In order to investigate the use of geotextile bags for dewatering slurries, an analytical model for a fluid draining from a hanging geotextile bag is derived and presented in dimensionless form. A data analysis procedure is proposed. Experimental results using water as the fluid with specially constructed geotextile bags are compared with the model and show excellent agreement. The model is applied to data for slurry-filled bags and used to determine the overall permittivity of a hanging bag dewatering system and the fraction of the bag’s volume drained as fluid.
