1. A method of designing an optimized seawater pumping apparatus using a computer in a system in which a seawater pumping apparatus including a pumping pipe and a well disposed to surround a lateral surface of a land-buried portion of the pumping pipe is installed to reduce seawater intrusion in a land in which an aquifer with a seawater-fresh water boundary surface is formed, the method comprising:
applying an optimization algorithm to initial condition data of the aquifer to generate n decision variable sets of the seawater pumping apparatus;
applying an underground water flow model to each of the n decision variable sets to generate n prediction results of change in the seawater-fresh water boundary surface;
calculating a performance evaluation value of each of the n prediction results; and
selecting a decision variable set having a maximum performance evaluation value,
wherein n is an integer and equal to or greater than 2,
wherein the decision varialbe set comprises a height of a screen ofthe well, and the screen is a lower end portion of the well and in which through holes are formed along a circumference of the well.
