The paper deals with measurements of water infiltration carried out on a well-developed forest floor formed by needle-leaf litter Norway spruce. Three field methods (tension disk permeameter, single-ring infiltrometer and Guelph permeameter) were used to determine the soil hydraulic conductivity. results strongly influenced repellency at interface between O- A-horizons. This was severely repell...

Abstract The determination of soil hydraulic properties is important in several environmental sciences but may be expensive and time consuming. Therefore, during the last decades, a great effort has been made to develop relatively easy, robust, inexpensive methods for characterization. In this manuscript, we reviewed discussed different infiltrometer techniques light available experimental appl...

Developing correlations between various soil parameters are considered the major challenge to diminish time and cost associated with field measurements. Soil hydraulic and physical properties were extensively characterized using tension disc infiltrometer and soil sampling in a silty clay agricultural field in Kalaat El-Andalous, Tunisia. Tension disc infiltrometer experiments were conducted at...
