Three irrigation treatments were set up in northeast China to investigate soil water movement and root uptake of greenhouse tomatoes, the collected experimental data simulated by HYDRUS-2D. The computation partitioning evapotranspiration into evaporation crop transpiration was carried out with double-crop coefficient method. HYDRUS-2D model successfully movement, producing RMSE ranging from 0.0...

in this study, effect of slope on soil wetting pattern under surface drip irrigation and simulation with hydrus-2d model evaluated.the physical model made of plexiglas to size 83, 6 and 54 cm (length, width, height) filled with silty clay loam soil was used. to achieve the desired discharge, a small drip irrigation system created that includes a water tank with a fixed height (about 2 meters), ...

Knowledge of soil moisture dynamics in the unsaturated soil zone provides valuable information on the temporal and spatial variability of groundwater recharge. This is especially true for the Mediterranean region, where a substantial fraction of long-term groundwater recharge is expected to occur during high magnitude precipitation events of aboveaverage wet winters. To elucidate process unders...

Factors affecting preferential flow and transport in the vadose zone need to be investigated by experiments and simulations to protect groundwater against surface applied chemicals. The objectives of this study were to investigate the effects of several factors (soil structure, initial soil water content (SWC), and application rate) and their interactions on the extent of preferential flow and ...

In view of the potential soil leaching risk reuse fertilizer reclaimed from micro-flush sanitary wastewater, batch tests adsorption and degradation, column percolation test multi-stage box were adopted. The characteristics leachate after interaction between soil, as well changes attributes in system, analyzed. After obtaining correlation coefficients solute transport through above experiments, ...
