| Abstract/Contents: | "Water repellent soil surface layers exhibit a complex flow and transport mechanism. Knowledge of the underlying principles is essential for instance to stimulate water availability for crops and to estimate leaching potentials of agrichemicals. The present study aimed to investigate water flow and solute transport processes in a water repellent sandy topsoil, and to introduce and apply a new modeling approach. Automated TDR measurements revealed that preferential pathways develop rapidly during severe rain storms, causing infiltrating water to be preferentially transported to the deeper subsoil. These preferred pathways recurred at the same sites during all rain events. The process of preferential flow and transport has been incorporated in the well-known SWAP models, and applied to field data of tracer transport through a water repellent sandy soil in the Netherlands. Flow concept and model structure have been outlined, and simulation results presented. Results indicated early arrival times of bromide tracer in the subsoil in the case where preferential flow is taken into account in the model. Several amelioration strategies to alleviate soil water repellency are highlighted, e.g. irrigation, clay additions, and application of surfactants." |
