The objective of our study was to apply, test and present the deterministic simulation model SIMWASER computing soil-water balance components. Two case studies for the assessment of percolation losses from irrigated carrots to deep groundwater at Obersiebenbrunn in the Marchfeld (Austria) and ground water recharge and capillary rise from shallow groundwater in grass lysimeters at Berlin-Dahlem (Germany) are presented. Measured and simulated results from field experiments were compared. At Obersiebenbrunn, simulated percolation and evapotranspiration were 183 and 629 mm, resp., whereas the measured values amounted to 198 and 635 mm, resp. In Berlin-Dahlem, simulated capillary rise and evapotranspiration were -122 and 458 mm, resp., whereas the measurement showed -155 and 454 mm, resp. SIMWASER method was a good tool to demonstrate and study plant-soil-water relationships as well as the influence of land use.
