Revisit Tidal Simulation of 1592 Hansan Naval Battle

Revisit tidal simulation of Naval Battle at Hansan on 8 July 1592 was conducted by involving the calendar day conversion and tidal prediction in several centuries ago. The Hansan battle is one of three victorious naval battles (Myungryang battle on 25 October 1597, Noryang battle on 16 December 1598 and this Hansan battle) led by Admiral Yi and also famous as the Crane Wing fleet formation during the battle. Conversion between lunar calendar day and solar calendar day before 1900 was taken from Korea Astronomy and Space Science Institute (KASI) because historical documents are written in the lunar calendar.We attempt to reproduce tidal conditions during the most important battles of the Imjin War at Hansan to set up the regional tidal hindcastsystem of old times both by point and by numerical model simulation. The past topographyrapidly changed by developments of coastal area assumed by old documentations and satellite images.
