simulation of soil moisture under a line ssource in a heavy soil texture with hydrus-2d
as irrigation system installation is expensive and time consuming, it would be better to have an estimate of the water content provided by the system in the active root zone before designing an irrigation system. in this study, hydrus-2d performance was assessed under a tape irrigating in-situ with a heavy textured and relatively heterogeneous soil in rasht region. three different flows i.e. 2....
متن کاملthe study of nitrate dispersivity in sandy soil using hydrus-1d model
the increasing use of nitrogen fertilizers due to high dynamics of nitrate in the soil would be a serious threat to groundwater, and therefore, to thuman health. this study is aimed to investigate the disperdivity values of nitrate in the coarse, medium and fine sandy soils in the short travel distance of 20, 40 and 80 cm in vitro using the hydrus-1d model. for this purpose, pure potassium nitr...
متن کاملParameter estimation of soil hydraulic and thermal property functions for unsaturated porous media using the HYDRUS-2D code
Knowledge of soil hydraulic and thermal properties is essential for studies involving the combined effects of soil temperature and water input on water flow and redistribution processes under field conditions. The objective of this study was to estimate the parameters characterizing these properties from a transient water flow and heat transport field experiment. Real-time sensors built by the ...
متن کاملComparison of Pesticide Transport Processes in Three Tile-Drained Field Soils Using HYDRUS-2D
The purpose of this study was to assess the transport of the herbicide bentazone [3-(1-methylethyl)-1H-2,1,3-benzothiadiazin-4(3H)one 2,2-dioxide] in three contrasting tile-drained cultivated field soils subject to otherwise similar experimental conditions. Observed drain discharge rates and chemical concentrations in the drainage water reflected the different transport processes at the three s...
متن کاملAnalysis of 2,4-D residues in soil profile using HYDRUS-1D model
ABSTRACT- Despite the benefits of herbicides, their persistence in soil can harm other plants in next rotations and contaminate ground water. The main purpose of this research is to simulate 2,4-dichlorophenoxyaceticacid(2,4-D) movement in silty clay loam soil using HYDRUS-1D model in a corn root zone. The maximum contaminant level goal, MCLG, of 2,4-D in water resources is 10 ppb. The 3.5 kg a...
