Preferential Flow of Water in a Structured Soils AKTION Österreich - Tschechische Republik
Abstract
Using the simulation model HYDRUS water movement from loamy to clayey soil, which is affected by preferential flow, will be simulated. In various depths moisture content and suction head will be measured by sensors. To complete the simulation with HYDRUS inverse modelling will be employed to estimate the unknown parameters and boundary conditions. The feasibility of detecting and quantifying the preferential flux at different depths during rapid percolation events will be explored. Further, the results of this research will make it possible to improve the estimate of water balance and water pollution risk in similar soils, especially in regions affected by intensive agriculture or mining.
