Abstract

An experiment has been carried out in order to both measure the unsaturated hydraulic conductivity of a soil crust when it is developing and to characterize its macro- and microstructural evolution. Five stages of a structural crust developing in a loamy clay soil have been identified. Mercury intrusion experiments and micromorphological descriptions have provided information on the structural evolution of the crust at the microscale. Both the structural information given by the chord size distribution and the functional information obtained from the percolation threshold can be related to propose a new model of soil crusting
