Summary We developed a practical tool that can analyze the quantity of the water under water circulation. The model consists of three sub-models: surface, subsurface, and database. In this model, we have incorporated a function which can precisely evaluate the interaction between river and subsurface and can assess the cultivation water for the paddy field. The model has been applied to the simulation for the Ryochiku plain. The numerical results have been compared with corresponding field observations. Good agreements have been obtained.
