Experimental study on the hydraulic performance of nonwoven geotextile as subsurface drain filter in a silty loam area

Synthetic geotextile envelope can be used as a replacement of sand filters for subsurface drainage pipes. However, clogging and blocking can occur if the filter does not match the soils properly. This paper presents a laboratory study on hydraulic performance of nonwoven geotextile as subsurface dra...
