1. A method for determining a condition for artificial recharge by using a computer in an artificial recharge system provided with an injection well for injecting fresh water into an aquifer, the method comprising:
a step of calculating a maximum permissible quantity of injection of fresh water to be injected into the aquifer;
a step of determining a height of a screen which is an area on a side surface of the injection well where penetrating holes are formed, based on the calculated maximum permissible quantity of injection; and
a step of determining an injection pressure of the fresh water to be injected into the aquifer, based on the height of the screen,
wherein the screen is formed as high as the height from a lower end of the injection well.
