Partial Abstract: Present Corps of Engineer (CE) filter criterion (EM 1110-2-1901, Appendix D) dates from the early 1950's, and some uncertainty exists as to the applicability and adequacy of this criterion under various conditions. Laboratory filter tests were conducted on uniform and poorly-graded cohesionless base materials protected by various filters, and internal stability tests were conducted on various graded filter materials. Based upon the limited tests conducted, the following changes to CE filter criterion are proposed.
