Abstract：We have converted the output data of Water Allocation Model (WAM for short) and imported it into the improved SWAT model (ISWAT for short) which is capable to fetch water from various water sources,and established a coupling model of these two models.After adjusting validating the ISWAT,we applied the coupling model to calculate the amount of irrigation and ET of 8 crops in 13 counties of Tianjin of China.Of the coupling model,the irrigation amount of ISWAT is close to the result of the WAM and the ET amount of the 8 crops is reasonable,which means it is more accurate to couple the ISWAT with the WAM than the traditional SWAT model and the coupling model is able to facilitate basin water management.
