...Bruno Cheviron; Yves Coquet Abstract A sensitivity analysis of the HYDRUS-1D model was performed based on scenarios that represented the fate of a nonvolatile pesticide in three soils. We used the latest dual-porosity, transient mobile–immobile (MIM) version of HYDRUS-1D that includes water...

To analyze the ability of the data assimilation approach to track the temporal evolution of these parameters, scenario analyses were performed with increasing complexity. First, the HYDRUS-1D code was used to generate soil moisture and soil temperature time series. On the basis...
