The interactive influence of furrow surface seal formation and surge irrigation (intermittent flow) on furrow infiltration into a Portneuf silt loam soil was measured with a recirculating infiltrometer. When the formation of a surface seal was prevented by a layer of cheesecloth laid on the furrow perimeter, flow interruption increased furrow bed bulk density by 100 kg/m 3 and decreased infiltr...

The soil sorptivity, S, and saturated hydraulic conductivity, Ks, can be estimated from the inverse analysis of a cumulative infiltration curve using quasi-exact implicit (QEI) formulation or its corresponding 4-Terms (4T) approximation. Although these models consider as homogeneous media, there is no information about how heterogeneous profiles affect inferred properties. This work analyzes in...
