“…It can be set to 0.6 (Vandervaere et al, 2000b). From comparison with experimental data, Smettem et al (1994) showed that an appropriate value for g is a constant equal to 0.75. All the infiltrometer tests were analysed by the socalled 'Differentiated Linearisation' method (Vandervaere et al, 1997) which was shown to be robust (Vandervaere et al, 2000a).…”

Abstract:Ponded infiltration experiment is a simple test used for in-situ determination of soil hydraulic properties, particularly saturated hydraulic conductivity and sorptivity. It is known that infiltration process in natural soils is strongly affected by presence of macropores, soil layering, initial and experimental conditions etc. As a result, infiltration record encompasses a complex of mutually compensating effects that are difficult to separate from each other. Determination of sorptivity and saturated hydraulic conductivity from such infiltration data is complicated. In the present study we use numerical simulation to examine the impact of selected experimental conditions and soil profile properties on the ponded infiltration experiment results, specifically in terms of the hydraulic conductivity and sorptivity evaluation. The effect of following factors was considered: depth of ponding, ring insertion depth, initial soil water content, presence of preferential pathways, hydraulic conductivity anisotropy, soil layering, surface layer retention capacity and hydraulic conductivity, and presence of soil pipes or stones under the infiltration ring. Results were compared with a large database of infiltration curves measured at the experimental site Liz (Bohemian Forest, Czech Republic). Reasonably good agreement between simulated and observed infiltration curves was achieved by combining several of factors tested. Moreover, the ring insertion effect was recognized as one of the major causes of uncertainty in the determination of soil hydraulic parameters.

“…Valiantzas (2010), proposed a two-parameter equation which is a specific solution that is approximately located at the middle of the domain of real soils defined by two ''limiting'' behaviour soils. Other expressions used to estimate the soil hydraulic parameters from the transient flow (Warrick and Lomen, 1976;Warrick and Broadbridge, 1992;Zhang, 1997;Smettem et al, 1994) have in common the two-term equation proposed by Philip (1957) for three-dimensional cumulative infiltration (I)…”

2Measurements of soil sorptivity (S 0 ) and hydraulic conductivity (K 0 ) are of paramount importance for 3 many soil-related studies involving disciplines such as agriculture, forestry and hydrology. In the last 4 two decades, the disc infiltrometer has become a very popular instrument for estimations of soil 5 hydraulic properties. The previous paper in this series presented a new design of disc infiltrometer 6 that directly estimates the transient flow of infiltration rate curves. The objective of this paper is to 7 present a simple procedure for estimating K 0 and S 0 from the linearization of the transient infiltration
