cohesive soils using the following methods: 

• Filter stability after Cistin/Ziems 
• Suffusion safety after Kenney/Lau 
• Suffision safety after Burenkova 
• Interface erosion at layer boundaries complient with TAW  

described in Code of Practice “Material Transport in the Soil“ (German: “Merkblatt Materialtransport im Boden (MMB)“, published by Bundesanstalt für Wasserbau (BAW) in Karlsruhe, 2013)  

and 

• filter stability of geotextile filters; 

described in DWA-M511 Code of Practice “Filters using geosynthetics”, (German: “Filtern mit Geokunststoffen“, 2015).

Capabilities:

• Manual system data input or data import from the computer program GGU-SIEVE  (determination and presentation of grain size distribution curves, Version 14 and upwards) 
• For interface erosion at layer boundaries, permeabilities for common soils can be selected from an expandable database 
• 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) 
• Visualization of the allowable interval ratio between the filter and the soil to be protected as a function of their uniformity coefficient in the Cistin/Ziems diagram 
• Design of geotextiles and search for optimal product following the analysis of the filter stability of geotextile filters compliant with the DWA-M511 Code of practice 
• Visualization of suffosion saftey after Kenney/Lau, very convenient as a data import from the computer program GGU-SIEVE possible 
• Visualization of suffosion saftey after Burenkova 
• Visualization of interface erosion at layer boundaries in a model compliant with TAW  
• 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  
• User-defined design of output sheet 
• Print or copy screen sections, e.g. for transfer to a word processor 
• Integrated Mini-CAD system for additional annotation of graphics
