Simulation of municipal landfill leachate movement in soil by HYDRUS-1D model
Different numerical and analytical models are presently available that provide the tools to predict pollutant and water transfer processes between the soil surface and the groundwater level. Among the existing models, the Hydrus-1D model has been used for years in the prediction of water and pollutants transfer in the unsaturated zone. The main purpose of this paper was to model the movement of...
متن کاملEffect of Incorporation of Wheat Residues to Soil on Physiological Traits and Canned Yield of Sweet Corn under Water Stress
A two-year field experiment (2015–2016) was conducted as a split plot design with four replications at School of Agriculture, Shiraz University, Iran to investigate the influence of water stress (supplying 50, 70, and 100% of water requirement) and wheat residue rates (0, 25, and 50%) incorporated with soil on physiological traits and canned yield of sweet corn (Zea mays L. V. Saccharata). Net ...
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...
متن کاملsimulation 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 کاملSensitivity Analysis of Hydraulic Parameters in the Simulation of Unsaturated Soil Water Dynamics
Soil water content is one of the most important parameters for estimating irrigation frequency and providing the plant’s water requirement. Since measurement of soil water content is both expensive and time consuming, water movement models are used to estimate these values. In this study, LEACHW model was used to estimate soil water content for two “dry” (20-29 Aug) and “wet” (1-6 Jul) periods ...
