Info mise à jour: Family Historian Outils Scientifiques. Yves Coquet 2 AuthorId: Wednesday, September 2, – 8: 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. 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. 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 measured values.

A sensitivity analysis of the HYDRUS-1D model was performed based on scenarios that represented the fate of a nonvolatile pesticide in three soils. Merci d’avoir évalué ce programme! Parameter sensitivities hardly varied among the three soils, but this could be due to their limited contrast. Equation Wizard Outils Scientifiques. Tuesday, December 18, – 3: We targeted instantaneous and mean annual pesticide concentration values at 1-m depth as relevant output variables.

As found for other single- or dual-permeability hydris, transient-MIM HYDRUS-1D was highly sensitive to parameters related to pesticide degradation and sorption, especially the Freundlich exponent associated with nonlinear htdrus.

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. Case study Related to pesticide fate in soils. 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.

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

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

Merci d’avoir évalué ce programme! Simulations were conducted with Hydrus-1D code using measured precipitation data for the period and hydfus evapotranspiration for both chosen profiles. Citation Bruno Cheviron, Yves Coquet.

We targeted instantaneous and mean annual pesticide concentration values at 1-m depth as relevant hudrus variables. A sensitivity analysis of the HYDRUS-1D model was performed based on scenarios that represented the fate of a nonvolatile pesticide in three soils. Among the MIM parameters, only saturated immobile and mobile water contents were very sensitive parameters, especially those of the topsoil layers. Reference values for most of the parameters were obtained from in situ or laboratory measurements.

Sensitivity was analyzed by calculating the time-dependent ratio of variation, i. Bruno Cheviron 1 Yves Coquet 2 Details. Me notifier des réponses des autres utilisateurs. Hydrus-1D is a public domain Windows-based modeling environment for analysis of water flow and solute transport in variably saturated porous media.
