Aboufayed Method for Measuring Infiltration Rates and Identification of Profile Features Influencing Them

Abstract

Aboufayed method is a simple procedure for measuring infiltration rate using single ring infiltrometers consisting of 50 cm long stainless steel tubes of 11 cm diameter. Water was supplied to the infiltrometer rings from glass reservoir bottles (approximate volume - 1100 cm3) to which clear plastic rulers had been attached. The bottles were fitted with narrow-bore delivery tubes of a length that ensured the establishing of a constant head inside the infiltrometer rings. The developed procedure for measuring infiltration is simple and practical and permit measurement of the infiltration rate at different depths simultaneously. It could be carried out under light rainfall events because the infiltrometer ring is covered by the reservoir bottle and therefore not exposed to the atmosphere. It was found to be adaptable for use under different land - use in different geographic regions.
