Abstract: Geotextile filters are rapidly replacing graded granular filters in dams, landfills, edge drains, and retaining walls. The design of these filters requires morphological information about the geotextile. Digital image processing is a tool which can be utilized to obtain such information effectively. In this paper typical results obtained for a nonwoven geotextile by digital image processing are presented. The advantages and disadvantages of the use of digital image processing for geotextile study are also discussed.
