Table D.1
Shape and dimensions of geotextile tubes
for various degrees of filling. The shaded
area represents the most common degree of
filling, based on the cross-sectional area of
the geotextile tube.

radius of the quadrants for both sides of the straight basis
of the geotextile tube.

TUBE WIDTH AND HEIGHT
If a specific degree of filling is chosen, then the width and the height of the geotextile
tube can be expressed in terms of the radius of the notional circle for 100% degree
of filling.
