Pilot scale field tests were conducted to evaluate the performance of a geotube. The geotube was made of a woven geotextile which conformed to the minimum specifications provided by the U.S. Army Corps of Engineers. The results of a number of laboratory tests are presented: direct shear tests to determine the geotextile-sand interface friction angle, cyclic fluctuation tests to estimate the soil particle loss from the geotube, and long- and short-term environmental tests to evaluate the environmental effects of dissipated water from the geotube. Based on the present study it appears that the geotube is a fast, efficient, and environmentally sound dredging fill technique.
