Following its successful calibration, the SALTMED model was subjected to testing against field data of 2002 and all of 2001 and 2000 growing seasons in both Egypt and Syria. The model proved its ability to handle several hydrodynamic processes acting at the same time in nature. Using data from five complete growing seasons in Syria and Egypt, the model successfully predicted the impact of salinity on yield, water uptake, soil moisture and salinity distribution with reasonable degree of accuracy. The results obtained from the observation and simulated data indicate that the Floradade variety of tomatoes is salt tolerant and suitable to grow in the Mediterranean region. The results indicate that water with a salinity level of only 7 dS/m reduced the yield by 50%. SALTMED is a physically based model that can be used in management of water, crop and soil under field conditions. It has 3 built-in databases for soils, crops and irrigation systems. It can be applied on any irrigation system, any soil type, any water quality, any crop and accounts for soil heterogeneity. It calculates evapotranspiration, bare soil evaporation, plant water uptake, leaching requirements, soil salinity profiles, soil moisture profiles and yield.
