Water and solute flux from the subsurface drains of macroporous agricultural fields are simulated using two-dimensional single-porosity and dual-porosity models. Field-averaged (i.e. effective) parameters are calibrated from drainage outflow and validated for water flow and the transport of non-reactive solutes applied at discrete locations on the field. Both the singleporosity and the dual-por...

The changes in hydrological conditions observed nowadays require economical use of water. This applies to water management both on a national scale and river basins catchments, as well the drainage systems individual networks. Outflow regulation is carried out by extending outflow time surface collected during rainfall various forms retention catchment area. One devices for regulating groundwat...

Abstract. Drainage systems are currently implemented on agricultural plots subjected to temporary or permanent waterlogging issues. Drained account for 9 % of all arable soils in France. As such, the need accurate hydrological modeling is crucial, especially an unstable future context affected by climate change. The aim this paper assess capacity SIDRA-RU drainage model represent variability pe...
