Yves Coquet 2 AuthorId: A sensitivity analysis of the HYDRUS-1D model was performed based on scenarios that represented the fate of a nonvolatile pesticide in three soils. Hydrus-1D was a useful tool to predict the groundwater level and quality in the case of a direct recharge and in the absence of any information related to the soil layers except for the texture.

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.

Parameter sensitivities hardly varied among the three soils, but this could be due to their limited contrast. Simulations were conducted with Hydrus-1D code using measured precipitation data for the period and calculated evapotranspiration for both chosen profiles.

We targeted instantaneous and mean annual pesticide concentration values at 1-m depth as relevant output variables.

Bruno Cheviron 1 Yves Coquet 2 Details. The aquifer risk contamination is related to the natural conditions where it increased while facing climate change and temperature increase and decreased in the presence of a clay layer. Sensitivity was analyzed by calculating the time-dependent ratio of variation, i.

Variations in the parameter n of the Mualem-van Genuchten functions had also a very significant impact. Equation Wizard Outils Scientifiques. The success of the calibration of Hydrus-1D allowed the investigation of some scenarios in order to assess the contamination risk under different natural conditions. Wednesday, September 2, – 8: Four combinations of initial conditions of water content and salt concentration were used for the simulation process in order to find the best match hycrus simulated and measured values.

In this study, a methodology has been developed to evaluate groundwater contamination risk based on the unsaturated zone hydraulic properties. 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.

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. In semi-arid areas like the Kairouan region, salinization has become an increasing concern because of the constant irrigation with saline water and over use of groundwater resources, soils, and aquifers.

Hydrus-1D is a public domain Windows-based modeling environment for analysis of water flow and solute transport in variably saturated porous media. Among the MIM parameters, only saturated immobile and mobile water contents were very sensitive parameters, especially those of the topsoil layers. Citation Bruno Cheviron, Yves Coquet.

Sensitivity analysis of transient-MIM HYDRUS-1D: Case study Related to pesticide fate in soils

Reference values for most of the parameters were obtained from in situ or laboratory measurements. Case study Related hdrus pesticide fate in soils. The model is supported by an interactive graphics-based interface for data-preprocessing, discretization of the soil profile, and graphic presentation of the results.
