Abstract

• The impact of afforestation/deforestation on groundwater recharge can be predicted by using onedimensional soil-vegetation water flow models based on Richards’ equation. However simulations depend upon parameters that are not easily measurable. • Pollacco et al. (2008) showed that the hydraulic parameters can be determined, if the vegetation parameters are known, by fitting simulated time series of soil moisture profiles to those measured in situ. This paper presents a case study to determine if the interception and crop factor parameters can tentatively be calibrated by fitting soil moisture profiles. Synthetic data were used and the other vegetation parameters and the soil hydraulic parameters were assumed to be known.
