| Description in the original language | Agricultural lands in foothill zones on acid crystalline rocks can be an important source of diffused nitrate pollution affecting the quality of both subsurface and surface waters. Field experiment established to optimise the drip irrigation of potatoes was set up in the highland region. The soil is a deep loamy Planosol. It has capacity to swell and shrink and contains macropores. An attempt is made to explain the major part of the measured spatial variability of soil water pressure by means of dual permeability modelling. S1D DUAL model was used to simulate seasonal soil water suction variations. Inverse modelling was applied in order to minimize the discrepancies between the model responses and observed pressure heads. Levenberg-Marquardt algorithm, was used as a parameter estimator. It is concluded that the measurements of soil water pressure provide valuable information about the physical nature of water flow, and can help us to quantify parameters of dual permeability models. |
