Simulating the fate of water in a soil–crop system of a semi-arid Mediterranean area with the WAVE 2.1 and the EURO-ACCESS-II models

摘要: In this paper. we evaluated the WAVE 2.1 and EURO-ACCESS-II models for predicting crop water consumption, losses by drainage volumetric soil content in a cropped under Mediterranean conditions. A detailed dataset was constructed furrow-irrigated experimental plot on homogeneous sandy soil, with maize during seasons 1992 1993. The calibration validation results of were using both simulation graphics two specific modelling evaluation statistics: root mean square error (RMSE) efficiency. Results showed that are able to predict fate coarse textured irrigated subjected semi-arid environmental agronomical Reasonably good predictions seasonal evolution evapotranspiration obtained models. Soil moisture also well predicted when considering total storage zone plants. However, deviations between observed values increased each layer separately. Sensitivity analysis input coefficient have significant influence made model. value hydraulic conductivity close saturation had Our conditions field sites is required before any purely prediction During calibration, special attention must be given those variables which most affected spatio-temporal variability within field.
