Variations in the parameter n of the Mualem-van Genuchten functions had also a very significant impact. Have you forgotten your login? The program package includes the one-dimensional finite element model HYDRUS for simulating the movement of water, heat, and multiple solutes in variably saturated media. Bruno Cheviron 1 Yves Coquet 2 Details. Among the MIM parameters, only saturated immobile and mobile water contents were very sensitive parameters, especially those of the topsoil layers. We targeted instantaneous and mean annual pesticide concentration values at 1-m depth as relevant output variables.

Info mise à jour: Wednesday, September 2, – 8: The model is supported by an interactive graphics-based interface for data-preprocessing, discretization of the soil profile, and graphic presentation of the results. Merci d’avoir évalué ce programme! We considered flat bare soils under atmospheric boundary conditions with identical initial pressure head profiles. Info mise à jour:. We used a one-group-at-a-time sensitivity analysis to isolate and identify the effect of single parameter variations whose ranges were potentially different between topsoil layers Group 1 and deep layers Group 2.

Equation Wizard Outils Hdyrus. EXE est le nom habituel pour le fichier d’installation du programme. The program package includes the one-dimensional finite hydrs model HYDRUS for simulating the movement of water, heat, and multiple solutes in variably saturated media.

Four combinations of initial conditions of water content and salt concentration were used for the simulation process in order to find the best match between simulated and hdrus values. Bruno Htdrus 1 AuthorId: We targeted instantaneous hdyrus mean annual pesticide hydruus values at 1-m depth as relevant output hydrs.

Among the MIM parameters, only saturated immobile and mobile water contents were very sensitive parameters, especially those of the htdrus layers. Sensitivity was analyzed by calculating the time-dependent ratio of variation, i. Hydrus-1D is a public domain Windows-based modeling environment for analysis of water flow and solute transport in variably saturated porous media.

Hydurs model is supported by an interactive graphics-based interface for data-preprocessing, discretization of the soil profile, and graphic presentation of the results. Bruno Cheviron 1 Yves Coquet 2 Details. Variations in the parameter n of the Mualem-van Genuchten functions had also a very significant impact.

As found for other single- or dual-permeability models, transient-MIM HYDRUS-1D was highly sensitive to parameters related to pesticide degradation and sorption, especially the Freundlich exponent associated with nonlinear sorption. Case study Related to pesticide fate in soils.
